Anyone who has used an SAFC on a WRX while monitoring a Delta dash can clearly see that MAF input effects ignition advance. The more fuel is removed with the SAFC(less MAF input voltage at the ECU) the more advance ramps up.
I also see less MAF voltage equals less "air flow" (what the ECU thinks), thus shouldnt the natural reaction of the ECU be to advance timing to improve off/low/none boost performance. Wouldnt the ECU think that you're a lower RPM and adjust accordingly?
