    Mapping and Tuning MAF and VE

    Hey there, just wanted to double check with people who know way more than I do about this stuff. Got an 02 S10 4.3l that's been manual swapped, there's some engine mods done like exhaust and CAI, and so I'd like to log the VE and MAF and properly adjust them. I know it's probably not needed but this is mainly just practice for when the bigger mods come. Here's both the Tune's and Both the Logs that I'll be using for it. Lmk if something needs changed, thanks. S10 VE Tuning, MAF Disabled.hpt S10 MAF Tuning, VE Disabled.hpt MAF Tuning, must have VE disabled.Layout.xml VE Tuning, must have MAF disabled.Layout.xml

    Tunes are setup right for the most part. In the MAF tune you forgot to disable DFCO. Also, you have LTFT disabled in VE but enabled in MAF. Set O2 voltage to 451mV.

    I'd adjust PE thresholds for TPS and min MAP in order to grab more CL cells.
