Having just had an Emerald M3DK fitted we cannot get the Tacho too work. Can anyone tell me where the supply voltage is supposed to run from to engage the rev counter/Tcho please? We are puzzled at the mo. Thanks in anticipation guys.
The usual wire is white/black on pin A4 … thats the tacho signal from the ECU - pin 58 on the Exige ECU
Think it should go to pin 12 on the Emerald
Got the tacho showing revs now but its got a problem between 2-3500rpm. On overun when you back off the accelerator the tachco needdle sometimes drops quickly before returning to the revs it should be showing. Have you any ideas what this could be please? thanks
