Hey guys.

Two Questions for your expertise.

1) Map voltage should be what at idle and what at 100% throttle....voltatges would be viewed useing VAFC2?

2) The map sensor harness plug itself, has 3 prongs, shouldn't 2 prongs read 5v with ingition on? or 1 read 5 volts and one read 4 volts?

Thanks guys.

 

this shoul answer all your questions

now where my karma points at

 

"Stock 1.8 bar sensor = 2.85 volts with key on engine off and 4.5xx volts at 10.6 psi. "

So with key on and motor not running voltage should read 2.85?

If I am not boosting, and at WOT the voltage shold read what, either with motor running, or not, either way anyone know the voltage?

 

the map has nothing to do with the throttle, you are thinking TPS.

 

I know, but what I said was confusing.

I meant to say that when car is running and in gear at WOT you are approcaching 0 vacuum. What shold the voltage be then, and what shold it be at idle.

Sorry for the confusion

 

at 0 vacumn it should be 2.85 volts shouldn't it?

 

lol, dunno, thats why I am askin
