Resently i put in a XS power T4 turbo (regret) and i know it'll run crappy until its tunned but it all out stalls when i hit about 3,200rpm i dont know if its because this turbo has more turbo lag then the sequentials so the fuel is just flooding it at that rpm but whenever it hits that it just stalls untel i get off the gas, i cant even ease into it total loss of power.

I was thinking that i just need to get it tuned but i didnt think the bigger turbo with a lot more lag would be able to "stall" i think it might have something to do with my ignition, i resently replaced the trailing coil pack with one out of a FC (regret) but i dont know if the spark comming out is too weak or something, im confused and i need help!
Im getting a Haltech e11 and some other stuff inorder to see if tuning it will fix it but if its something else someones came across let me kno

what does the boost gauge say? does it cut off at a specific boost or specific rpm every time?

1st check your MAP sensor connector and hose - make sure it didn't pop off.

Reset your ECU. NOT THE MAPS, just a normal reset by disconnecting the battery.

sounds like an ecu issue. was the ecu configured correctly for the secondary injectors? The secondaries come online at around 3k rpm. If they don't then you are definetly going to run into stalling problems.


EDIT: I dunno why I assumed you were running a power fc. what ecu are you running?

It sounds like he's still running the stock ecu....

stock ecu with a t04e? thats not gonna work

DriftTrix

i kno it wont work, im not trying to drive it around, i just never heard of all out stalling with a bigger turbo, yeah running real bad but not just die, meh, it doesnt get under anyboost at all by the time it stalls nearly gets there stalls on 0, im not driving it, just waiting for the haltech to come in

DriftTrix

thanx for the help so far, i think it might be the FC trailing coil i put in, its diffenetly not the same and if their kicking in wrong that might cause it, thanx fallin

Ok, if it stalls right when it gets to zero, then the ecu is running in limp mode. What this means it that it cuts fuel at any sign of positive pressure. You can get around this by resetting your ecu - use the trip meter to verify that it has been reset.

This will get you driving again, but please do not get tempted to nail that throttle. The stock maps cannot provide the fuel for that boost and you will blow your apex seals before you even have a chance to look at your boost gauge.

it's the ECU - it won't run the engine with aftermarket turbos, etc.

Wait until you have the Haltech installed to drive anymore

DriftTrix

yeah, im not dumb enough yet to stomp it with the stock ecu ill see what happens after i get the haltech

rynberg

What injectors are you running? Assuming you have larger injectors (I certainly hope so), the car could be flooding out when the larger secondaries are coming online.

Sorry, but it sounds like you don't have much of a clue as to what you are doing. If you were getting a Haltech, which requires all new engine wiring, why wouldn't you have installed it when the car was all apart instead of after getting it all back together again? It just doesn't make any sense.

stock injectors, i wanst going any bigger, i wasnt going to raise the boost, the twins went out so i had to do something and i started out going the cheap way but i found out that doesnt work out, so now im fixing it, yeah i kno i have to rewire the engine
im doing a haltech
twin scroll exaust manifold
2x 38mm tAiL waistgates
Frontmount intercooler
1600cc secondaries (new modified fuel rail for it)
walbro 255 fuel pump

the thing was i didnt know why it would all out stall, im not done with it i know better then that and i couldnt afford to buy it all at once so it was just chillin while i got the rest.. aka project car, its not that i dont know what im doin i just didnt know what that stalling was all about, i never experienced all out power failure for it and i didnt know if it was because of the modified coil for it

does anyone know what the difference between the FC trailing coil and the FD besides the little computer attacted to the bottom? does it work the same or is it computer controlled to switch? thats what i think is wrong with the 3 grand but it could easly be the car flooding itsself when the turbo tries to kick in and has lots more lag then the twins

***my mistake i dont mean the trailing coil, i replaced the leading coil*** i forgot the leading was on the bottom sharring a coil while the trailing had their own coils
