AEM 5 Bar map and other issue..

[motrmaniac]

alright well i would connect the laptop.. and with key on it would say engine load 37.0 psiand if i flooor the car(car still off) and reach 100%throttle the engine load would reach 67psi why does it do this? I tested voltage at the clip it is 4.98 should be 5.00v but 4.98v seems fine.. when i connect the 5bar aem map it drops to 1.08v.. so i decided to try another aem 5bar map i plug it in the voltage is 3.08v.. The map sensor that showed 3.08v came out of a running car so obv im having a electrical issue but does anyone have input?

My first suggestion would be to update your profile modification list so we can see what software your using and other mods you have done to the car. What did you wire your MAP sensor into to log, it sounds like you've got it wired up incorrectly and getting an inaccurate reading because of it. Heres a write-up on a MAP sensor install using the wiring off the stock MDP sensor.
