Re: PCM swap problem
Yes it's with the scanner. And just to verify, I used a friends scanner and it read the same thing. Those numbers are not static...they fluctuate depend in throttle position. We also tried both scanners on his '03 s10 and the advance was on the positive side 17-30*, again depending on throttle position. Same with my wife's '02 Blazer. I'm at a complete loss. When I put the new engine in my truck, I had the transmission rebuilt with a Beast sun shell, Redline bands and clutches, with extra clutches and a Corvette servo. With the Blazer ecm in it, this thing gives some nice kidney punches with no lag between shifts. With the original ecm...it's just ok, so I'm thinking the + advance really wakes this thing up. I also went on a 250 mile road trip...milage went from 17.5 to just short of 21. If I could find someone to figure out how to turn the offending dash lights off on the Blazer ecm, or fix the advance on mine, I'd be a happy camper.
I'll takes screen shots of the scanner with both ecms
