Roger Ennis found this in the hi-res code

#elif MPXH6400A 
;   barometer        = { table(baroADC, "kpafactor4250.inc")          } 
   barometer           = { (baroADC + 2.147) * 1.6197783 } 
   map                 = { (mapADC + 2.147) * 1.6197783 }
Which confirms that there is no look up table for the MapDaddy sensor, and gives us the formula that the MS uses to translate ADC to MAP.

I'm going to keep my offset value at 4 because it agrees perfectly with my boost/vac gauge, but for the record, MS uses 2.147 for the scale.
Guess my autometer phantom gauge is off by 1.9kPa. I'll live with it.
