I can't seem to find any free or demo software to read an LT1 OBD2 PCM from a 96 TA. Does anyone know of such a thing? All I want to do is read the PCM to help me determine what's been done to the engine and if anyones tuned it before. I have Tunercat for OBD1 and winflash but nothing for OBD2.

 

There isn't one that I've ever heard of. I've got a basic obd2 scanner I don't need anymore. $100 shipped. LS1m is the type. It'll do full ls1 reading/datalogging but not enhanced for LT1.
