Getting close to lighting off my LS swap for the first time but wondered which way to go on the PCM programming. Its a 0411 ECM that was with the original 4.3. Can I just change the engine platform to the 6.0 specs and do a calibration swap. The segment swap option doesnt come up when I try to do it that way. Just don't want to blow $100 on a PCM tune that wont work.
On my last LS S10 swap I got lucky and used a stock Tahoe ECM and all my gauges worked. Guess I could clone another tune from one of my S10 swaps but would be nice if the vin matched the vehicle this time.
thanks
