[QUOTE="WDW MKR, post: 3459559, member: 8038"] Tuning your STFTs builds your MAF transfer function, from which everything else is based. If you MAF TF is off, it doesn't matter what A/F you command at WOT... it won't be working from the correct base numbers. The reason I said it is tricky to datalog at particular MAF counts is that they are harder to keep steady than RPM, making it easier to lose your frame of reference. You may be looking a MAF counts thinking the engine is screaming, only to look at RPM and see it at 2500. When you go to look back at MAF counts, your foot has moved and the numbers are different. It helps if you can display RPM and MAF counts right on top of each other. I think this is possible with my Raptor, but I'm not sure about using the XCal2 display screen. [/QUOTE]
