Does exactly what it is supposed to do. Take it out of the box, plug it into your computer, and get the updates. Take it out to the Jeep, plug it in. Select a function. Follow the on-screen instructions. It walks you through, step by step, exactly what you need to do, and tells you when it is done. Nothing is idiot proof, but this is very well designed to be strongly idiot resistant. You just need to know your actual tire diameter and you're fine. Compared the speedo against a gear chart and speed vs RPM is right. Haven't asked someone with a radar gun to clock me, but I'll get to it. Or they'll get to me, one or the other. I really can't think of anything bad about this programmer. I bought it to set my tire size and pressure. Later I'll use it to set my gear ratio when I go to 4.56's and lockers, and idle up for winching as needed. Its pretty cheap as far as programmers go, user friendly, does the trick and no funny business. Also comes with flashy stick-on Superchips badges for your Jeep. Cool.
Overall this was a simple plug and play item.
Worked well recalibrating the tire size on my JKU. I also changed the daylight lights to the fog lights.
Worked perfectly, got me through emissions inspection. Super easy to use. I like it better then the other brand I had.
Best option for corrections in my opinion. Love the upgraded software allowing auto start stop feature to be disabled.
It worked just like advertised, very easy to update and use.
It's hard to talk to someone on the phone or get help but be patient these guys are very busy
Exactly what it says it is....easy to use and very convenient.
Great product, if you they have issues with updating the software, flashcal customer service is great
Perfect and easy to use. Fixed my speedometer in a flash
You can change several settings. I turn off tps when off roading turn back on for street drive. Kinda nice
