    I am in the process of installing an AIM MXL dash/datalogger. Tapped into the grey wire with blue tracer coming from C1 (Tach output), but AIM is not seeing any signal. The signal needs to be a square wave, anyone know if that's the case with the RPM signal from the ECU?

    These are my options as per the manual

    from the ECU through a square wave signal (from 8 to 50 V);
    from the coil: low voltage input (from 150 o 450 V).

    Thanks!!

    I vaguely recall this coming up many years ago in regards to shift lights...found a couple of threads that MAY be of interest by searching with "tach signal".

    Sorry for not having a better answer...good hunting.

    yah, I saw those, but besides finding the tach wire they don't really help much.

    Update: got the signal, just needed a filter for the signal (Aim part).
