7875 + 5.9 + E85 + Megasquirt

Still putting this thing back together. Wanted to take it for a test drive today but the engine is running like ****. Not sure what happened. Can’t even get it out of the garage. Back firing thru the intake and exhaust. The AFR hunts all over the place when idling. I got a few logs I need to go through and see if I can narrow it down.

Oh no not you too, damn electrical gremlins. Hope you get yours sorted out sooner then I do, I'm still stuck waiting on fuel filter elements from Summit, to see where my gremlins are at or if they are fixed.
