Forum Introduction
Hello all. I've been slowly building a fleet of gmt400s with many future plans of engine builds needing tunes. I had a go at using Microsquirt on a 383 swapped 94 Blazer, but the further I got the more I needed to add on to retain practical street driving (IAC, Knock Control, Injector Resistors, Trans Control, and even more). Figured with all this I am better off using the factory 7427 ecu that will have everything needed and have all the factory diagnostic codes and such. Ill be searching the forum a lot I imagine and hopefully be able to learn and give back if there are gaps in information available.

Thank you, I appreciate it. Man there is quite a difference between Tunerstudio and TunerPro. So many little parameters that GM made vs a generic ECU.
