Surging idle when the A/C is on
I just got my PFC and the car idles pretty high(1500) and then slowly settles down to 1000. But when the A/C compressor is on the idle surges between 1100 and 500 constantly. If I turn off the A/C the idle stabilizes to 1000. Is there a setting that I need to tweak? Or coould a belt be on too tight or something?
I also just had a ported motor and 1300cc's installed along with the PFC. The car isn't tuned yet. I just uploaded ZeroBangers .dat(datalogit) file into my PFC. Since we have similar mods.
Does anyone have any ideas on how to adjust PFC idle settings?

I had a problem with my PFC at first with idle stability. I fixed it by resetting the PFC and actually giving it the 15 minutes for each stage of idle to learn. Haven't had a problem since.

You need to get the datalogit (me too) so you can just reload the map.

I have the datalogit.
So after I reset the PFC, how do I let the PFC "learn" all the idle settings? I'm guessing that I just let the car idle for a while with the a/c both on and off until the idle smoothes out. Then, I re-upload the maps right? Correct me if I'm wrong.

To keep the car cooler, I did this at like 1am with the hood up.
Then you can just reload your maps. Are you using David's maps? If so, the idle speeds will be changed a little bit from the defaults.

It seems excessive but after I did this (after actually following the manual's instructions), idle stability has been good.

BTW, My neighbors would hire a hit man if I did mine at 1AM.
