    Tach does not work with MSD in my 67 911

    I upgraded my Permatunes for MSDs and as expected the tach does not work. I have twin plug ignition with switches to isolate each MSD and am using the tach trigger wire from one MSD.

    What is the most typical work-around that has been developed for this.

    Thanks!!!!!!!!

    Paul, I would contact Bob Ashlock, I think his 'tach adapt' might solve your problem.

    Possibly, I thought there was another, domestic work around.
