I had the exact same model from amazon and it kept shutting down. Returned it and got it from auto anything and it works great.

Software did not seem to load properly...after contacting SCT, found that the instructions to update the firmware were wrong. Loaded fine after a long online update. JK runs fine on 87 octane program, a noticeable improvement in midrange power...some on the top end. Too early to tell if any fuel mileage improvement.
