Im Considering fitting an oil pressure and oil temperature to the Exige, similar to what I did on the Europa. I made an 1/8 NPT boss and welded it into the sump for Temp and pressure made a T piece coming off the pressure switch on the back of the engine.
Are there any sutible locations to put the sensors without having to go to these extremes, or fit a sandwich plate off the oil filter. The car has the twin oil coolers if that helps.
So when it hits a set threshold does the the little red LED flash or the whole display screen changes colour? I am curious how noticable this is compared to installing a lage orange light on the dash top.
You can have either as far as I know, the way I have it set- the backlight itself flashes red (or any colour, could be green/blue/etc). The SPA gauge also has an option to send a signal to an external alarm too -so you could wire it into the stack gauges if you knew the appropriate pin-out so the OEM oil warning light comes on at a custom threshold, or even a buzzer/alarm if you’re that way inclined.
Only issue I find with oil pressure is that after a hot run, if you bring the car back down to idle the car is likely to drop to 1.3-1.5 bar anyway so you can’t set your threshold too high unless you’re happy for the occasional alarm flash at the traffic lights!
