ecu

well i had a ecm issue and had it repaired. 700.00 later the first code i got was p0601 bad ecu then got it back and code p0315 came up took it back and they taught the crank sensor. i could not rest it. then yesterday the same code but i was able to reset it. so i left the scan gage on it to...

i have a 2005 ls and i was wondering if i took a ss or sport gauge cluster that goes up to 140 or 160 could i use that in my car? or do you have to have a specific cluster for the car? thanks.

I was talking to a guy who has a lancer and he said he has a Piggy Back ECU and it helps his engine. Anyone running one on a cobalt. He says there are maps designed for different cars. He has a Split second box i think. Its like a external ecu.
