I have problems after installing the greddy. I know other people had the same problems, but after searching i still cannot find a simple right awnser to the problems.
Major issue is when the car is swiching from closed loop to open loop, and when it tries to hold the closed loop. When i am starting, at low rpm, the car shakes, hesitates, alot! You cant drive slow, you have to force it to open loop. In open loop, at WOT the car works fine, it has a steady AFR (from 1 to 0.9) no backfireing, steady 0.5 bar of boost.
Also the car is not drivable until it warms up, you cant move at all, like he is not getting any fuel or something. Yesterday, outside it was cold and it was raining, car was warmed up. When i tried to go, the car was NOT DRIVABLE, it would not move at all, only when i press like 60% of trottle. I parked the car in the garage, and after 3 hours, the rain stopped, it was little warmer than before and the car ran normally, with hesitation, but as all the time.


Car has stock cat, stock midpipe, racing beat exaust, had cels before (misfire, too rich and 02 sensor voltage too low)
I have the latest greddy harness, with 3 dongle.

 

Bump..
