I'm new to the tuning scene and just purchased the setup for tuning an 03 gen III in my Crawler. Whats in it now is a Vortec from a 97 Tahoe. The tuner will not seem to read that ECM. I have no idea what the VIN is for that setup. Is there a way to make it read that ECM?
I'd like to put the Vortec setup in my daughters 79 K10 but I need to, or would like to modify it for her. Any ideas?
