Hi folks,
I come from Porsche land, but now I am using GM ls3. Not new to tuning but my case is I need to pick up on tuning the ls3 GM ecu. I do not get what credits are, technically if I create a tune it is my art. But my art van only go to gallery with credits? Not understanding GM here. Anyway, I have a base tune in my motor, vehicle runs OK but I need to tweak it a few hundred times, or if that don't work out, start over with what I paid for in the crate motor. If I put have MVPi2 why do I need credits to fix what is broken from an out of the box crate tune? Everything is stock ls3 and only MOD is headers because cast would not fit the Porsche body. Do I need 2 credits to be able to unlimited edit my existing tune? And if that don't work out and I start with crate tune, that's another $100? Appreciate input on this contraption so I can work and have no cost from mistakes.
