ive heard that after installing the PFC you should let the car idle for 20 minutes or something to that account.....apparently there was this whole recommended process.

any info on this??

is there a sort of process i should follow after install or is it purely plug it up and drive?

i will be installing next week up here at altitude in CO (7,258 ASL )

 

I let it idle for about 15 minutes. I don't believe that A'pex recommends anything, but I was concerned because my "Exhaust Temp Warning Indicator" (as A'pex refers to it) came on after I turned the ignition to ON. A'pex claims that this means that there is an abnormal sensor on the car, but I have seen many post that this is normal operation. It goes off after I start the engine, and everything seems to be OK. I checked all the sensor voltages too, but they were within factory specs. Maybe this is a misprint in the manual?

Additionally, it was interesting to watch the system adjust the idle. I believe that when first started, the idle went to about 2000 to 2500 rpm and stayed there. Then over a span of 10-15 minutes it gradually kicked down to about 850. I did modulate the throttle during this period, but it had little or no effect on bringing the idle down any quicker. Didn't seem to be engine temp related.

Since that initial start up, my cars may rev a little, but it will cold idle at around 1100 then slide to about 850 (essentially what mine is programmed to do).

I also noticed that during my first couple days of driving with the Power FC, if I got on it hard, it would have a very unstable idle (bounced around about 500 rpm) when I got off the gas and stopped. I found that if I brought the rpms down slowly, using the transmission to brake, the idle would be rock solid when I came to a stop. I progressed away from this (quickly, a day or three) and now I have no problems with the idle at all (rock solid).

Some of the above may be related to the Power FC needing time to adjust to altitude and application specific parameters.

 

Yo Nic, I can answer all these ?s, tough guy . PM me if you need my phone #...

 

Let the car idle for about 20mins so the Power FC will self learn, that what I did and all is ok.
