GM 3 bar map sensor settings off?

[forcefed86]

Just installed a new external GM 3 bar map sensor. (was using internal 2.5 map). Using the MS3 supplied sensor settings for this sensor. I’m Seeing 108kpa with the eng not running. Shouldn't this be 100kpa or right around there? The sensor is working fine with the car running, just skewed a bit. Is it better to ignore this and just tune around it? Or to play with the 0v and 5v sensor calibrations and try to get it to read 100kpa. (I’m at 1300ft above sea level). How do I know if I should raise or lower the value? And which value should I change?

Or will this just make things less accurate across the board?

That isn't a huge offset, you should be able to tune around that but if it bothers you go ahead and play with the calibration. I show your "normal" baro to be around 95-96 KPa so it's reading 12 KPa high, try subtracting 12 from the 0 volt and 5 volt calibration values. You're not making anything less sensitive, just sliding the calibration line over a little.

I'll give it a shot thanks...

Did you change the calibration under the tools menu for the new sensor?

Sure did...
