Hi, After the install of 444cc,z32 and stage 3 chip I got problems with my ca18det.
It got slow gasresponse(1 sec after?) and jump and "brakes" when the boost/load comes. It feels like a intercooler leak. But the thing is then i put my stage 2 chip and original MAF back it goes alittle fat but much much better, but thats cause the 444cc injectors.
I think its running very very rich, black smoke and smelling gas. I've tried to change the engine temperature sensor cause i got a faultcode on that and now my ECU shows 5 red flashes and 5 green (OK)!
The Z32 N62 maf wiring is Okay!
signal - B
ground - C
ECU ground - D
12+ - E

The signnal from the Z32 is around 1.2 - 1.3 on idle, checked to the ecu.
No boost leakage, checked many times.

What can it be? Got right signal from MAF(I think?)
The first 3 seconds when i start the engine the gasresponse is like it should be.

Have any idea what it can be??

Might be the chip itself. It sounds like that chip might not be compatible with what they say it's compatible for.

I've tried 2 types of chip, and one of them on the label it is "Stage 3, Z32, 444cc" and thats a map that many ppl run fine with this things!
