hey guys. so i have a blacktop sr but with a redtop harness and ecu. now my ecu was modified from the dealer that i got the clip from, i had it read, rev at 8100, speed limiter removed and a conservative tune but not a bad tune. now, i have a buddy with a redtop and we tried swapping computers a while back to see if a stock ecu would run my motor better (this was before i had the ecu read) and the engine started and ran like **** and wouldnt rev past 3k like a bad MAFS. anyone think they know what could cause that? its really no big deal cuz like i said my engine runs great with my ecu, it just wont run with his.

Maybe your motor came w/ a different MAF that your ECU was tuned for?

eh, seems like he yanked the ecu out of a pile. like i said blacktop motor and redtop ecu, i didnt get them together so the ecu was really tuned for a different redtop motor. goofy problem huh?
