Can the Cold ECT Defuel Be Turned Off on Edge Juice with Attitude CTS2 for 2005 Silverado Duramax

Updated 03/03/2016 | Published 03/02/2016

Question:

How can I turn off the cold engine protection back down feature on the cts2 for my durmax? I live in montana and its cold here all the time my engine NEVER gets hotter than 160 when just driving around town during the winter or on the highway for that matter. Does this mean I cant use my edge product at all in the winter? If so how do I return an already installed product?

Since the Cold ETC Defuel function is a safety feature on your Edge CTS2, like the Juice with Attitude CTS2 # EP21501, it cannot be turned off for your 2005 Chevrolet Silverado Duramax.

My contact at Edge says the heads on the Duramax engines are made from aluminum, so not having the Cold ECT Defuel on can cause damage to the engine. This is why the temperature setting is as high as it is for the Duramax.

Though the feature cannot be turned off, you can certainly still use your Edge programmer in the winter. You will want to use a grille cover or something similar to block off about half of the radiator. I confirmed with my contact at Edge that this will work well for you to use your CTS2 through the winter with your Duramax.
