Re:MAP sensor difficulties.
Are you joking?Anyways,the gm 3bar is easy to hook up, tie the 3wires from it to stock plug in on the map sensor and and unplug the old one.This would prolly be a good time to run uberdata,I can help you more once you get real fuel managment but I must worn you its not plug and go.My 3bar is a bitch to tune, I finally made it to 10psi with good mpg.Make sure to get a WB, borrowing one from a friend is a bitch. do you have a built motor?

Re:MAP sensor difficulties.
Stock 1.8 bar sensor = 2.85 volts with key on engine off and 4.5xx volts at 10.6 psi.
GM 3bar sensors read ~1.6volts key on / motor off.
what this entails is that your fuel map scaling will be incomprehensibly wrong.
when you are at WOT (0" vacuum) with the 3 bar, your ecu will see 1.6V, which to it means you are still in vacuum.
so basically, without chipping or an ems, a 3 bar is extremely useless.
in simpler terms, you are dumb.
