My gf does too!
well, I just bought a FD couple of month ago that had PFC with Steve Kan tuned ECU. Mode is stock twins Full Non-sequencial set up, 3" HKS catback, Apexi air filter. My car has recent AC gas serviced right before I bought this car. I know it is something to do with PFC. I have searched this forum to play around setting with PFC, but I had hard time finding any info about it.

Right now when I turn on the AC, it sometimes blows cold air for a while then warm air cruising on highway in 5th gear. In neutral and other 1,2,3,and 4th gears it idles pretty funny while blowing warm air in hot weather.

I don't really care sweating in the car and driving around, and this will be only time that I will have hard time with AC throughout the whole year. However, I can't really take my girl with to anywhere in this hot weather.

Any suggestions and tips playing around setting with PFC?
Thank you

 

SEARCH here for A/C problems.


Convert the R12 fittings to 134 but fill with AUTOCOOL coolant which is better than 12 or 134.

 

I have the same problem. Do you have a FMIC? Also Any info or tricks that you find work for you please pass on.

 

just curious Chuck how long have you been running AUTOCOOL?

 

r12 changed to r134 in 1992 just for your info

 

On my second year and have not even refilled or recheck the pressure and it is still doing great.
