Electronic Switch Panel

Many high quality fuel injection, ignition, and data acquisitions systems are available for use in race vehicles today, but little development has been done in the area of vehicle control units. For this reason, Portatree and Moroso would like to introduce the Electronic Switch Panel, a vehicle control unit capable of monitoring and controlling up to 10 circuits in a race car. The system consists of the Switch Panel and Main Control Unit (MCU), which communicate through a single cable, thereby, eliminating the need for complicated wiring. Software is available for configuring and testing the Electronic Switch Panel; however, it is not necessary for basic device operation.


  • Allows users to quickly adapt the unit to their needs without re-wiring.
  • Improves over conventional panels by monitoring and recording the amperage draw of its circuits as well as the voltage, oil pressure, fuel pressure, and water temperature. Uses these values to make real-time decisions regarding vehicle operation.
  • With the software, able to detect and respond to dangerous conditions before the user is even aware of the problem.
  • Consists of 4 single-position and 2 dual-position switches that are factory programmed to operate the 10 circuits of the Main Control Unit.
  • Bi-color LEDs display the system state to the user. Solid green indicates proper circuit operation, while solid red and fast flashing red indicate that a circuit has been shut down due to a hardware failure or a short circuit, respectively. When a Master Kill Switch is pressed, all LEDs become solid red and all circuits are shut down. With software, additional LED warning modes can be enabled.
  • MCU can be mounted up to 40 ft from the Switch Panel allowing it to be placed in an optimal location for wiring.
  • MCU contains bi-color LEDs to indicate the state of each circuit.
  • Fuses and USB connector for the system are both accessible on the MCU board as well as an input terminal for RPM and sensor signals.
  • Master Kill Switch, Data Acquisition Switch, Neutral Safety Switch, Transbrake/Two-Step, Wide Open Throttle Switch, and Idle Throttle Signal have input terminals on both the Switch Panel and the MCU for ease of wiring.
  • With Level 1 registration, a user can modify the amperage warning levels for each circuit to better suit their vehicle. This level also allows the user to select which switch controls a particular circuit and enables live amperage test. This allows the user to monitor the current draw of each circuit.
  • With Level 2 registration, enables circuit shut down features. This level causes the Electronic Switch Panel to monitor sensors and shut down selected circuits when sensors are out of tolerance.
  • With Level 3 registration, Data acquisition capabilities are provided.
