hello,
I have a R33 GTST with nistune z32 conversion in it and am having problems with getting anything more then 9 AFR. I have verified my wide band is good by reconnecting the narrow and both read the same perameters. In nistune i was told a simple change in the k constant should do the trick and even had them send me a base tune for z32 maf and 740cc nismo injectors and still it runs the same. Im at a loss went to the only tuner out here and they dont want to do nistune as he has never done it before. car ran fine before the nistune and other add ons. I will add what has been done. When the car runs it gets to about 12-13AFR on load and on full boost it will go down to 9 but just sitting it runs so rich and smells strong and even a little gas comes out now my oil is saturated with alot of fuel so i will be changing that as well. I know i read that i shouldnt need a FPR so any help would be great.
