Fuel pressure sensor for motec - Perth-WRX.com

ECU gurus i want to get a fuel pressure sensor to hook up to the motec. So if pressure drops for any reason it will tell the motec to shut off the engine.

Anyone know where to get one and rough costings?

defi use a pressure sensor which can tap(screw) into most aftermarket fpr's. a matter of working out how to get the sensor to talk to the ecu.

you should use a differential fuel pressure sensor, which tells you pressure against manifold pressure for absolute fuel pressure reading.

K cheers lads..

stace i will order that sensor i think.. Just plugs straight into the FPR?

How would it be connected to the motec?

Suppliers?

has nothing to to with the pressure regulator,

one tube goes to your fuel line, one to your manifold, the plug goes to your motec.

whoever wires it in for you will know.
