Works good used it to correct speed odometer. Used the gps function speed odometer is dead one. It’s super easy to use I do wish it would have the ability to turn off the auto start and stop. I would rate it 5 stars if it had that function
Purchased the ECRI device for my 2014 jk after swapping tires to 35’s. It was easy to use and immediately made improvements in my shift points, the lag I was experiencing is gone. Annoying TPS is not staring me in the face either.
Veey easy to use and great product
Have always been hesitant to use something like this thinking I would mess up my vehicle not knowing what I was doing, but after seeing a friend use his I knew it was as simple as it sounds. I had my wife’s jeep calibrated to her larger tires in less than 5 min. Lots of extra features too. Awesome product.
I changed the tires on my 2017 Wrangler and I saw the was consuming more gasoline and a little bit slower on the response when I step the gas pedal, but since I got my ECRI it’s being a lot better on gas used and also the acceleration is better, so definitely it worth what I paid for it!
