Preventing RF / EM Interference with Progressive Controller
Typical Progressive Controller RF / EM Interference Symptom
If your progressive controller’s active display flashes on and off or resets itself during operation causing the vehicle to
surge, it may be caused by electromagnetic interference generated by the engine’s ignition system or other vehicle
components.
RFI / EMI Controller Backing Plate
RF / EM interference can be reduced by using a 3/16” or thicker plate to cover the rear face of the controller. Plate
and housing surfaces must be flat sanded to assure a tight fit; no sealant should be applied to surfaces. This backing
plate can be fabricated with basic shop tools and is also available by contacting our technical support department.
Controller Mounting
Do not mount the progressive controller anywhere near ignition components or any other source of electronic noise.
If you have difficulty isolating the controller from RF / EM interference, it may help to mount the controller in the rear
portion of the interior as far from the firewall, ignition components, and wiring harnesses as possible. Controller
should be mounted on flexible rubber mounts or Velcro to assure the housing is not in contact with the vehicle chassis
or other common ground plane.
V
ehicle Wiring
Edelbrock recommends using a DVOM (digital volt ohm meter) to test resistance between all ground points and battery
negative terminal. Anything over 1 ohm of resistance is a bad ground and must be corrected for proper operation.
