I guess I misunderstood the OPs question. I thought he wanted to let the PCM turn the fan on when the AC came on also (like using a GM style pressure switch in newer cars). I also have the GMPP harness, VA, and Entropy stuff. The entropy controller seems to do a great job, those fans pull some amps though!


Similiar stall issues. I have talked to a couple of other guys that have experienced the stall also with the GMPP setup. I am not running a GM crate cam and have had my car tuned accordingly.
