ECRI Calibration for Jeep Wrangler, Gladiator and Dodge Ram

It's "ECRI Easy" with dozens of calibrations at your fingertips.

Get Started

Tire Size - TPMS - Speedometer - Axle Gear Ratio - Factory Reset - Daytime Running Lights - LED Signals

Speedometer calibration today, turn TPMS light off next week, LED light install next month, gear install next year…accessorizing your Jeep never ends.  Be on top of all your current and future mods with ECRI. With the price of ECRI being less than one visit to the dealership, it’s easy to understand why ECRI is such a common tool for Jeep owners.  
 
Calibrating your speedometer is by far the most popular use for ECRI.  It’s so easy to fix your speedometer reading that we call it “ECRI Easy”. Accurate tire size calibration means accurate speedometer, improved fuel efficiency, better shifting, and less stress on your drivetrain.

Amazing Support

I bought this to reprogram the tire size and gear ratios of my Jeep. when I launched the app had a few errors when trying to push the configuration. I opened a support ticket and within a few hours I had a response and support pin pointed the issue to one of the modules on my Jeep having a misconfiguration. Support helped me get the configuration changed on their end and I was able to update my jeep.

It was refreshing to have support from a company actually respond and assist with finding a solution for my issue. They could easily just said there was an issue with my Jeep and not have gone the extra mile.

I will be buying licenses for the other Jeeps in our family.

Excellent Product!

Purchased to recalibrate the Speedometer in my 2012 Wrangler. Works great, easy to set up via the Instructions, and a great, inexpensive alternative to other products to recalibrate the Speedometer. Great features such as DRL Setup and TPMS Threshold are nice.

App was a bit glitchy when creating an account, but after inputing the Login info, if it goes to a blank screen, close the App and reopen, should work just fine.

Highly Recommend!

TPMS

I finally got rid of my annoying TPMS light and calibrated my speedometer while I was at it. Worked like a charm on my 2013 JKU.

TPMS KILLER!

$100 a crack at the tire shop each time a TPMS fails on my my '15 JK aftermarket wheels. Two minute shut off with the ECRI and now no more idiot light and system chime fault.
