Pentastar (14 Wrangler) Running Rich in Open Loop First Minute
I'm working on tuning my 2014 wrangler with a Sprintex. I'm getting pretty close but have a few issues to sort through. I'm running VE tables with neural net disabled.
My open-loop AFR's are almost spot on target across the operating range, except for the first minute of run-time.
Even if the engine is hot, if I just restart it then for about a minute it runs super rich in open-loop high throttle states. Clips my wideband out at 10.
It runs and shifts really rough during this time period. After a minute, it goes to normal state and drives great.
I'm not sure what's going on here, I haven't found any parameters that would directly explain this, but I'm just a recreational beginner tuner.
