Here it is the ECU Finished with the module inside the ECU ... it uses 4 pins for the coils . A19 , B3 , B4 , and D5

Re: OBD1 ECU COIL ON PLUG MODULE - TROJANTUNING
Can you elaborate at all about this?

Well , it all started here, but not a lot of response from people . but the whole idea was to create a cheaper option for coil on plug for OBD1 . https://honda-tech.com/engine-manage...-pack-3274406/ |
Re: OBD1 ECU COIL ON PLUG MODULE - TROJANTUNING
So what have you done with the distributor sensors ??? Using this ECU combined with the D17A architecture makes the job easier than using your board and ECU combination on a B, D, or H series engine. How do you intend to integrate your system with these engines ??? If you can remove the conventional distributor, you will have a winner.

Re: OBD1 ECU COIL ON PLUG MODULE - TROJANTUNING
Those gains would be better realized on a car making more power obviously. But so far so good!

Re: OBD1 ECU COIL ON PLUG MODULE - TROJANTUNING
hondata is probably looking for ways to sue you as we speak lol
post it on pgmfi.org forum we need a project to keep tat forum alive:) pgmfi.org is somewhat part of Honda history by now... |

well , I just came back from dyno, I understand there is some tuning necessary on this but blue line is without COP and red with COP , Im having an issue with the dwell at high RPM . I have to lower it down to 2.3ms so it doesn't desynch but I lose a little bit of power , plus there is a difference of timing with COP , probably because the signal is processed faster in the microcontroller than the mechanical parts inside the dizzy , an offset of around 5-7 degrees adv , an offset conf will fix that , but not a huge issue that cannot be resolved . if there is someone that is willing to help in the project who knows about arduino and microcontroller programming is more than welcome , Im going to keep working on this to make it better and make a dynamic dwell programming also to avoid the desynch problem and finish it.

very nice work, would you make public the code?

Look into the uc32 boards from ChipKit. They're 32 bit Pic-based and run at 80MHz (Arduino Uno is 16bit/16MHz), so basically double the precision at 5x the speed. Same form factor as the Uno and their IDE takes Arduino code directly so you can drop your current sketch right in and tweak it from there.

hope not lol , I think I have to re enable my account there , its been a while since I posted in that forum . its been dead for a long time . what happened with that lawsuit by the way ?

that uc32 looks very nice , but to be honest Im looking to make it even smaller, plus if you do the math , I only need a proc that can handle 6Mhz that will be good for 13K rpm , unless we are installing this on bikes lol . but thanks for the tip , Im actually getting one for another project I have .

Re: OBD1 ECU COIL ON PLUG MODULE - TROJANTUNING
I was working on this at one point but never got to the point of testing it on an engine, just had it running with the engine simulator on the bench.
Feel like posting your code? I assume its all running in the Arduino IDE since youre using the board. |

You couldn't be sued for your device, there's nothing there to infringe on their IP. They didn't invent COP or hold patents on it.
I figured, just throwing it out there as an option to get into 32 bit without re-prototyping the whole thing or learning another code base. I would asssume that your end goal is a proprietary board. I think it would be worth the $30 to experiment with. Im starting to consider a little more the board cause Im adding the Offset Retard to adjust the timing to the correct number and also thinking about the Dynamic Dwell . |

This is the first revision of the micro controller programming , as of now , I take no responsibility of the use of this information . this is the beta version and its just for development purposes.

Why is that a zip file? it's only 147 lines of code.

Re: OBD1 ECU COIL ON PLUG MODULE - TROJANTUNING
Good job!
In later engines (such as F23's as I know), the sensors are located at the crank pully side of the engine. I think in those engine the dizzy is just working as a distributor and coil, not like the older ones which contain sensors too. If I'm correct, you could completely remove the dizzy in those engines; Which makes the bay more shaved and clear. What you think? |
Re: OBD1 ECU COIL ON PLUG MODULE - TROJANTUNING
Well the one on the crank in the later engines is a crankshaft fluctuation sensor, part of the obd2 system's misfire detection strategy. It doesn't actually have to do with timing the engine, but can be used for such with an alternate setup. You can't run an engine with only crank signal though. There has to be a sensor on the cam or the engine cannot sync.
