i had one of them, it kept on switching my oil buzzer on. i still think they sent the wrong one, as it switched at 0.6 bar not 1.8, but they were having none of it.... it worked fine for oil pressure gauge but not warning or buzzer, quickly went back to ecp...
Glad to hear it! Mine are working well now, I think I've sorted the interference problem by running the sender wires away from the coil and dizzy and also tightening up the main earth to the gearbox on the car as it was loose I was wondering why it didn't want to start properly sometimes...!
