Other factors, like weather, fuel quality and that lump of meat behind the steering wheel, also play a role in this process. Set your EGO Switch Point to 0. For example, if you have a narrow band sensor, select that; or if you have a DIY-WB controller select that, etc. Aggressive Mode: use knock retard, but keep advance at threshold of If the ignition timing is off then the combustion process is either too late or too early. This did work quite nicely although I decided that I should also be controlling the engine timing, retarding the ignition on boost to avoid the inevitable detonation that would destroy the engine. This is your ignition timing. [Dan] wanted to learn a bit about solid state ignition in engines; to get started he needed a test subject, so he decided he would upgrade his old 12 horsepower lawnmower. (compared to infinite electronic timing control) - such as vac advance at idle and vac advance at highway cruise - the concept is still to provide the perfect The Apexi Super-ITC was a popular ignition timing controller from the 1990s. In this work, the electronic hardware part includes controller/Arduino with ignition control and fuel injection drivers were used for controlling both ignition timing and fuel injection timings. It can, however, be used to control the timing on a fixed-advance distributor provided that the rotor phasing is correctly advanced. Our company was founded body EFI features a built-in interface that allows the user to have full control of the engine without the need of a PC. Hi, this will be the DIY CDI build and optimisation thread, for harvesting more ignition energy from the original stator resp. Do not use Since you're only dealing with ignition timing and not fuel, your load sensing doesn't need to be particularly accurate. donbryce. I am in the mean time working on a custom motorcycle, and I feel the ignition needs some improvement. i've been working on CDI ignition system. Aim To produce a programmable ignition setup for a 4 stroke 4 cylinder engine with a single coil distributed ignition system, which is advanced through a MAP (Manifold Air Pressure) sensor and rpm read (2D). ) on my car. At 4,000 rpm, the High Speed Retard is activated and the timing is retarded 4° (adjustable with plug-in modules). It will run on the original Speeduino hardware and its derivatives as well as on custom hardware based on the Arduino Mega 2560 processor. Negative therefor not to load the positive pulses RUN TIMING CURVE This is the program for the full ignition timing curve from 800 – 12,500 rpm. That is why it cannot control ignition timing using the the GM Small Cap HEI or Ford TFI ignition. (Figure C) A trace can be selected and moved by holding the shift key then clicking on a dot, this will highlight all dots on the line to and operation of the Control. It's "plug & play" (into the 10-pin ignition connector on the EFI Main Harness) and requires a CD ignition box (Instructions). cranking fuel. or knock comes back. This happens because at higher speeds the piston moves much rapidly than the ignition spark can anticipate it. ) An ignition system Timing Light and Tachometer With Arduino: I created this automotive timing light to check and adjust the ignition timing. The ignition timing check procedure in the Engine section gives different procedures for 4A-FE But it was an easy job, main thing was to make an electric motor to drive the dist, I used an old cooling fan motor from a 2000 or 2010 triumph motor bike , then made a variable controller for it. The advantage is the versatility and the precise control of timing. There were a number of different kinds of General Motors HEI modules: 4 pin module - electronic ignition, but doesn't do computer timing control, top left; 7 pin module (large) - electronic module that does timing control, used with coil-in-cap distributors, top right; 7 pin module (small) - electronic module that does timing control Hello, I am new using arduino. Rev the engine up as high as possible (using appropriate caution/safety). Traces, as found under the Timing>Plots> Engine Speed tab, be can saved and imported using the trace box. Next, cycle the ignition key OFF and then back ON. Since timing is the basis of all engine functions it is critical that, above all else, the ignition system maintain rock ADJUSTABLE TIMING CONTROL PN 8680 IMPORTANT: Read the Instructions before attempting installation. The timing is set very retarded from the factory for epa regulations at the time and I also just converted to e85 which I believe with the high octane will allow to advance timing for more power without sacrificing relability. All ignition systems today are EI. If anyone is looking for an off the shelf super cheap Arduino based full standalone ECU or just programmable ignition, look at Speeduino. Make absolutely sure you have full control of boost and wastegate. I'm not asking for someone to do it for me, just point me in the right direction. Disclaimer: I am by no stretch of the imagination an authoritative on the Boost timing masters, Multi-retard controls, late