Anyone out there running this map sensor, could you check your wires and tell me which color goes where?

thanx! now i need to know whats what on the gm harness...lol its not as easy as it looks.

 

the map sensor itself has the letters A B and C imprinted on it

A is ground connects to the black/lightblue
B is sensor voltage to the green/yellow
C is the 5v source to the brown/white

im pretty sure A is black, B is green, and C is red..... if its not, its arranged in the order ABC and im sure black is ground, so next to it would be the green/yellow wire, and next would be the brwn and white.

ill check for you tomorrow morning and get back to you if im wrong

B... the middle wire should be white

oh yeah... dont forget to change the PIM settings on the PFC to 41800 offset 0

 

wait a sec, do i need the datalogit? i thought i could just do it with the commander...

the wire harness i got from gm is all white wires. I havent looked at the map sensor itself in a long time but if its all marked then thats all i need.
Thanx

 

My GM harness was all white, too. The sensor itself has A, B, C molded into the plastic.

Scale 41800, Offset 0 was a bit off for me. Not way off, but I wasn't happy with the accuracy of the reading. I think I ended up using 43500, 0 after calibrating it myself, however I recommend searching for some threads (I think mine had "dumb but lucky" in the subject) on the settings. pluto posted some numbers he found that worked well, too. I am not sure if you need the Datalogit or not. I suspect the four sensor "options" differ only in that they have different default scale and offset values, but I'm not 100% sure. Perhaps one of them has 41800, 0 as it's default and that is "close enough" for most intents and purposes.

well, with my recent mishap involving my diff(destroyed it) the map sesor swap seems like the only reasonable "project" I can do...at least it seems easy enough.
Thanx for all the replies very, very helpful!!!

 

yes you do need a datalogit, the PIM settings on the car is for stock for option 1, apexi 1 bar for option 2, apexi 3 bar for option 3, 4, 5

41800 0 offset is the one i used for a while from when Dragon was tuning my car.... when steve kan tuned my car he changed it to 44000 offset 357 ....
