Hi all, I have tried 3 different MAP sensors. No matter what I do the readings show as a (+) value on the display. It should be showing a (-) value here correct? I did hook the map sensor to a hand vacuum pump and it matches the value but its positive which I thought meant boost. I did update the value to show -100 as a minimum and max value is 100. Is there a setting I'm missing or am I completely wrong in thinking that the vacuum value should be negative? Thank you!

attached a picture of the display, key on,engine off.

mods can delete,I figured it out. Thanks!

Will you post your fix as well? Incase anyone else runs into this issue? I battled this myself recently and it whooped me. Ended up swapping the map pigtail and wiring, the 4bar to an oem unit, it shows -2 key on engine off but as soon as it fires it goes -19/20 finally.
