ECUMaster PMU-16.

This is the PMU used in the FrogJam Motorsport Clio.

ECUMaster Description:

Race cars now feature advanced engine management systems, antilock brake systems, paddle shifters, dataloggers, radios, electric pumps, fans, and lights. All these components need to be controlled at the correct moment, and all components require circuit protection to prevent damage or fire.

Traditionally, fuses and relays served all of those purposes, but they have many disadvantages like complicated wiring looms, sensitivity to vibration/temperature, and difficult diagnostics. All of these problems can be solved by using intelligent power management units (PMUs).

One of the main advantages of the PMU is continuous current sensing and self-resetting function if the current exceeds a defined level. All output state, voltage, and current information can be logged and transmitted via CAN to dash displays to inform drivers of potential problems.

An additional advantage of the PMU system is the ability to define logic for controlling outputs. This is done with data from analog input channels or CAN bus data, and math operations can be defined for each channel. The PMU is also equipped with LED indicators to show the status of each output.

With the use of CAN keypads or steering wheel switches, all wiring is vastly simplified and lightened. Two other features are the inbuilt accelerometer and gyro for logging and “inertia switch” in case of an accident.
