Okay, so i looked an could not find the info i was trying to find.


What happens to the map sensor's voltage under boost? I just hooked up my new map sensor an getting ready for a dyno pull next week with my tuner.

Also, what should the voltage be at WOT, an just at idel? Any info helps!

also, how do i go about converting the value 760mmhg, witch is what my vafc mesures the mercury in, to PSI?


Can someone hook me up with a easy math, step by step? I hear its not that hard to do, i just suck at math.

All i know is this...

1.0kg/cm2

760mmhg= 1 bar.

1 bar=14.7 psi


thanks again for reading, any info helps me out! Pretty much im just trying to figure out what happens to my Voltage under boost. And also how to convert the PRS value from the vafc. So i can compare the to psi an see how close it is.

An to make sure my ecu is retarding timing under boost.

Your tuner should have the answer to most of your questions!!

It should be 1.826 volts at standard atmospheric pressure.

cool man thanks! yeah i know that my tuner knows it all, but i dont so im fishin for info yo!

He dose not really talk much lol just dose his thing an takes money haha but a good job he dose.

Anyways, He will charge me extra if he has to truble shoot, so im doin that to save money bro.

Is the voltage different with a motorolla map sensor from a stock?


Also, I was reading about the Prs reading on my car. An it never goes into + numbers, at 6.5psi th PRS reads -34mmhg . I thought it should be positive sense its turbo.

any info helps me out alot, Thanks for reading!

bump for info! i know tuners read these post's!
