Apexi Decs Tacho Install

[elysium]

Has anyone had experience with one of these tacho's? I've installed it, now trying to setup the cylinders and warning for oil pressure and water temp.

It's constantly beeping showing OP on the display, it did this as soon as it got power. I'm taking a guess this is the warning for Oil pressure, I've tested connecting the oil pressure sensor and also have a separate gauge which shows the pressure is fine, but still the warning is going off.

I do have the manual and have followed it, but it seems as though it's not accepting the inputs as I'd expect it to. I've also set the cylinders to 6 but it's still showing the revs too high. Is there a way to reset these and start from factory default settings?

cheers for the reply, that one does seem to go into a little more detail than the manual I have. Will give it another go.
