Hi guys,
I run HPT 2.2 to tune my '05 C6. There is something that does not seem to work on my car as well as others with the same PCM (E40) ala '05 and '06 GTO's. Not sure if it affects the latter LS2 PCM's. I'm trying to figure out if it is a bug in HPT or the GM OS.
In HPT, much like EFILive, there are parameters for turning off the AC compressor when a cetain RPM and/or TPS is reached. I've tried all sorts of values for these parameters and log the AC compressor and AC compressor disable status bits and these parameters seem to have no effect.
So my question is: Can anyone tuning a similar vechicle with EFILive confirm whether this works or not for them?
