im new to the tuning world and i have question about the three bar map sensor. i hooked up the hose on the bottom port alternator side where im reading vacuum. i wasnt reading vacuum before from a different port. my question is its reading 58"hg on haltech at idle. is this normal for haltechs or is there something wrong with it?

 

im sorry its reading -58kpa. i just noticed this on the software. is this normal?

 

Most people in the states set the program mode to imperial rather than metric. Just to make things easy, but a rough conversion shows that -53 kpa at idle is about right.

 

thanks moremazda. i appreciate the fast reply

 

-58 kPa is about 17in/hg.

 

17in/hg is about -8.5psi.

 

1 PSI = 6.9 Kpa

1 Kpa = 0.1450 PSI
