Title: Need help with Megasquirt / Car backfires when cranking
Post by: evanbennett on October 18, 2017, 01:22:34 AM

I have been working on getting my m42 N/A e30 running a microsquirt v3 ecu. I don't know if I am the first to use this ecu+engine combo. The issue I'm having is that whenever I crank the engine over It struggles and backfires, and keeps backfiring as I'm cranking the engine. I am new to engine management and not sure if I have something wired wrong or something in the tune misconfigured. I can post my tune when I have the time to pull it off the other computer in the garage. I'm in the bay area if someone that knows how to tune these engines lives around here.

I would appreciate any input!
