Hey guys,
I'm trying to clean up the email tune that I'm currently running and I'm a bit confused. I did a quick log while running some errands around town to try to clean up the tune in the areas that I'm not in boost. I'm logging my AEM wideband through the EGR channel with some custom math. My WB02 reading is staying pretty solid around 1 (lambda reading) but my MAF error histogram is showing readings as rich as -14. Can anybody take a look my log and tune to see if I'm doing something wrong? I'd really like to start making some changes to this tune but I don't want to grenade the engine as the truck is my daily driver.
