I have a banging problem with my RST..And I want to learn something..

1- What controls the boost on idle? Because I have 11 psi boost at idle.. I cant prevent it.. overfueling can do it?
2- I have banging at hard accelerating.. what does this?

Thanks for the help..

The car's specification..

1-13 psi boosted
2- PTS chipped ECU
3- Big intercooler..

 

You certainly DO NOT have 11 psi at idle. Unless you have a WRC car. It's just not possible for the turbo to produce 11 psi at under 1000rpm engine speed.

More likely is that your boost gauge is stuck.

The banging could be any one of a number of things. Spark blowing out? Fuel cut?

 

Sorry for my English..

I have 11 psi at 5000-5500 while reving at idle.

I cancelled the fuel pump relay and bridged it... But the car goes well before.. it can affect something?

 

1- I have boost on accelerating at idle while hard reving car..
2- When it is boosting, it is banging..
3- I changed dizzy, Fuel and Ignition ECU, spark plugs, cables, Fuel pressure regulator but no change...
4- The Rev Cutter is not working. Car is passing 6250...Why?
5- When stand by the car the fuel pump is on.. Can it affect anything?
6- How can I understand the fuel setup is correct?

I have suffering from banging problem about 2 months.. I will be mad.. Please help.. I want all advices..

 

yeah hi,waste gate actuator and amal valve should be checked when it comes to BOOST,adjust accordingly,ok,thanx???
