MAP pressure seems incorrect at WOT
Posted: Tue Feb 05, 2019 11:58 am
What factors affect MAP pressure at wide open throttle? Looking at my datalog, my MAP reading hangs around -1.1 at high rpm, shouldn't it be closer to 0? Am I losing power since it's not as close to 0? If someone could give me all the factors that affect MAP pressure, I would greatly appreciate it!
I have a 2012 Civic Si, with intake and 3 inch full exhaust. I have a silencer on the exhaust tip, if that affects anything. I have also attached a datalog of a 3rd gear pull to see, if someone could please guide me in the right direction!
