Crash course for GM TPI

Post by Mykk » Tue Oct 23, 2018 2:56 pm

Hey guys, is there an online tutorial or guide for navigating the GM TPI ecm's, .xdf and .bins?

I am familiar with OBD1 BMW Motronic chip tuning. I'm familiar with carb & dist tuning small block chevies as well as modifying OBDII GM by way of HPtuners. But this is my first OBD1 GM.

The cam is too aggressive for the hypertech chip, so I'm going to need to dial in things further. Thanks for any advice, leads & input
