I have a link plugin ecu on my BMW e36 drag car and I'm having an issue setting base ignition timing. With timing locked to 0 degrees I'm still seeing 20 degrees of advance (verified with a timing light). I have played with the trigger angle up and down but timing doesn't seem to move any. It won't move from 20 degrees even when free revving to about 4k rpm. I also get a fault code that says max advance reached. Has anyone else ran into this issue and if so what was your fix? Any help would be greatly appreciated!