model controllers <p>I have made many changes to the engine controller. The MSD CD ignition box is wired as shown in the Holley EFI Wiring Manual: There is also a need to control the ignition timing (when the spark occurs) to achieve the optimum burn time for power, economy and for safety (mainly detonation). It is also responsible for pickup signal conditioning, pickup rectification and ignition timing retarding. It is not good enough to just rotate the distributor on older vehicles to get the optimum advance curve because these engines generally could use more initial advance to quicker and at a lower RPM than a gasoline advance curve. The challenge with dual fuel conversions is optimizing ignition timing for each fuel. Can I use transistor to turn on coil? Each coil will turn on many times per second. 1° increments every 100 rpm with 25° retard maximum. </p> <p>A friend suggested the Infineon line of Note: When the Three Stage Retard Control is installed the ignition timing will retard approximately . Adjust and recheck if necessary. Check out our Killshot master Can you check the timing advance with a timing light and let us know what the results are. DIY Ignition Timing. Ignition timing In a spark ignition internal combustion engine, Ignition timing refers to the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke. Most 4T engines in reasonably moderate state of tune will gladly rumble into life with the ignition timing anywhere between +10 and - 5 degrees from TDC. Rescale anything to do with fuel and timing for 200%. In order to control these timings, the position of piston with respect TDC was measured with the help of crank and cam position sensors. Software required for ignition and fuel injection timings with On the controller keypad I typed in this number under "Ignition Setup - Distributor Base Timing". there is a square pulse coming out from the engine flywheel which tell us at which time the ignition coil should produce spark (which is driven by a mosfet ). This is the 'Standard Coil Charging For those car crafters who would rather run a carburetor on a Gen III/IV engine, MSD created the original LS1/LS6 timing control box.

This is "safe mode" scheme is the safest thing for a DIY set-up. The way the system works (at least the basics) I believe, is their is a sensor on one Adjustable timing control units allow you to alter ignition timing via a simple dash-mounted knob. On some occasions I have seen as much a 3 hp from a halfdegree change in timing. msdignition. I started the project using an Arduino mega to control the fuel injectors. You need code that responds to a 'knock' signal by retarding the timing. It has lights setup to help install it correctly. Here's what I like to do with Arduino: Measure revolution time (1 puls per revolution Ford's Electronic Distributorless Ignition System (EDIS) is an ignition system that does NOT require a cam position signal. Programming. Although the CDI circuit initiates the triggering correctly, and tries to complement the piston position, by the time the spark is able to ignite at the spark plug, the piston has already traveled much See more Using a computer-based controller, we can draw whatever ignition timing curve we want at WOT across the whole rev range. Nothing is wrong with manual control just make sure it does what you want and does not have crazy spikes!!!!! Software;. Up to 15 degrees can be added to or subtracted from total timing to compensate for temperature, fuel quality, and other road conditions. Check with the vehicle manual to see if the timing is correct for the given RPM. The Run Timing Curve remains active at all times. Other options include a choice of standard or long spark duration coils in both unshielded and shielded versions. A sensor reads the passing of each trigger magnet and the ignition controller uses this information to apply the correct spark to the engine. - Integrated ignition timing control & coil driver - High Resolution Full Color 5 inch Touchscreen for Note:When the Three Stage Retard Control is installed the ignition timing will retard approximately 4° from its original setting. will work well for you. So if you could design the Ignition Control Module from the Arduino or whatever, and sell . hello forum. Note that for emissions control purposes, a narrow band sensor may be a better choice than a wide With computer control timing is NEVER adjusted just by rotating the distributor. as necessary. The rate of change of the crank speed (not just the speed) is not going to alter significantly over 40 o or rotation. After cranking over the engine and using a timing light I matched the reported timing from the controller display to what I know I set my timing at. including the CDI unit, ignition coil, capacitor, trigger coil, and spark plug. Plus, the distributor over time wore out and affected the timing control. We can also vary the amount of advance at light Coming to my project, this is a request for you folks to help me build a digital programmable/mappable ignition system for a two stroke engine.

