I suspect the Atmospheric Pressure information is derived from the MAP (manifold pressure sensor)

89420M SU00300419 SENSOR ASSY, AIR PRESSURE

Going on the ECUtek options, non-USDM use the CPC sensor. I guess that USDM use the MAP sensor.

I will only use ecuflash,so maybe I try use the ecuflash fix?

I trying OEM MAP &3BAR MAP

always 126kPa

but other brz &86 & FRS are 101kPa

so I think maybe my ATM sensor broken? or MAP broken?

someone there are other ways?

who ECU PINOUT? maybe I can replace ATM resistance sensor signals?
