Tach signal
Jackbauer,
Would you elaborate more on how you got your tacho to play ball.
I am in a similar position. I retained the original reluctor ring & sensor (multiple pulses) + the ECU expecting that it would keep putting out the usual 12V 2 pulse per rev signal to the tacho.
The ECU is not being very co-operative at the moment & the simpler solution is to drive the tacho directly but I don't know how.
