Since the gauge doesnt work is there a way to setup an oil pressure regulator to it to make it work(instead of adding an extra gauge)?

 

Dude I would love to have something like this. As a matter of fact when I read the thread I was thinking it would be another one about why the oil pressure gauge doesn't move but hoping it was someone asking if there was a way to set up and oil pressure regulator that works OR and here is what I think I would really want, have a gauge that measures the amount of oil. I would love this. Didn't the fcs, not sure about the fds, have one of these?

 

i've never heard of anyone changing the dummy guage to a real-time guage, would make an interesting DIY though. You'd need probably an older rotary sensor, plus the means to calibrate the dash dummy guage to measure completely empty and completely full using the stock measurements all ready there (the 10 or so vertical lines.)

 

Well, I have a regulator from my old oil pressure gauge so I can do some playing around this weekend or so and see what I can come up with. I just wasnt sure if anyone had tried or looked into this before. I searched but didnt turn up anything so thats why I just had to ask. I'm not sure about the fcs, I think that they just had a low oil light like the rest of em.

 

The FCs had a single wire oil pressure sensor that actually reported the current oil pressure on the gauge cluster. For example, when you revved at idle the gauge would bounce from 25 to 60 psi and such.

I think the problem with the RX-8 oil pressure gauge (as with many new cars nowadays) is that it was never meant to be an actual gauge. It might not have a stepper motor, and probably runs on an ECU status channel through the CAN bus (ie OP OK and OP NOT OK).

If that's the case, you'd need to run your own sensor and wiring, as well as gut the gauge pod and add your own.

 

actually the sending unit is ok, but it does send to the ecu and the ecu decides what it wants the gauge to say. plain talk--its an on or off switch. but just like Gin said it runs on the ecu..
