Hey everyone-

I bought a new GM 3BAR MAP sensor that I want to install this weekend. I also got a generic GM plug, which is pig-tailed, which I intend to solder into the OEM harness (cut OEM clip off harness, and solder harness to new GM MAP clip).

Here is the unit I bought:


In the picture above, from left-to-right (PIN 1, PIN 2, and PIN 3) on the plug receptor that is on the sensor, which is the positive in, map lead, and ground?

I have an OEM manual, so I can find out which is which on our stock harness, but its just a matter of what PIN on the GM harness to solder the wire to....

Thanks again!

John

Thank you much! Exactly what I was looking for!

timg - Seeing as you know about AEM too... I know that the GM MAP sensor is already pre-calibrated within the EMS as an option. Where is the menu to change from the OEM MAP to the GM MAP? I want to say I saw it when my tuner last looked at the car about 6 months ago, but I am not 100% sure where it was located... I want to have everything lined up to go when I get to cutting...

Thanks again, man!

Wait, that Hondata link says that a 3-bar can read up to 28 psi... What the? One bar is equal to 17 psi. so simple math tells me... Umm... not adding up here....

 

1bar is 14.5-14.7psi

 

Ok, I stand corrected... But that still translates to 2 bar, not 3!

 

NA sea level pressure is 1 BAR. 2 more BAR in top of that = 28-30psi.

Awesome! Going to install this bad boy and my electronic boost controller tomorrow.

Going to a dyno day on Nov. 22 here in town. I hope to be at 400+ by then!

I've been a slacker.
