I have just placed a larger turbo into my car and was going to tune with a SAFC2 but the larger turbo (GCG ball bearing 450hp turbo) makes the car die at idel!!! the car runs awsome, fuel mixtures are perfect on cruise and on boost, but when the car pulls up to a stop the car won't hold idel and stall.
I have tried everything in the safc2 but it won't fix the problem, my mechanic said it is caused when the throtal is closed shut after the turbo has spooled up. The turbo keeps spinning (ball bearing) and the airflow meter keeps thinking the car needs air and alacates fuel to the car when it doesn't need it, which stalls (flouds) the motor.
The Car will Idel fine then started, just does this when the the car has just come off boost and pulls up to a stop?
Has anyone had this problem??? and know how to fix it with the safc2?
I was told I need to get a computer which uses a Map sensor and lose the airflow meter to fix this problem!!!
I can get a Greddy Emanage with all the goodies which includes the E-01 boost controler (big screentype) , greddy stearing wheel boost switch, wiring harnesses, software for $1350 brand new.
so might tread this path if I can't fix it with the SAFC2! anyone used one of these Greddy emanages on their Skyline r33?????
