So I just pulled this unit apart, and noted the internal map sensor is rated to 250Kpa, That puts the sensor in the 36psi range, are you saying the sensor cant take more than 22psi, or the programming cant scale past 22 psi? David, thanks we are going to use a MS-pro ecu on the sand rail, this old Link will be retired to running engines on our run-in stand, no boost or load, just thermal cycles and data collection. What would you have to have for that G1V5 unit? I think i really just want to order the new MCU with the later code for PC tuning. But where would I order it?