I am in the mean time working on a custom motorcycle, and I feel the ignition needs some improvement. i've been working on CDI ignition system. Aim To produce a programmable ignition setup for a 4 stroke 4 cylinder engine with a single coil distributed ignition system, which is advanced through a MAP (Manifold Air Pressure) sensor and rpm read (2D). ) on my car. At 4,000 rpm, the High Speed Retard is activated and the timing is retarded 4° (adjustable with plug-in modules). It will run on the original Speeduino hardware and its derivatives as well as on custom hardware based on the Arduino Mega 2560 processor. Negative therefor not to load the positive pulses RUN TIMING CURVE This is the program for the full ignition timing curve from 800 – 12,500 rpm. That is why it cannot control ignition timing using the the GM Small Cap HEI or Ford TFI ignition. (Figure C) A trace can be selected and moved by holding the shift key then clicking on a dot, this will highlight all dots on the line to and operation of the Control. It's "plug & play" (into the 10-pin ignition connector on the EFI Main Harness) and requires a CD ignition box (Instructions). cranking fuel. or knock comes back. This happens because at higher speeds the piston moves much rapidly than the ignition spark can anticipate it. ) An ignition system Timing Light and Tachometer With Arduino: I created this automotive timing light to check and adjust the ignition timing. The ignition timing check procedure in the Engine section gives different procedures for 4A-FE But it was an easy job, main thing was to make an electric motor to drive the dist, I used an old cooling fan motor from a 2000 or 2010 triumph motor bike , then made a variable controller for it. The advantage is the versatility and the precise control of timing. There were a number of different kinds of General Motors HEI modules: 4 pin module - electronic ignition, but doesn't do computer timing control, top left; 7 pin module (large) - electronic module that does timing control, used with coil-in-cap distributors, top right; 7 pin module (small) - electronic module that does timing control Hello, I am new using arduino. Rev the engine up as high as possible (using appropriate caution/safety). Traces, as found under the Timing>Plots> Engine Speed tab, be can saved and imported using the trace box. Next, cycle the ignition key OFF and then back ON. Since timing is the basis of all engine functions it is critical that, above all else, the ignition system maintain rock ADJUSTABLE TIMING CONTROL PN 8680 IMPORTANT: Read the Instructions before attempting installation. The timing is set very retarded from the factory for epa regulations at the time and I also just converted to e85 which I believe with the high octane will allow to advance timing for more power without sacrificing relability. All ignition systems today are EI. If anyone is looking for an off the shelf super cheap Arduino based full standalone ECU or just programmable ignition, look at Speeduino. Make absolutely sure you have full control of boost and wastegate. I'm not asking for someone to do it for me, just point me in the right direction. Disclaimer: I am by no stretch of the imagination an authoritative on the Boost timing masters, Multi-retard controls, late model controllers <p>I have made many changes to the engine controller. The MSD CD ignition box is wired as shown in the Holley EFI Wiring Manual: There is also a need to control the ignition timing (when the spark occurs) to achieve the optimum burn time for power, economy and for safety (mainly detonation). It is also responsible for pickup signal conditioning, pickup rectification and ignition timing retarding. It is not good enough to just rotate the distributor on older vehicles to get the optimum advance curve because these engines generally could use more initial advance to quicker and at a lower RPM than a gasoline advance curve. The challenge with dual fuel conversions is optimizing ignition timing for each fuel. Can I use transistor to turn on coil? Each coil will turn on many times per second. 1° increments every 100 rpm with 25° retard maximum. </p> <p>A friend suggested the Infineon line of Note: When the Three Stage Retard Control is installed the ignition timing will retard approximately . Adjust and recheck if necessary. Check out our Killshot master Can you check the timing advance with a timing light and let us know what the results are. DIY Ignition Timing. Ignition timing In a spark ignition internal combustion engine, Ignition timing refers to the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke. Most 4T engines in reasonably moderate state of tune will gladly rumble into life with the ignition timing anywhere between +10 and - 5 degrees from TDC. Rescale anything to do with fuel and timing for 200%. In order to control these timings, the position of piston with respect TDC was measured with the help of crank and cam position sensors. Software required for ignition and fuel injection timings with On the controller keypad I typed in this number under "Ignition Setup - Distributor Base Timing". there is a square pulse coming out from the engine flywheel which tell us at which time the ignition coil should produce spark (which is driven by a mosfet ). This is the 'Standard Coil Charging For those car crafters who would rather run a carburetor on a Gen III/IV engine, MSD created the original LS1/LS6 timing control box. Originally the lawnmower Proceed to Section II: Ignition Timing . Hello everyone. Parts Included: 1 - Retard Control, PN 8975 4 - Mounting Screws Note: The Digital Retard Control must be used with an MSD 6, 7, 8 or 10 Series Ignition Control. 