Reviews for Superchips 3571 Flashcal F5 Programmer for 07-18 Jeep Wrangler JK

Was better then I expected and easy to download, I also went ahead and upgraded it which I am glad I did. Easy to use and read.

Worked as advertised, made the changes I wanted and is upgradable at a latter date.

Plain and simple!!! Does exactly what it is advertised to do!!!

I recently bought a 2007 Jeep Wrangler that had an incorrect speedometer reading- 10+ MPH too fast. The previous owner had programmed the computer for oversize tires. I tried another speedometer calibrator first (less expensive). It couldn't rewrite over a previous program but they were fine about letting me return it. Quadratec's Customer Service department let me know ahead of time they thought the Superchips Flashcal F5 would be able to fix my problem so I gave it a try- worked great! Fantastic customer service and great product.

I have used it once to check for codes and twice to adjust my speedo for tire upgrades. Works flawlessly!

Works great and easy to use.

Really easy to use. I am getting better gas mileage.

Super easy to use! After adjusting tire size the Jeep drives and shifts like it should!

Works great! recalibrated the PCM for my larger tires and it changed my shift points in the Transmission.
Love that I can use this to turn off the lane change setting and keep my fog lights on when the brights are on too!

I put on a leveling kit and 33.7 inch tires. My speed was way off and the jeep didn't shift when it should have. I knew I needed this but was a little nervous about using it. It took me ten minutes. And now my jeep runs like it should. The menus were super clear about what had to be done, when to turn on your ignition, etc. The Flashcal did EXACTLY what it was supposed to do and was so user friendly anyone could use it. Now that the tire size is changed, it will stay in the tool kit to diag codes. Buy this with confidence.
