I have an R1 engine and a Mychron 3 'digidash' (not the ETB one) and have some alarm LEDs to configure. I was wondering what a sensible PSI value to to set the oil pressure warning light at?

I don't think I have the ability to incorporate RPM into the pressure alarm function, so I guess I will have to have the alarm LED illuminating when the car is at hot idle (ie. when you get worryingly low oil pressures that are normal)?

Also, how about water & oil temps?

Thanks.

If you cant set an X psi @ Y RPM, then I would personally set it at about 20-25psi. This will mean it will always come on at hot idle, but Id rather it do that but know about a real pressure problem with reasonable warning than wait for it to drop to 8-9psi which is what it would need to be at to avoid a hot idle alarm.

Cheers Chris - will go with that suggestion.

How about oil temp?
