Anybody know why my STFT and LTFT are pulling 100% fuel while the O2 sensors are mostly reading absolute minimum (~60mv). To preface this is an E67 from and 08 atlas 4200, on a completely different engine (2.8L Nissan L28).
I'm using a manual transmission, the stock MAF with a 2.5" feed before it (factory was 3"). I expect the numbers to be quite off, but it seems the fuel trims are doing the exact opposite of what the engine wants.
