SymTech Labs' 4 bar MegaMAP sensor is capable of interfacing with all MegaSquirt ECU's and reads up to approximately 44psig. It mounts in the same location as the standard 255kPa MAP sensor and includes additional circuitry to constantly measure and correct for ambient barometric pressure. This kit includes the main sensor board, bulkhead fitting and washer, jumper wire, and several inches of connecting hose. A connection to the main MegaSquirt board with the included jumper wire is necessary to utilize the barometric correction feature.

This sensor requires 0.5" or more of clearance between the MegaSquirt board and case.
