We got a call from Greg Creamer that his tach was acting up. After some investigation we learned the amplitude of the square was 10v and it needs 12v. And this happened when the Racepak datalogger and Autometer tach were joined together. The solution was to design a frequency generator that mimics the tach signal. This produced a 16v square wave and the tach was happy. Having the right tools to get the job done is priceless.
