R32 Rb25det Keeps Stalling

[rad100]

well i have just put a s2 rb25det into my 1993 r32 gtst...

mods:

apexi turbo

z32

power fc

splitfires

nismo 555cc

metal intake pipe with BOV return lines removed.

3inch turbo back

eboost

fmic

catch can

now it has been tuned abd makes 250rwkw on 15psi.

everytime i clutch in the revs die and the car turns off..

we pressure tested the whole system and found a leaking plenum gasket so replaced that and still stalling.

there are no other leaks in piping etc..

any ideas on what i can look out for?

cheers

sounds simple, but you don't have a Vent to atmosphere BOV do you?

[rad100]

yeh my stock BOV is blocked off..

and the bov return lines removed and a single metal intake pipe made up!

should i put the stock intake pipe in with the return lines and c how we go?

[The Mafia]

well, when I blocked up my stock BOV the car started stalling as if i had vent to atmosphere one on.

I couldn't fit it. Was really weird, so I just installed the stock one (with return line) on again and its fine.

[rad100]

ah k... sweet...

ill do that!

thanks...

Also try all those vacuum lines.

I had a similar problem, even with a atmo bov.

AAC valve clean?

[rad100]

wats aac valve clean??

[bish33]

yea i would say its ur stock ecu, they sometimes dont like stock bov blocked off or a/m bov. Just plumb the stock one bak in or if u really want the flutter buy a power fc

[joeyjoejoejuniorshabadoo]

he has a pfc...

i would say if you really want the flutterz buy a vl

or put your afm in the cooler piping

hey mate i got a power fc... lol..

i dont really want the flutter but i got a metal intake pipe made up so thats y the bov return lines are removed..

wats the aac?

[and3_3]

AAC stands for Auxiliary air control valve, its what keeps your engine running when not using any throttle.

hey yea sorry my bad lol read straight past it

You've got a PFC, get it tuned properly for idle. It probably needs a bit more ignition timing below 750 rpm.

[chinii]

get rid of the metal intake pipe... i put my standard intake pipe and it doesnt stall anymore =D !

[~Nvied~]

I would say it would be the power fc. First of all what power fc are you using (d-jetro?) seeing as you have a afm im guessing you have the older one. I have a similar problem with mine. Atm making 400hp with the pfc and it drops idle alot when i put clutch in but doesnt stall. Any ive been told its coz of the pfc running a afm. Recommended to change the ecu or maybe try move afm a bit further from turbo as this will decrease the back pressure that the turbo gives off when you come off throttle.

[R31Nismoid]

^ it is not the PFC's fault. Simple as that.

[~Nvied~]

??? If it is the afm that's causing the stall than infact it would be. As the older version doesnt not have a map and relys on the data from the afm to keep the engine idling correctly. That's y the d-jetro version and all dont run the afm anymore due to this issue of back pressure and the pfc stalling the engine.

[R31Nismoid]

Ok believe me or not - im telling you it is not the ECU.

l-jetro and d-jetro are two different versions - one does not superseed the other.

What you were told, was wrong. I've run AFM's on 370rwkw setups, no idle/stalling or otherwise if your tuner actually has a clue

Sounds like you were fed b/s just to have a new ECU put in due to either the tuner making money, or to hide the fact they do not know what to do.
