The ECUMaster 8 Channel EGT Module adds per-cylinder EGT monitoring capability to the ECUMaster EMU standalone. Every engine has some variance from cylinder to cylinder, and the ECUMaster EGT Module gives tuners the ability to monitor and apply closed loop corrections to each cylinder in real time. The ECUMaster EGT Module is a separate device that communicates with the EMU over CAN Bus (requires CAN Bus module for the EMU) and can transmit information for up to 8 cylinders. The ECUMaster EGT Module is perfect for high-horsepower applications where maximum power output is desired.
