hey all,

i'm a little problem with my pfc , at idle it's reading +0.61 hg I think thats 5-7 psi boost . when i plug in another pfc and it reads -0.20hg then the car runs great..
what i'm i doing wrong??

thanks in advance....

 

MAP sensor setting. Are you running the stock MAP sensor? What mods do you have done to the car?

Go to settings --> PIM volt. What is selected?

 

.61" of mercury = 0.299604 psi

 

yes i'm useing stock map. also mod 's are greddy t87 kit , hks twin power, greddy 3row intrecooler , greddy evo2 exhaust, supra fuel pump , stock mazda reman motor 500 mile on it.

 

sounds like you got a premapped EMS that is setup for a different MAP sensor, but even a 3 BAR wouldn't be that off so sounds like someone has been messing around with your unit and the MAP PIM values.. did you try initializing it? you will lose all of any corrections that have been made though so beware.
