Hi team, i have just attempted to use the an input from the AFM for an external 4 bar map sensor and am having a bit of trouble with the pressure differential. Im currently reading 243kpa, 142kpa above the BAP. The map sensor is an EFI Hardware 4 bar map, standard 3 pin job. Have i done something wrong wiring wise here? I have got a pin out of the wiring and used 3 of the 4 AFM wires. Any help is greatly appreciated.
