Argh! i need help again
 

ok guys im having a little trouble with my fd, it just doesnt seem like its running right, idle on my wideband is 13.4, which im ok with just when im driving it and coming to a stop the thing just drops to 500rpms or just dies and we all know how its a bitch to restart a cold rotary..

im a total newb when it come to this power fc so any help or pointers is welcome. all i know is the my power fc was put into run with the single turbo and it says the injector are 550 and 1200 both at 100%
anyway my mods
single turbo gt35r t4 front mount 550pri 1200sec walboro, blocked off everything, premix, you need me to be more specific just say so

but my motor only has about 200miles and i wanna put on atleast 700 before it gets a actual tune and dynos

so can someone please walk me threw what i need to do to my power fc to tune it a little better then what i got now?

When you say blocked off everything does that mean you do not have an iac valve hooked up? Is your dashpot adjusted correctly? You mention restarting cold so im assuming these problems are happening while the car is warming up? Have you let it reach full operating temp before driving, if so any issues there? If its only during warm up try adjusting your water temp corrections, observe water temp and afr and add fuel to the appropriate box and bring afr's between 12.5-13.0:1 and see if there is any improvement.

You should PM Raymond "arghx" about joining the best PFC tuning group which I started back in 2005.
It explains more about the PFC tuning than any other group, and has the largest collection of data, hints, etc for the PFC.

i played around with it today, i got it to keep a good idle and not drop below 800rpm, the a/f is right around 13.2, but then when i went for a drive, got on it a little and when the wastegate open at 9psi, it hesitated so i got off of it right away, i was looking at the a/f's when it did, where should i start adjusting now?

i also switched out all my spark plugs to all trailing ones for break in because ive read its better, think that had anything to do with it?

Stop boosting your fresh motor until its tuned. You can add some fuel in the injector settings to help the idle or raise the idle in the idle settings until you have someone tune it.

thewird

yes

started the car today, idled good was at 13.3 a/f. When i took the car for a drive it pulled out fine, but when i push the clutch in to come to a stop the rpms drop to 500 for a second then jumps back up to normal idle or stall out.. Car does this when cold and warmed up.

What rpm range should i add fuel to? or how should i go about correcting this? note im still in the break in period so i try to stay light on the throttle.

First check the switch on top of the clutch pedal for proper operation.
Look for it in the FSM.
If it is working, then add more idle air to the TB.

"then add more idle air to the TB"

how is this done?

Air bleed screw under the throttle body, large flat head.

This is a reason for you to joing the PFC tuning yahoo group.
It has a complete TB setup guide.

PM arghx if you really want to learn how to tune/adjust your engine.
Or download the FSM as it hass this also but to a lesser amount.

basically, the main ways to fix an idle stumbling/surging/sticking problem are to

1) adjust the throttlebody air bleeds screw
2) adjust the dashpot on the throttlebody
3) adjust the target idle speeds in the PFC (depending how you have your idle set up)
4) adjust the fuel cut recovery speeds in the PFC

^^thanks for the help!

car is running good, turned out my wideband sensor went bad. my actual a/f was 12.4 at idle

Idle still drops after i get off the skinny..i tired adjusting the air bleed but not difference. Im going to try the dashpot next

i finally did it! big thanks for everyone i bothered
