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

what engine are you using? 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....

Most diesels run the tacho from the alternator, just take a tap out before the regulator.
