Early test with low threshold set at 40, high threshold set at 160, best guess figures based on data from Bill from Delicious Tunings SD thread.

First plot is MAF sensor (FFF8D400) vs raw table output (FFF8D404). Values a bit high between 100-225 g/s.

Second plot is MAF sensor vs value compensated for IAT (FFF8D408). Slightly better, but still a bit high between 125-200 g/s and low over 200 g/s.

Third plot is the value for hybrid blended MAF (FFF8D40C). You can see the interpolation working over 40g/s but due to the errors low in the range for this map, would be better having a low threshold at 120 or 160.

This is done in test mode so final figure can be logged and SD map built without actually applying it.
