But theres no coil.

[slighty_sykotic]

and that is true.....


Umm, surly there is a tmiing signal of some sorts.

Whats the car? Checked the ecu pinouts for the motor?

Does it use a cam angle sensor? if so, what type?

Its an r31 skyline with a 3 litre diesel.

Not sure about what you ask but will check sometime in the next week, Car is at home and I'm not so will check when I get back.

There is a Diesil tacho interface available to run a wire out of the alternator into the interface and out to a tacho.

They are only as accurate as you calibrate it to be,
so to be really accurate you need to get them set of a proper diesil tacho ( that runs off pressure pulses in the fuel line)
or an optical tacho.

So
Q. In a diesel, is it even possible with a normal tacho?
A. Yes but expensive and difficult.
