got the car running good and all but I cant figure this one out.
code vers 3.2.1 on the base tune supplied by Matt Cramer for the Probe gt ZE they have in the shop.
I tried another map sensor mpx4250
D19 shows 5v on one side and 0v on the other
voltage at AD0-1 on the stim is 1.64v
with 18" of vacuum applied via a vacuum pump i get .445v
with car running I can only get ~14.5" of vacuum
tried the calibration menu and in order to get it to "0" vacuum it will also drop the kpa below my normal altitude of mid 90's
