we have a cammed 4.8 that was in a 2000 chevrolet silverado 2wd with a tbss intake and long tube headers a drive by cable pcm that was red/blue plug. we pulled motor from the 2000 and installed it into a 2005 gmc sierra 4wd and had to use stock manifolds and stock 5.3 intake with drive by cable. Tuner instructed that we transfer all tune info from 2000 tune file to the stock 2005 ecm and relicense computer to be able to run motor. Problem we are running into now is that when engine is off we can watch throttle position go from base to 100 percent. Once engine is cranked it runs fine like in the 2000 truck but throttle signal goes away and has zero throttle. can anyone please help on whats going on read a few forums that said change etc in setting all to 0 did that and problem didnt change. Also one problem is truck was cranked on stock tune with ground in wrong place the motor started and stalled and started showing the little lock icon with vehiclke behind it ground was properly moved to block and now it starts and runs just no throttle signalafter tune and also vats turned off . Any help would be apreciated. Tune file should be attatched.
