Fair enough Nick, not personally come across a 5v one, im sure that will still be fine for Spikey though even if he does have that instead as he'll be able to set the ECU to use that too.
Dont forget the voltage is dictated by the ecu not the sensor though, so I think you may have the wrong end of the stick.
