All good knowledge thanks! Point taken on the sequential firing

I bet the staggered firing is an emissions thing. I bet you will not be able to detect a power difference between simultaneous firing and staggered firing on a dyno. ...which means you can just wire both coils on each cylinder together, and run it as if it had 8 regular coils. Thanks - this would s...

16 trigger fully sequential Q1: ... iirc Proteus has enough pins to handle running all 16 ignition channels. From proteus github 16x 4A low-side drivers 12x 5v ignition (or general purpose) outputs If I understand correctly, I would need to use the 16x 4A low-side drivers as the ignition impulses. ...

another project I have in progress (namely a 722.6 standalone controller) do you have a URL? I have no code of my own sorry, as a v1 I am using 7226ctrl One person I have been following recently with interest has taken this project and used it as a base for their own controller - named the ultimate...

Too much text :( I am stretched very thin, I am not very available to help. I feel horrible because in the past many many people have helped me and now I feel obligated to return the favor but I am doing four different rusEFI things in parallel as I type this. I quite understand, your help to this ...

Is there a chance that https://github.com/rusefi/rusefi/wiki/HOWTO-M73-v12-on-Proteus has something relevant? Andrey I really appreciate the speed, frequency and knowledge in your responses. I am looking to confirm my understanding based on your replies on this thread as well as on that board. Plea...

Okay thanks I will look to do this - and then have a separately housed igniter step up component that houses the IGBTs? If I have understood that could we please consider Q1 and Q2 in my first post? I think I can work on this ignition component before buying the ECU, useful as a proof-(to me)-of-con...

Okay to summarise the problem: Proteus standard connections with low current igniters need converting to S500 factory connections and igniter triggers need to be higher current for dumb coils Thank you for the link the the M73 page. It isn't immediately obvious to me why 2 breakout boards have been ...

Thanks to Mark T for supplying the updated wiring harness specific to the S500

Hi thanks for the reply - I do not have any KiCAD experience. Since I have the factory ECU with its connectors, could I desolder the plugs off the factory ecu and connect this to a universal breakout board? What are the strengths and weaknesses of each approach below? Will both fit within a single e...

I have an M113 50 that will be finding its way into a 190e eventually there are two projects in my line of fire before this one gets done, but I am looking to get the engine running by itself sooner than later. The engine is from a 2002 S500, which is useful to note as it is a facelift engine. The e...
