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

Works like a champ. Adjusts many parameters that are kind of novel like day time running lamp. Updating the firmware in the unit is easy too. Would definitely recommend.

Works great. Easy to use with a quick scan of the instructions.

Great purchase, fixed a few issues after the lift and tire upgrade.

It does exactly what it advertises. I only needed it to change my speedometer with new 35" tires. Fast and easy to use

I just changed gear ratios and tire size on my 2013 JK Sahara. I used the Superchips Programmer. It was simple, quick (less than 10 minutes) and flawless. Transmission function and shift points seem fine! Could it really be this easy ?!?!?!

Love the Superchips 3571 Flashcal. Used to correct speedometer and shift points after putting 35’s on my JKU. Super easy to use. Highly recommended.

It doesn't get much easier than this to program your Jeep and to read diagnostic codes. Update the software using your Mac or PC before programming your Jeep. Turn the ignition on (don't crank it) and follow the simple menus on the programmer. Only took a few minutes to update my tire size, change my daytime running light options, and lower the TPMS warning threshold.

good customer service. works great.

Fast shipping works as described. Super easy use

So easy to use, you'd think Apple made it. (Tho it's kinda ugly, haha) Recommended!
