Re: Reverse Engineering ME7.4.4 as a stand alone ECU
Yeah quite a bit, I've added a lot to the code but not much recently, there are a few people in our discord that are using it too modified for their own builds, different trigger wheel patterns, drive by wire etc

How much info is there for coding these from scratch?
Don't stress specific units.

Can this be configured to run not only speed density, but also in Alpha N mode.

Re: Reverse Engineering ME7.4.4 as a stand alone ECU
Yes! A couple of people using this ECU have prety big cams with very little vacuum and have modifed the code to run alpha-n. I've added my own alpha-n into the main code fork and once we have it tested and confirmed working as it should, we'll release an update. The beta firmwares from myself and others are all in our discord if you wanted to see what we're all up to. I'm currently working on adding 60-2 trigger wheel support, others have it working but there are bugs they can't track down. I've just set up a bench trigger wheel to hopefully identify if its a spark timing or spark dwell issue.

That is interesting. Where can this special firmware be found.BennVenn wrote: Fri Sep 05, 2025 6:55 am Yes!
