So my car has no codes and it is a new built 440ci engine with a decent cam. motor and was broken in on engine dyno first.
Map sensor was put on by the shop and they used a sensor from a Z28 7.0L Camaro according to part number. My car is an 07 Z06
Max kpa where I live is 99kpa as shows by baro app on phone. Also previous stock block H/C/I combo would show 98-100kpa at wot depending on weather and exactly where I was driving.
Right now it is showing no more than 84kpa key on engine off. Idle kpa is around 56ish but I did advance EOIT ECT table by 15deg to see if rich idle smell cleared up at all.
I unplugged the MAP and turned power on and checked voltage at the prong inside the plug with multimeter and saw 4.98v.
Is it just that the MAP sensor is for a different ECU causing it?
I can't see a vacuum leak or anything engine related being the issue since it reads low with Key on engine off. I took the sensor out to see if was damaged or blocked up and it looked fine. IT read 84kpa just sitting in the open air as well.
I just do not know if anything in the tune could have been altered to cause the kpa to read differently.
Car runs fine otherwise but does have some surging under 2000rpm when cruising.
