ECRI Wireless Vehicle Calibration Device

ECRI Wireless Vehicle Calibration Device

I bought the ECRI to go from factory to 35” tires. The product looks clean and everything in one package. It did calibrate the speedometer but was not easy to get exactly right.
The install is easy but the OBD2 adapter is angled. It was not intuitive for me to plug into the OBD2 connector.
The IOS software loaded fine and seemed to work ok but I had issues a couple of times. Once I got the calibration exact I was done and didn’t want to continue with future use.
I never got the GPS calibration mode to work exactly. It was always one MPH slow.
I tried many times to just go back to factory settings but every time I scrolled to the bottom to the initial settings the screen on the app would refresh.
Once I thought I had finally got the GPS calibration to work correctly so I turned the jeep off and removed the adapters. I drove the jeep at 60 and it was spot on. 10-15 minutes later I decided to take the Jeep out and appreciate my work only to find that the speedometer and GPS had a 2 mph difference. I found that unplugging the 12v usb power adapter with everything else off and using the measure to the center of the wheel 2 worked. Finally 60 on the speedometer was 60 on the gps. Bonus the cruise also was set at 60.
There are a couple of features that it doesn’t have that it should. It does not have an auto start/stop delete. (I contacted the manufacturer who said it may be an option later this year.) There were YouTube videos that showed a setting that would remove the factory 1-3 MPH flexibility to allow for tire wear. This may have helped me in the calibration of the speedometer.
In fairness I didn’t contact the manufacturer to help troubleshoot which is the stubbornness in me to figure it out.

Works exactly as advertised, very user friendly and easy to use.

Works very well, super easy to use and it’s not limited to only one vehicle.

Put 35 inch tires in place of the factory 33s. Speedo was off 4 mph at 60. SGW was very hard to access. Once the bypass was installed the recalibration was done. First attempt using the measurement from the floor to center of hub made the speedo 2 mph to high. Did a calculation and plugged in new number and it is correct. Made a big difference in the way the Jeep shifts and performs. I think there should be a mention that when doing the last steps of the calibration that the Key fob needs to be away from the vehicle to allow all systems to power down. Did find that in the frequent question section. Overall very satisfied.
