Map trace follows only one path
I just got my b13RT 2 weeks ago. I tried tuning using Nissan Datascan and TunerPro RT. The base tune from Calum is OK, but when I trace the fuel using Datascan it just follows one diagonal path from corner to corner. It doesn't matter what the load is, it alway follows a linear diagonal path. I'll try to get a screen shot up later, but I know its not normal.
The trace stays on that path when I let off the accelerator(instead of shifting over to the left most column for TP), the computer still dumps fuel as if the engine is still under load. When I shift, it always backfires and actually blew the gasket on the turbo and by the cat.
I tried changing the MAF for another one and same problem.
Any theories why this is happening?
