EWP & FAN DIGITAL CONTROLLER

The updated V2 LCD Digital Controller how has two specific functions. This unique Controller will now manage the operation of the EWP by varying the speed of the EWP in response to the temperature of the engine and manage control of your electric engine fan. The Controller has a push-button on the facia panel that offers target temperatures Singular degrees from 40C (104F)to 110C (230F).

Generally, higher engine temperature will offer improved fuel efficiency and lower engine temperature more power. The LCD Digital Controller will now operate the engines electric fan automatically once the engine has reached +3c above the target temperature. A significant benefit too is the Controller allows the EWP to run on after ignition shutdown to reduce heat soak. It is recommended that engine operational temperatures be checked with manufacturer.

We have side mount alternator brackets also, please check our other listings for combo deals!
