So Im having an issue with WOT fueling changes...even from one gear to the next....sometimes fuel is within a percent or less, then other wot blasts and the dyn. airflow value changes by a couple percent, and wala, Im lean...(or rich here and there)
I know this has to be a parameter influenced by MAT value, but logs show it only changed a couple deg C from gear to gear in the attached and yet for same maf hz (11600 for ex.) its got different dynamic air values and is pulling lean.
Ive also had very rich hits intermixed, with no direct correlation to ambient temps...though the air is getting dryer...so Im just confused.
Any input is appreciated. My MAF curve needs some smoothing perhaps, but Ive got logs with same airflow model that are tight to commanded, and then swings of a couple percent each way, again with no maj diff in IVT, ITT, or MAT jumping out.
Running an intake with 7:1 honeycomb 3 in in front of MAf with a hard 90 from there to behind fog light...
