Flash/Tune new PCM
Hey all,
Hey all, I've recently been converted to the world of the LS. How did I ever live without them! So far I've switched over the truck and daily driver to vehicles LS based and I'm now in the midst of converting the race car.
I've managed to source an LS3 but it came from an SUV so having to get rid of the DOD etc. I'm also sourcing a new PCM, harness, throttle body and pedal to bring the build up to snuff.
The one question I have (and my endless searching on the internet etc fails to reveal - probably user error) is about programming a new PCM. My tuner is concerned that it will need to be benched tuned. It sounds like a new PCM has to go through additional steps to a pre-programmed PCM?
Can anyone advise? I assume it has to do with the fact that a virgin PCM has no idea about what vehicle it is etc?
