Hi Moshi,

You will want to just select 3 bar map in the pull down menu for the what aux channel it is on. Then go to the Map sensor calibration and calibrate. That should do he trick for the GM 3 bar.

As for the wiring. Have a look at this diagram. This should get you all squared away.

Did you do a Map Sensor calibration and store after selecting the right configuration? If the map sensor is calibrated right it will give you a message saying calibration complete. Or an error message. Maybe you have something adding additional fuel in your tune. Hit R for run time values and look at the fuel section to see if any trims are active. Post a log.

I am sorry I totally failed to look at the part number on the picture. The first three numbers represent weather or not it is 1,2, or 3 bar. You have a 1 bar GM map sensor. The 4 number in the last 4 numbers represents 199* so this was manufactured in 1995. You are looking for #749 part number stamp which will be a GM 3 bar sensor.
