over-rev buzzer
« on: February 19, 2014, 08:03:51 AM »
Ok so I followed the directions (see link) and adjusted the trim pot to the resistance's shown (kinda) as adjusting the A-B effects the other B-C setting.  The instructions for testing have you hook it up to your car which is fine & dandy if your ok with redlining a new unbroken in engine.....which I am not.

So any of you techno wizards out there able to bench test this thing with a signal generator?

Maybe you could use somebody else's engine as the signal generator?  Tap into the neg trailing coil wire on another FB?

It's worth noting that the tach on my car was very optimistic.  When it displayed 8,000 RPM, it was only really turning 7,200 RPM, per a recently calibrated Mustang dyno.  That aspect can be adjusted, too --> You are not allowed to view links. Register or Login
