Jeep JT JL OBD programmer for under $100. 

I know the phone was blurry. Sorry about that but I made it so that its step by step.I found an extremely cheap way to adjust tire size and a ton more for my jt jl. This system was very easy to use and was extremely cheap for cost. I can share the pig tail and bluetooth odd with any of my friends and all they have to pay for is the vin number for the app which is 30 bucks in Canada.
The system does so much more that just do tire sizes but thats all I need it for for now. You are going to need the pig tail to install this on new jeeps as there is a security bypass that you need to get around. If you have any questions like I did the customer service was extremely easy to get ahold of and very helpful. Hope you like it.
