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

At first an update was needed but easy to navigate the programmer.

Much needed item after installing larger tires.

Great, reprogram my jeep after installing 33" tires.

Awesome, product! Does as advertised, speedo is now correct and shifting is at proper adjustment

very easy to use. I adjusted my speedo for larger tires and was able to get right on with my GPS took a couple of times to get it right on. I suggest and inch or so smaller than your actual tire dia. as a good starting point

easy to use and program your jeep, made a big difference with my jeeps performance after programming for bigger tires and changing the gear ratio. highly recommend.

Great Product - Good Price

I can't say enough about this. I lifted my 2017 JKU with a Metalcloak Dual Rate 3.5" and put Nitto Ridge Grappler 35/12.5/17 tires on it. I watched my mpg go from 22mpg as a stock jeep to 15.5 with the new setup. I was ready to accept that that was just how it was going to be. Then I did some homework and even emailed the techs at Superchips. They said to at least buy it to correct my tire size. They were right after adjusting it to the correct size I am back up to 19 mpg. When I regear next summer this will come in handy once more.

Finally got my DRL's and a few other features packed in this tool

Used to reset tire size and turned on driving lights on our 2016 Rubicon.
