The 2006 Si is the first Honda to have a MAF and Acura used MAP's on the RSX's in the past. I don't think that the MAP and MAF sensors were integrated into the ECU programming together before though. This use of both together supposedly gives a more accurate reading of air flow and engine load.

Even so, that doesn't mean that the MAP and MAF use the same control schemes as previous K20 engines. Generally, it can be said that the K20Z3 is just a derivative of the K20A's in the RSX's, but when you get down into them, they are pretty damn different. The '06 Si doesn't just reuse a reflashed version of the RSX Type-S ECU. This is a brand new unit, probably to keep a tighter leash on emissions.

Edit: S2K's use MAF sensors (MAF's are more accurate than MAP's)
