Everything works right on my S-AFC except for the pressure shows -760 mmHG all the time. I don't remember hooking up a cable for a MAP sensor or anything like that and the AFM only measures that (air flow). Is there no way for the S-AFC to read the pressure or is it hooked up wrong? If it needs a sensor is there anyway to add a pressure sensor to the S-AFC? I'd prefer to use the spot in the gauge pod for something else, plus the autometer gauge is ****!!!



...man I wish i would have known how shitty they are befoe I bought it.



Anyhow,



Thanks again.

it's not hooked up to a pressure sensor. therefore you don't see boost. you answered your own question. if you had a car that used a map sensor instead of an AFM (fd etc) then it would show boost instead of air flow.

his car does have a 'boost sensor' which is a 1 bar pressure sensor, you might be able to wire it into the s-afc to get it to display the value.

Shouldn't his car have the 2bar map sensor?
