Hey guys, hoping someone can help me with a few PCM questions. I?m running a LS Swap in a 67 C10. The LS is out of a 2004 Escalade and is a 6.0. Obviously the Escalade had a standard belt driven radiator fan that I?ve since swapped to a dual electric fan setup and Vintage Air AC. I have HP Tuners.
My PCM looks to be the original PCM tied to the vehicle-Blue/Green connectors but no provision for the AC request circuit since the PCM is for trucks/SUVs with regular fans.
The fans in my swap do come on and off at the set temps, but I?d like the PCM to handle the idle manipulation when the AC is on.
From my research, it looks like I need a 04 Vette, 04 GTO, or 05-07 V6 truck PCM since they originally used electric fans.
First off, is that correct? If so, can I simply buy the new PCM and have my original VIN flashed in, and then transfer my revised tune from the old to new PCM? I know I?ll need to buy more credits, but is that the way to do it?
Thanks in advance for any information!
