PostSubject: lean afr not changing   Sun Jul 14, 2013 4:08 pm

I'm running about 1.0 units lean during pulls, according to Target_AFR and Final_AFR1. Increasing my VE in the affected areas doesn't seem to help. The O2Fuel_MultA reads around 1.16 until 4000rpm, then drops down to 1.0 for the rest of the pull.

My fuel pressure seems to be rising 1:1 with the MAP, and my injector duty is increasing linearly as well.

I checked my plugs and they look lean too, so I don't think it's a wideband issue.

It seems like the ProEFI knows I shouldn't be that lean, but isn't adding enough fuel to compensate.

What could be causing this?
