The EGT (Exhaust Gas Temperature) unit is an optional extra normally used on diesel engines to control the EGT to safe limits. With this option installed the power can be safely increased even more and if the EGT goes too high the Unichip will automatically trim back the power to get the EGT back into the safe range.