450 volts for a narrow band sensor, stoichiometric for a wide band sensor (2. This is "safe mode" scheme is the safest thing for a DIY set-up. The way the system works (at least the basics) I believe, is their is a sensor on one Adjustable timing control units allow you to alter ignition timing via a simple dash-mounted knob. On some occasions I have seen as much a 3 hp from a halfdegree change in timing. msdignition. I started the project using an Arduino mega to control the fuel injectors. You need code that responds to a 'knock' signal by retarding the timing. It has lights setup to help install it correctly. Here's what I like to do with Arduino: Measure revolution time (1 puls per revolution Ford's Electronic Distributorless Ignition System (EDIS) is an ignition system that does NOT require a cam position signal. Programming. Although the CDI circuit initiates the triggering correctly, and tries to complement the piston position, by the time the spark is able to ignite at the spark plug, the piston has already traveled much See more Using a computer-based controller, we can draw whatever ignition timing curve we want at WOT across the whole rev range. Nothing is wrong with manual control just make sure it does what you want and does not have crazy spikes!!!!! Software;. Up to 15 degrees can be added to or subtracted from total timing to compensate for temperature, fuel quality, and other road conditions. Check with the vehicle manual to see if the timing is correct for the given RPM. The Run Timing Curve remains active at all times. Other options include a choice of standard or long spark duration coils in both unshielded and shielded versions. A sensor reads the passing of each trigger magnet and the ignition controller uses this information to apply the correct spark to the engine. - Integrated ignition timing control & coil driver - High Resolution Full Color 5 inch Touchscreen for Note:When the Three Stage Retard Control is installed the ignition timing will retard approximately 4° from its original setting. will work well for you. So if you could design the Ignition Control Module from the Arduino or whatever, and sell . hello forum. Note that for emissions control purposes, a narrow band sensor may be a better choice than a wide With computer control timing is NEVER adjusted just by rotating the distributor. as necessary. The rate of change of the crank speed (not just the speed) is not going to alter significantly over 40 o or rotation. After cranking over the engine and using a timing light I matched the reported timing from the controller display to what I know I set my timing at. including the CDI unit, ignition coil, capacitor, trigger coil, and spark plug. Plus, the distributor over time wore out and affected the timing control. We can also vary the amount of advance at light Coming to my project, this is a request for you folks to help me build a digital programmable/mappable ignition system for a two stroke engine. The DIY ignition to me looks promising simply because I AM CHEAP and don't like to support the scalpers that with to charge mega bucks for the original module that General Motors HEI Ignition Control with MegaSquirt-II. amount. This ECU installs on ’80s era GM engines like it was designed for them, which isn’t far from the truth since it comes pre-calibrated for all GM sensors. This allows you to MSD IGNITION • www. I posted my prefered dist for timing control and it is not for everyone. I will use 8 ignition coil on arduino. Maf. Hi, I've fiddled a bit with Arduino basic stuff, and my bigg plans for an EV controller have stumbled upon legislation, so that has never really taken off. dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. CARBURETOR The PN 6010 Ignition Controller is designed for GM Gen III engines that have been retro-fit with an intake manifold and carburetor. Finally, in this work, not only the APC results are presented but also a comparison with the existing control design in the test vehicle and with a gain scheduled Smith Predictor are provided. V8 Timing control-Brainstorming-Need help and suggestions for a new project. controller/Arduino with ignition control and fuel injection drivers were used for controlling both ignition timing and fuel injection timings. Welcome to the CDI-2012 DIY Open Source Programmable CDI Project using the PIC12F1840. VTC = Variable Timing Control (rotating cam) - VTC is a system that continually changes intake camshaft timing by a total of 50 degrees Modification of the pump/race gas timing and cam timing maps will be sufficient for most users. 500 volts for the DIY-WBO 2 for example). This provides for real-time stoichiometric mixture control for a chemically 'perfect' mixture. " Read the degree mark lining up with the timing mark. As little chargecoil function control. 1. This computer shoved in the engine compartment controls just about every aspect of your car’s performance, from the air/fuel ratio, the ignition timing, and the valve controls.

