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.

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

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

    • Yeah, but the country is turning to a bit of shite at the moment... (Majority of work is NZ'ers, and we have an office in NZ I deal with daily...)
    • If it came off a Skyline you could easily have sold it for $500 to someone wanting OEM parts to return their car to stock. Not sure if that market is in the Stageas or not.
    • It sounds "expensive" when compared to a mass produced tow bar that gets imported from China, but if that's all custom fabrication, then I think where you've ended up, it's a pretty good price! Considering some people will pay thousands of dollars for a few intercooler pipes to be welded up!
    • I think modifying any car, has to be because you like it, OR, you have an end goal to do XYZ. EG, build the fastest VW Golf in the country etc. So, if you're not setting out to do crazy things like break a specific record, or replicate some certain car, then as mentioned above, find the car that you really like, and modify it. Why? Well, modifying any car isn't a sound logical thing to do it. You do it for the fun of it. And if you want it to be fun, you need to start with something you really like. For some, that would be something like an R34 because they saw one in The Fast and The Furious franchise, for others it'll be something entirely different for some other reason. For me personally, why am I here, nearly 20 years later? I loved cars, all cars, and I wanted a car that drove a certain way, I was about to drop the coin on modifying a VR Commodore (Because I grew up in a family that taught me Commodores were the only cars worth owning). And just before I did that, a friend handed me the keys to an R33 GTST he'd just bought that was pretty much bone stock, it drove EXACTLY how I wanted a car to. Nice handling, the right amount of straight line zoom zooms, and hell, I loved the way it looked. I looked at the R32, it wasn't for me, I looked at the R34, it wasn't quite for me either, mainly because they were too expensive  Price is also why I never bought a GTR back in the day. But I loved the curves of the R33 GTST, interior suited me over the R32, and wambam, thank you ma'am! I bought one. And in the essence of "return on investment" and "Sound financial planning", I've been making the dumbest mistakes ever since. Also, I know of a specific mortgage broker on these forums who has a very well modified R33 GTST making great power for the street and track... Then you could modify it with adding a Samsonas gearbox, Bosch motorsport ABS system, and go have some sick fun! Oh, and then you'll be able to help him get me my next mortgage, because that, like modifying a car, is probably a stupid financial decision for me at this moment the property I want...
    • It cost me $2900 all up for a local trailer / towbar place to supply and install. I did think it was a bit steep initially but after all the work involved and seeing the final result I think its well justified.  Hardest part was finding someone willing to customize and fit it up with trial and error basically. Whereabouts are you located? - I had my work done locally in Wangara.
