Hi Guys,

I can't figure out this one.
My car is cutting fuel on decel. Over run fuel cut is turned off, and AE looks like this.




What else can cause fuel cut?
Also added a little log below.

Thanks,

 

It's not cutting fuel. PW never drops.

I'm guessing you think it's cutting fuel because AFR pegs lean. You have something else going on. Deadtimes configured correctly? VE may be to low for the load.

EDIT: Make certain you don't have any exhaust leaks before the O2 sensor.

 

10-30 kpa rows have the same VE values, so that should not cause the problem.
Deadtimes are correct, I know that for sure.

I will check the exhaust leak option, thank you.
