ECU Probelms

Sallain · 02-15-2019, 10:28 AM

Hi 370z forums. After getting my ecu unbricked by uprev , i installed it back in. Once installed I have been having a lot of problems. My car is in a limp mode/safe mode. Doesn't Rev past 3500 Rpm's every time i change a gear (Automatic) , the car jerks pretty hard. Took it to the dealership they stated it was my crankshaft position sensor that was causing the problem. I replaced that and still was doing the same thing. Went back and they said my whole timing is off , that my ECU isn't really communicating with my engine. Issue's are as follows

1. Found multiple issues regarding timing
2. Found intake and Exhaust timing not working
3. Found timing to be to Adavanced on Data Monitor

Pictures of the report/Error copes using the uprev Datalogging - https://imgur.com/a/uTNlGp9

Any Help is Greatly Appreciated! Trying to flash it back to stock , but I do not have the stock Rom's. Tried searching for it , using the uprev website , says not supported

Location isn't much of an issue as long as I can ship you hardware. When I have free cycles I don't mind providing assistance especially to the men and women that serve our country, thank you!
