R34 Dose, And Bov Block Off

[fruitymash]

hey guys got abit of a problem

this morning i put a new 3 inch intake arm on

blocked off the bov

dont worry i got pics

now theres a small hose which i believe is going from the top of the boost solanoid (correct me if im wrong sorry for the silly questions)

and that use to run to the old intake piping

now my dillema is the car stalls if i do sudden stops i got to ease it in, and im getting a loud pop out of my exhaust when i de-accelerate

would me blocking off this hose that use to run to the intake cause my stalling or is it the excess in back pressure cos i got a stock cat and there after i got 3 to 4 1/2inch catback right behind it causing a bottle neck due to the increase in backpressure and power?

Just remove the whole stock boost solenoid all together and run the hose from the inter-cooler piping to the wastegate.

It shouldn't matter with a stock cat either....im guessing it was fine before you blocked the BOV?

Not sure what that hose does that runs from the boost solenoid to the intake pipe though....I had it on my 180sx and removed it when I removed the stock solenoid.

It could be a build up of pressure inside the intercooler piping thats trying to escape through the turbo and causing the car to stall??

Maybe reset your ECU for it to remap itself as it would be running richer without a BOV

thanks for the input mate

which hose are you talking about ? one i took off the top of the solanoid? (i blocked it off with a bolt in the pic)

sorry for the dimwhit questions

yeah it was popping before but not when de-accelerating and dropping gears

only popped when i was changing gears from 7k rpm

Hmmm....

chyeah got me stumped,

just took it for a run for 30 mins didnt stall once but reduced popping during decelleration but still there

and just stalled in my drive 4 times lol

Your car is stalling because of the BOV being removed, it's a well covered topic mate...

[StealthX]

Why'd you block off the BOV?

[fruitymash]

hahahahah hellzz yeah sututututu

[fruitymash]

quick question anyway

how would i got about resseting the ECU for a remap?

is there a pinhole on the ecu?

cheers

Need Nistune or aftermarket ECU, then a custom tune to tune around the BOV blockoff. Stock ECU expects the compressed air to be otherwise re-circulated through the intake, what is being measured at the AFM and what is actually reaching the engine is why it's stalling and running like crap.

okay sweet thanks mate!

i heard getting a decent tune is around 700 too 900 through nistune but not including the piggyback ECU

either put the stock intake pipe back on or get the stainless pipe altered so you can run the stock bov. even with an aftermarket ecu you are still going to have slight issues with it stalling.
