09 MS3 WOT AFRs

Post by Enki »

So, uh, I'm running the same MAFCAL I was on AP (actually a bit richer now) and it seems I'm hitting my AFR targets...with meth enabled (initial calibration did NOT have it enabled).

So, just spitballing here, but did you guys manage to transplant WOT AFR trimming into genwon from genpu? If so, that's cool and all but I'll need to make some adjustments to the tune/targets...

:?

As far as I remember the versatuner implements the WOT maf learning based on STFTs both for the US spec and non US cars. The Euro/UK had this from the factory, the US cars did not, and versatuner implements this for them as well.

Otherwise the genpu and genwon MAF CALs should be the same even though you may see a little fuel trim variation between the two under similar conditions (same intake, same gas, same place).

Thanks for this info. Time to dial back my AFRs a bit, since I wasn't trying to compensate for running WMI.