Altronic However the knock signal by itself is not sufficient for detonation feedback ignition timing control MegaSquirt-II. The ignition coil amplifies the Ignition advance angle. 2 Block diagram for Idle Speed Control ω ei= ωeiU, T e≤ T L ω U −ω T e−T L,T < T≤ U ωeiL,Te > TeU (3) where ωeiL and ωeiU are the lower and upper engine speed limits for idle control and TeL and TeU are the cold and warm engine coolant temperatures, respectively. ) In a standard system, the coil 'sparks' when the current to the coil is interrupted. com • (915) 857-5200 • FAX (915) 857-3344 MSD Digital Retard Control PN 8975 IMPORTANT: Read the Instructions before attempting installation. I'm new here, to this awesome forum, and I wanted to ask for your opinions. It has no part-load advance. Projects like Scooterputer and Speedoino have given me ideas for dashboards for a scooter. If anyone can give me a circuit to adjust the spark trigger signal timing I will be most grateful. It is ignition indicator signal to control ignition system work. . It can function with just a variable reluctor crank position sensor and a 36-1 tooth wheel (36-1 means '36 teeth minus one', and refers to 36 evenly spaced teeth, one of which has been removed). Selecting an ignition system for a racing engine requires consideration of several important factors. Ignition timing can make or break your car. The 3-Stage Retard Control can retard the timing three different times and each with an individual . Depending on your engine and power adder combo, you can have the ECU manage power a number of ways: Spark Cut, Ignition Timing Retard, Nitrous PWM reduction, Add Fuel, Here's the ghetto spark cut rev limiter tutorial everyone keeps asking for. Most of the ignition system components have remained the same for all NG6 engines. the module itself, will be based, on 1-2 atmega328 chips, and Hello, I have a 2003 dirt bike that I would like to adjust the timing for. The ECU gets hundreds of inputs which help it to adjust Learn how to build a DIY CDI ignition circuit for your motorcycle or small engine, with a step-by-step schematic and detailed instructions. The timing of the spark is determined by a Hall effect sensor reading a magnet placed on the flywheel. Ford's Electronic Distributorless Ignition System (EDIS) is an ignition system that does NOT require a cam position signal. It would appear that the alternating signal is stored in a capacitor in the CDI unit until the spark trigger signal is processed (once per rotation), whereupon the charge in the capacitor is release into the ignition coil causing the spark. These parameters should be used when having the KILLSHOT EFI control the ignition timing to sync actual engine timing with commanded timing. Essentially it advances 1 degree per 100 rpm up to full advance. Ease of service is assured by the replaceable back cover, which contains all the system electronics. After installation, the timing should be checked and adjusted . I recently bought a scooter and I was thinking about the feasibility of using Arduino (I have almost unused duemilanove) as a CDI unit (Capacitor Discharge Ignition system controller). 8K views 10 replies 5 participants last post by ulysess1966 Feb 22, 2005 As for starting, the timing at start is NOT critical. In the example, the total timing is set at 35°. 4-20 milliamp signal. Note Stock tune Fuel and timing values. 8: 2267: May 5, ignition functions. The best ignition timing depends on the relationship between the crankshaft speed and the combustion rate of a mixture of a given composition. The Adaptive Posicast Control (APC) is a recently developed control 7 JournalofControl,AutomationandElectricalSystems(2023)34:554–565 557 Fig. Honda spec is 15* idle/base timing, full advance at 4500-5350 rpm at 43* +/-2*. The Ford EDIS System. Unless you working on old vehicles a timing light is like a dinosaur. Ignition advance angle is the angle at which the crank of the crankshaft does not reach the top dead center at the time a spark appears between the electrodes of the spark plug. Give you a pat in the back! DIY electronic timing control - S-ITC Jump to Latest 1. I'm working on some equally cheap, much betterer working rev limiters. Even the harmonic balancers on the crankshaft aren't keyed in place, just press fit on the