Hi
I have recently purchased a spa gauge off a member from here, but I'm having some problems with it reading the correct pressure.
I believe the problems come from the voltage the pressure sensor recieves before the car starts. If I turn the key to the last click before starting the gauge fires up and reads -14psi or something, so then when the car is started it reads a false figure.
Now I can zero the sensor and it then works fine, ( I did this at Donington last week) although last night it seems to have forgot.
Just wondering where people have taken the live for the gauge and sensors from and where they earthed them.
Many Thanks
Ash
