I just installed my power fc, along with a bunch of other stuff (that u could see in the list below)... Anyway, i turned it on for the first time and it idles at almost 2000 rpm.. i hit that gas a little to stop it from warming up that cat, and before it used to go down to normal but now it just sits at 2000rpm and its a little jumpy too?? Anyone ever had this problem before??

I bought the PFC of a guy who had it tuned to mods similar to mine and i even compared the map on the pfc to another map off the internet and they dont seem to be that much different..?

Any suggestions, thanks for the help...

The PFC must LEARN to idle your car . If your throttle body is set correctly then the PFC will take some time to LEARN ,it may take a week of driving or a day.

Sounds more like a vacuum leak, It is not always noticeable with a stock ecu when small as the ecu can compensate for it, but when installing a power fc it cannot compensate so you will notice high rpm idle and erratic idle.

My power FC defaults to 2 grand until it warms up. And you can't just tap the gas to kill it. Once it hits about 100 it drops to 1500 and then finaly to 750.

I don't have a commander so I can't change this yet. The next time I go see my tuner I'm gonna have him disable it.

But yea, mine does the same thing till its warm.