crank end. Whether you're a car enthusiast or a DIY After many months of test driving, the latest DIY engine control board has arrived! This PCB incorporates the same 2-sensor fuel injection system as my previ Those wanting to change from points and want to utilize this system will need to put out for the timing cover, the magnet sensor wheel, a new crank key and the timing cover gasket. **Optimum Timing map; Cam Position 1** {KFZWOP} X Axis = RPM Y Axis = Load Cell Values = Ignition Angle Description: This The ECM is actually a full EFI system, and you'd only use the ignition control portion, and maybe other useful features like radiator fan control, rev-limiting, idle controls, etc. This is a feasibility inquiry regarding a project I have in mind: The scope is that I have a motorcycle engine to which I want to add a programmable Ignition controller in place of the current mechanical system (which has failed me and cost me a holed piston and an engine rebuild). Energy saving and environmental protection is the mainstream in the development of the car, with more attention paid to the natural gas vehicle. but the problem is that the pulse comes out is 40 - The Civic Si stock ignition timing is not conversative - It is VERY sensitive to the knock sensor - Once tuned, there is more power, yet the same or better emission, and better economy. I currently am running a coil module (GM HEI) triggered by the points via a transistor I have done a bit of looking around and the likes but cannot find any hard answers. 457 posts · Joined 2002 Add to quote; Only show this user Check that the ignition timing mark (yellow) on the crankshaft pulley and the timing mark on the timing belt cover are aligned. Note: The PN 8762 must be used with an MSD Ignition Control. I'm really curious if this setup stops advancing the timing before 5500 or if it continues to advance. This spike is the signal the Hall control uses to release the coil ground at terminal 1. After installation, the timing should be checked and adjusted asnecessary. Understand its impact on performance, factors affecting it, and the latest advancements in technology. These distributorless ignition systems instead use a crank trigger to establish base timing, and then control most other ignition parameters electronically. systems and ignition components, geared toward -doit-yourself automotive enthusiasts. housing slightly to matchthen turned off static timing, set all timing modes to 44 degrees, for uniformity, and checked at roughly 3500 rpmsit was slightly off, so I added to the INDUCTIVE DELAY a few times, until it Sparkduino is a user mappable, distributor-less, crank-fired ignition system that can be used on a variety of engine configurations. INTRODUCTION Upgrade time! Yanking my HEI distributor, and replacing it with a MSD ProBillet 2 wire, to utilize FiTech's built in electronic Timing Control. Greg / February 17, 2017 / DIY. Rotating the distributor may change the timing but usually not in the way you want it to change and will often screw up other things because the where the computer thinks the timing is and where it actually is is no longer in sync. Our EFI Tuners Guide is aimed first and foremost to the DIY EFI installer, configurer, and tuner, this guide will help you understand WHY you want to consider Electronic Fuel Injection, how these systems work, and how you can Now you set up the Traction Control Reactions. My ignition controller interface uses the following: • 3 adjustable rev limiters in 50 rpm increments o 1 for burn out use a switch o 1 for staging – foot brake (switch) or trans brake o 1 for Max rpm • Adjustable timing in 50 rpm increments to 10,000 • Adjustable timing by the tranny gear- use switches (3) Aftermarket crank trigger ignition systems, like those available from MSD, use trigger wheels with four small trigger magnets positioned at 90-degree increments on a wheel. 4° from its original setting. It can control a HEI ignition and the stepper motor idle control found on these engines using its standard hardware. i have made everything except for one thing which is a ignition advance retard using microcontroller. i am making this topic, because, it is a project, i am planing on beginning soon, and i know many on this forum have also done simmilar things to this.
