Weird fueling issue.

Post by dj_smooth » Fri May 06, 2016 6:51 am

Having a weird fueling issue. Log and tune are in the link. Could it be that my MAT curve screwed things up during my pull? Fuel pressure regulator seems to be holding fuel fine. Wideband was ran to 10.5 at idle and then the car was killed and I watched the wideband slowly lean out. I adjusted the mat curve to help combat heat soak at idle however during the pull I ran into the flat zone of the mat curve.

Update. The LSU 4.2 sensor was bad. Also changed MAT curve back to ka24de base map value.
