Support for GM/Delphi MEFI 4/5
I know this has been covered before, but I think there's a pretty good size market for support for these controllers (MEFI-4, 5, 6, 7). I have 3 MEFI-4's collecting dust in my shop unused. I could put one up for testing if that would be enough to get the ball rolling. I don't have a MEFI-5 sitting around. I'm working on a LS-3 powered pre-runner now, and I would have used one of the MEFI-4's I have, but the software to reprogram would cost me a bundle from https://www.mefipro.com/index.html
The MEFI-4/5 is used quite a bit by companies like Brenthel and Alumacraft in their GM LS powered off-road 6100 class, Class 1, and Pre-runner buggies. The off-road crowd loves them. And there a ton of marine builders that would be happy to see alternatives.
From what I've researched on the MEFI-6, they are essentially a GM Gen IV ECM. And I've heard rumors that it's the same ECU that Polaris uses on their Ecotec powered Slingshot.
