I'm posting this here rather than on LS1Tech or LS1GTO because my main concern (fear) is the tuning side of things.
My original purpose for purchasing HP Tuners was to use it on my '05 GTO LS2/T56 I had planned on putting in my BMW 540i with a pair of GT35R's.
4 Years later, I have purchased other cars, a house and still have no touched the BMW, in fact the GTO, despite missing some parts I've sold, still runs and drives perfectly. I've used HPT to disable the VATS in the GTO, as well as the LS1 I swapped into my 52 Cadillac and disable a few other things.
I'm now selling my BMW and I was thinking of tossing the LS2/T56 into a 67 Chevelle or perhaps my 70 El Camino thats been sitting for years as well, but I think I may part ways with the El Camino or just stick the LT1/T56 I have sitting around in it.
Finally, I think I convinced myself to toss the LS2 into my Typhoon, however to make this work, I need to ditch the T56 and convert it to a 4L80E. Little did I know, that isn't such an each chore since the '05/'06 has a separate TCM and on the M6 cars there are even more steps involved to getting the 4L80E to work.
I hate the fact that I already wasted credits disabling things on the LS2, but I think the only sensible thing to do is just unload my complete LS2/T56 and go buy a 2001+ 2500HD and start over?
I guess I'm just looking for reassurance that its going to be the best way to go and not end up with a hacked up, spliced harness abortion PCM code vehicle when all is said and done.
I do not want to run a stand alone TCM, manual valve body is out of the question too. Am I overlooking anything that would enable me to keep the current engine/PCM I have?
Thanks.
