I'm new to the world of ECM tuning and would really appreciate some help. I didn't have luck with a search so here goes....
I plan to use the factory harness with an E38 ECM and pair it with a 4L80E transmission. The Escalade was set up with a 6 speed.
Can anyone here recommend a factory application that will work for on my ECM with VVT and the 4L80E trans so I can use it as a base tune?
Thanks in advance!
Doug
