Hi Dave,
I do in deed. But this is already obsolete.
I was at McKeever today and had the chance to test a different coil. I also have changed the Lamda sensor.
The reason why I was asking was, that I still had the cut offs. I have thought about all the issues I see and decided to reduce the boost pressure.
Guess what, I can go up to 1.1 bar max and have no cut offs anymode. Obviously the garage, who has done the chipping, has done a poor job.
I was told that they have re-mapped the boost to 1.3 aqnd based on this I adjusted the boost pressure.
The only thing I don't understand is, that this only comes up randomly. Sometimes I had no problems at all over the whole day and sometimes I can't drive properly and the overboost kicks in.
Do you know by any chance the default overboost cutoff point on an Impreza?
I also have the feeling that the car is not accelerating normally. It feels a bit tired. I miss the byte when giving full throttle.
Maybe you have another idea?
Let me know. I am happy about any idea.
Cheers
Axel
