Questions

Will this work on my after market digital tach?

Asked by: jjkonye
I assume that you are experiencing needle bounce/ issues, yes it will work with any tac Be sure that your tac is grounded independently (attach your ground from the tac directly to the engine block. Do not ground to the chassis. (Everything else in your vehicle is chassis grounded and contributes to RF interference). RF is your major cause of tac problems if you haven’t changed spark plug wires you may need to change them to resistor wires as well, this is also another source of RF interferance.

Will auto meter 9116 work with GM hei and 1973 firebird oem dash tach. Currently tach read high

Asked by: Farmerick
Thank you so much for contacting us. Unfortunately our tach filter is designed to work with AutoMeter gauges. We haven't tested it with any other gauges so I'd be very hesitant to recommend it for use with your OEM tach. Typically this treats bounciness or erratic movements; it is not used for calibration issues which it seems like yours may be exhibiting. Sorry for the bad news.

I have a Bosch Sun Pro Tach that started fine and is now moved up to 3,000 rpm as it's base. Have a Petronics ignition (old school open roadster). A filter was suggested. would this work. Thank you

Hi Rick, thank you so much for contacting us. I'll echo everything Sarg had to say on this. He definitely knows his stuff and I'm in total agreement.
