        Good tuner?

        Bought this specifically to adjust my gear ratio for my tires, but because I don’t have a Rubicon, that feature doesn’t exist. As an engine tuner it works great.

        Not impressed

        I've been trying to get the tuner to load a tune into my 02 TJ for over 2 weeks only to have an error message saying there is no tune in the tuner. The computer says it's loaded and ready to go but no tune is found when plugged into the Jeep. Called Diablosport and had they got their engineers on it, told me it was fixed only to have same issues. Even with different tuner same software problem. I got so frustrated with it I sent it back.
