MAP is manifold absolute pressure, or vacuum as it used to be called. Reporting MAP is expected, are you saying that you can't get a reading for MAF? Go to the CMNDS screen and enter 0110 into a memory and hit SEND. This should return a reading for MAF.
The scangauge actually requests MAF but I don't know why it wasn't made into a default gauge. Maybe legacy in that in the past few cars reported it but if that was the case FPR probably would've been axed also.
If your vehicle is CANSF, an xgauge for MAF would be:
I think a lot of the A/F xgauges that they list on their site aren't correct, unfortunately.
