Message: [QUOTE="m j, post: 1220314, member: 9848"] at about 35psi (256hz) the MAP sensor output exceeds the range the PCM can read and it rolls back to a zero reading, which is about -30psi. I tested this with a couple of regulators and a shop air source monitoring with TorquePro. after you wrap the MAP it takes a couple of seconds for the PCM to come back to normal. I THINK it has to do with the MAP exceeding 255hz which is FF in hexadecimal and the biggest number that can be put in the 2 locations allotted the PID. but I know nothing about computer stuff.
