Works great lots of options. Very easy to connect and update to change settings. Very Happy with purchase.
Did exactly what I wanted it to do!
I recently upgraded my 2018 Jeep Wrangler JL Sahara from the OEM to 33-inch Mickey Thompson tires and new 17" Quadratec rims. Without the recalibration my Jeep was very sluggish and gas mileage way off. The ECRI device completely updated everything, returning the gear shifts to where they needed to be and making everything much smoother. Gas mileage back where it should be. Completely worth the initial cost, and you can share it with others, minus a one-time $50 fee. Great business model and USA product. Thanks!
Totally worked like a charm !! Speed is now perfect !! This product is amazing ! Gonna pass this product on to my Jeep club members !!
Plug in 5 minutes later your done
