I am looking for the proper scale and offset for the 3.5 bar map sensor on the datalogit. is anyone here using that same combo???

 

For the GM 3 bar MAP sensor, choose option 2, scale: 41800, offset: 0. Is that the MAP sensor you are asking about?

No i am looking for the AEM 3.5 bar scale.

 

You could take a shot at calibrating it yourself. I did that for my GM MAP today: https://www.rx7club.com/power-fc-forum-47/dumb-but-lucky-gm-map-sensor-tale-406523/. I got lucky that it matched up so well without having to mess with the offset, but I bet you could take a few readings and then do a little math to come up with a scale+offset that works for the AEM MAP sensor.

I didn't know the AEM units existed, but I see that even Summit carries them now. 3.5 and 5.0 bar (!!!) units are available.

Also, if anyone finds this thread looking for GM 3-bar MAP sensor settings, I now recommend option2, scale: 43500, offset: 0.

Up from the dead... anybody have the calibration for a 3.5bar map sensor handy? ...don't have anything to even try and test it with at the moment. Thanks in advance.
