- Adjustable broadcast rates for each channel from 0-100 Hz
Input Examples:
- 12v Toggle Switches such as external mechanical relays or digital switches
- Ground input for a brake pedal switch
- 5v Analog inputs for fuel pressure, oil pressure, or nitrous bottle pressure sensors
- Thermistor inputs for coolant temperature sensors
Output Examples:
- PWM (pulse width modulation) Electronic fan control
- PWM (pulse width modulation) Fuel pump control
- Other PWM (pulse width modulation) controlled devices
Notes:
- HP/Dominator Requires V6 Software version Build 200 and higher. Terminator X requires V2 Software Build 51 and higher.
- Supports user-configured inputs and outputs from the Inputs/Outputs Individual Configuration File.

More Functionality for Your Holley EFI System
Monitoring critical engine conditions and operating vital racing equipment is crucial when it comes to your drag car. Holley's EFI CAN Input & Output Module plugs directly into your HP, Dominator, Terminator X, or Terminator X Max EFI system and adds eight input and output channels to your new or current setup. This module is a must-have when you have exceeded your max inputs/outputs and need additional fuel pressure, oil pressure, or nitrous bottle pressure sensors.
