Is it possible to make Hp Tuners read only the TCM and then write only the TCM?
I have an 81 camaro with a LS3 and 6l80e. The kicker is the MAST motorsports harness and computer the engine runs on. Hp tuners or even a Tech 2 recognizes the software in the Mast ECM.
Im trying to reprogram the Tcm, but since everything has to connect with the ECM first, its not letting me do anything with the Trans.
