I have an Edge CTS that I purchased 2 years ago brand new. It is is my truck listed in my signature. It has recently stopped reacting correctly to touch. For example I want to change my EFI tune and it brings up the fuel pressure gauge to change. I called Edge and was told that they no longer support the CTS because they can no longer get parts. They did offer me a discount on a CTS2. Why would I want to purchase another one to potentially have another issue in 2 years that they can not support? So my question is this, are there other monitors that will change my EFI tunes? If so what brands?
