I was able to find the info after some searching on the Yahoo Power FC User Group. Heres the info for anyone wanting to do this. This will allow you to log boost without having to buy the Apex Boost Control kit.


You need a +5v to power up the sensor and ground it as well. You run the signal out of the sensor to the 0-5v input on the datalogit box.

1.58v = 0
4.01v = 22.5
Unit of measure = PSI

This setup is for a GM 3bar map sensor.

Ground on Pin A,
Sensor output on Pin B
+5V ref on Pin C. (commonly sourced from TPS)

Part #12223861

there is also a pigtail with the sensor for a better connection and cleaner install. i couldnt find the GM part # but im sure if you are order from a dealer that takes the map sensor part number, they can easily find the pigtail to match with it.
