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.

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?

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.

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.

??? 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.

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.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
