Thread: EMI & Dual Sync Distributor

  1. #1

    Default EMI & Dual Sync Distributor

    Has anybody had success overcoming their "noisy" signals from a magnetic pickup by changing over to a Hall-Effect distributor? Are there any other issues one might run across using the Dual Sync Distributor? Also, what should the Minimum Signal Voltage be set to?

    Yes, I have. I've had zero issues using the Dual Sync Distributor. Now Holley has released the HyperSpark distributor that's cheaper, and has a Hall-Effect sensor.

    There's no "Minimum Signal Voltage" & "filtering" parameters with a Hall-Effect sensor/distributor.

    Another problem with using VR Magnetic sensors, is there's more tuning work. Hall-Effect is "set & forget".
    The VR Magnetic Sensor Type "Filtering" & "Minimum Signal Voltage" parameters need to be programmed. (Magnetic Crank/Cam Input Filtering Parameters - Page 2)
