Re: MAP sensor - 2-point baro correction
WASyl,
The '10 & 260' values are for calibrating the overall MAP sensor response (i.e. the MAP level assigned to a given voltage from the sensor). You use these under 'Tools/Sensor Calibration' but ONLY if you have a second baro sensor. It sounds like you don't have a second sensor. There is more here: http://www.megamanual.com/ms2/configure.htm#altitude
The '147 and -47' values are for barometric correction, these adjust the fuel based on the current baro value, and I think this is what you want. There is more here: http://www.megamanual.com/mt28.htm#sb
