How to drive a diesel tacho ?
Hi, Am putting a diesel engine into my Westfield and want the VDO tacho to work. I don't have an ECU and have been advised I could use a LM1815
conditioner board to drive it.Although thought about the EDIS module,but requires coils to be operational. Any advice / suggestions would be greatly
appreciated.
Thanks, mike.

Hi Graeme, Will need to work out how to post pics,but doubt they will be of any help re. my query ? The motor is a 1.7 td Isuzu onto a manta 1.8s
Getrag box, if that helps any ?
Cheers, mike

Edit: i presume its got a mechanical injection pump?
i dont have a tacho yet, but intend to use a magnet on pulley and pushbike style pick up. going into a vapour digidash. might have to introduce some
kind of op-amp if the signal is too weak.
not sure how else to do it. some SVA centres have a vibration sensor to accurately check rpm for noise test, but that sounds expensive....

Pretty sure the Tacho is run from the alternator on an Isuzu engine (corsa/astra/cavalier)

A pint for the gent and a white wine/fruit based drink for the lady. Those are the rules
