MSII 2.89 code

i'm useing MSII attached MPX4250 MAP-sensor.
2-point barometric correction, should i use :"147 and -47" or "10 and 260" values

best regards

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.

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
