Hello all,
I'm pretty green to EFI live as I recently got an old V1 from a friend of mine. I had a PCM short out on me and after I replaced it with another I flashed the old PCM's tune onto the newer one and suddenly I have issues with plug fouling. Basically the truck fouls every plug within 30 minutes, carboned up black as coal. I just got my wideband in a few days ago so I haven't had time to hook it up yet to get an actual AFR. My friend suggested running it in open loop all the time to see if that changes things. Can someone please help me?
Truck is an 02 Silverado 2wd, forged 408, Vic Jr manifold, 4 bbl 1000cfm TB, Racetronix 44lb injectors.
Thanks a lot!
