Car is CRX SI I swapped it with a B20B and car runs great until I go to full throttle I get a Code 3 MAP sensor code and then the car runs like crap. I have to turn the car off and restart it so it will run good again. The engine runs strong as long as I do not go to full throttle. Only upgrades I have on the engine is ITR headers, Skunk 2 Pro series Intake manifold and Throttle body, and 2.75" exhaust.
Things I have checked:
Timing is good ( checked with test light)
Swapped out the MAP with 3 other brand newsensors
TPS is good and calibrated (have tested 3 others I had laying around)
I have 3 ECU's that I have tried. P28 chipped, 2 x P75 virgin
Fuel Pressure 28psi at idle with the vacuum line connected to the FPR and 38psi disconnected
