Rb25Det Boost Jumping

[89CAL]

I'll translate, because I' in a nice mood

1kg/cm sq is around 1bar

1bar is around 14.7psi

14.7psi > stock boost

thanks mate.

i will take out the boost controller

sorry for f**king with your time then!

for later on just put a new ecu for higher boost .

but to be honest it doesn't feel like it hitting 14 psi but some days it running fine

[wounderz]

wait u saying its running stock boost then why he says the ecu is stuffing up then

[89CAL]

14.7psi > stock boost

IS GREATER THAN

The ECU assumes a problem when it sees more airflow then its expecting so puts the thing into rich/retard so the car wont feel faster

Quite the opposite actually. I ran mine on 10psi when it had stock ECU thinking it was cool. Then one day I turned it back down to 8psi or so and it felt quicker. I put mine on a dyno at 10psi I think and the AFR's were in the mid/low 10:1 which is far to rich

You also said no mods not then you tell us it has a boost controller!

[Ben C34]

Anyway glad it is an easy to fix and cheap problem for you!

[Blackkers]

man, Boost controller means you are not running stock boost!

so what you have to do now is: lower the boost and preferably find a better way of measuring it seeing as you didn't know what it was before.

then if the problem persists come back to us

Good luck

Gap your plugs down to 0.7mm, turn off/disconnect your boost controller, check what turbo you have, if you have a standard turbo then budget for a replacement turbo, if you have an aftermarket one, budget for a new coilpacks + ECU + tune.

Lol.. this thread was a great read... glad I hung in there to make it to the second page.

Wounderz - We all get the shits here when people keep asking the same questions that have been covered 100000 times... All you need to do is search, then to top it all off you don't list your mods and not to be rude but do much about what you are talking about... Its difficult for us to help you when you don't have the basic knowledge.. I get everyone has to start somehwere and learn but start reading the threads and DIY articles..

As said above. remove your boost controller and re-plumb the stock solenoid and see if your bosst stays at a stable 7 SPI... if it does then you can try putting your boost controller in BUT wind down the boost level....

Thats my 2 c....
