R33 tune now no a/c
So I've had a good search around and can't find much info on this. Basically i had my car tuned 2 weeks ago and it seems that the tune or whatever has been done has stopped my a/c from working. Could this be true? I had a auto elec have a look and he checked everything! and was confused as to way the compressor would not kick in unless it was earthed and the gas was spot on. I told him that its running a aftermarket ecu (powerfc) and he suggested that something could be wrong and it seems to be ecu related. I did a sensor check and its showing 0v Could it be something related to the powerfc?
