Hey everyone, kinda new to the forums I guess. Well, I bought my single turbo FD in January and now its starting to get hot in FL, so I need A/C!. So my car idles at around 850-950RPM with the A/C off, but once i turn the A/C on it gets into the low 700's and causes the engine to die sometimes when I disengage the engine. I have a PFC that I'm trying to learn how to use, I've changed all the idle settings but it seems to do nothing at all. Please help?

Thanks,
Max

The power fc needs to learn the idle with the ac off then with all loads on the engine search for power fc in the forums and you should be able to find your answer

I like to have the idle speed on the power fc set to at least 1000 with the ac on. Higher on cars with big port. Just go into settings and the rev/idle menu and raise the idle setting. If it doesn't respond you may have a problem with the iac valve or the throttle body is adjusted wrong.
