Hey guys I'm having an issue with my cars idle and I'm posting a picture of my Powerfc IDLE/REV screen and wanting you guys to post the same if you have similar setup so I can see if everything is setup right.

Those ac recover values are certainly not correct..ie. the two values that are 9999rpm right now

They are suppose to be around 1000rpm....Maybe some one with a 25det pfc would be able to give you the default values although i think this would not affect idle directly.

Did they perform the idle learn proceedure on the pfc at installation?

I would set as:

1100

1150

900

950

The 2nd and 4th values are for the A/C.. the 1st and 2nd are for the fuel recovery points. I found out if you're not using a BOV lower values tend to be better.

If you're having idle issues, I suggest hooking up a wideband and seeing that your A/F are.

whats the issue with idle?

those FC cut idles are for the PRO version so they are OK

[gL3nJaMiN88]

Yeh the 2nd value down is for launch control and the one under that no idea

[paulr33]

fuel cut recovery RPM

one is elec load on and elec load off

the first FC cut is pro launch control RPM though

again

whats the problem with your idle

what happens

what doesnt happen that you are expecting

when did it change or last work

[gL3nJaMiN88]

It has never been good from the word go always hunts and when u Give it a rev it stalls then takes ages to start again followed by massive hunting issues

[75coupe]

is it set to the right afm?

Have you had a tuner look at it?

Have you search for 'idle hunting' issue on SAU?

Have you checked & cleaned AAC valve?

is the AFM working? is it plugged in?

and of course everyones favourite do you have an atmo bov? not that mine causes me any problems...

Could be lots of things, good place to start is to maybe search for idle hunting on SAU forums

[paulr33]

before doing any of that who installed the powerfc and did you follow the install instructions

there is a set 30 min idle procedure you must run

if you dont do it properly or skip it

the car will basically instant stall or stall when revved
