No, because the Pettit ecu just adds chips to the stock ecu to adjust fuel and timing. It leaves the rest of the stuff alone.

BTW, the PFC does not "mess up" the AC, per se. It mostly only causes problems with 93 cars first of all. Secondly, people who had A/C problems and replaced the wiring harness have reported that fixed the problem. See Chuck's posts on the issue in the ecu forum.
