Check that you have Jumper J1 fitted on the board this puts a pullup on for the tacho. Note the ECU is not driving the tacho this is from the igniter module.

So the Sweep function will have no impact.

thanks for your reply.

In my car there are no igniter module, but ecu drive directly 2 coils.

In any case there is a tacho signal in oem ecu, but i think is a feedback signal from coils to ecu. Is right? 

Jumper add pullup in my wire to tacho?

Hi, I have a same 1.8L 1995 miata, i have the same problem on the tacho, but jumper fitted, tacho still doesnt work.
Did you pull up any wires to the tacho?
