Fuel pressure sensor
Hi guys,
do 04 Mach 1's have a fuel pressure sensor already on the car like the Cobras did? Thinking about getting an aeroforce interceptor gauge and was not sure if I would the sensor kit too? Thanks.

Re: Fuel pressure sensor
There is another thread you posted in about there being a difference between the reading on the interceptor and an analogue gauge I saw?

Re: Fuel pressure sensor
hard to say without seeing the thread. I know there are a lot of PIDs for fuel pressure, some of them are pressure drop, some of them are deltas etc... could be as simple as comparing the wrong PIDs

Re: Fuel pressure sensor
It was this one,
http://www.mach1registry.org/forums/...d.php?t=132095 Where the reading on is 30psi on the mechanical gauge and 40psi on the electrical sensor but both are correct?

Re: Fuel pressure sensor
The reading I am getting seems to be between 39 and 41 any time, ie engine off, engine idle and engine under acceleration.
Really not too sure what I should expect to see with fuel pressure readings, just thought it differ between those 3 states alot more than what it does. Any ideas?

Re: Fuel pressure sensor
would help to know exactly what PID you're reading as there are several fuel pressure related ones and they read different ways for different reasons.

Re: Fuel pressure sensor
Oh OK.
From memory it was just the first fuel pressure one that was in the list. How can I identify it?

Re: Fuel pressure sensor
Go back into setup and tell us what they're calling it
