ECRI Wireless Vehicle Calibration Device

Speedometer Recalibration

The ECRI unit did exactly as advertised for my speedometer needs. The directions and video were helpful and easy to follow as I recalibrated by Jeep Gladiator for new 37” tires. I also took advantage of a couple of other featured setting controls that weren’t important to me when ordering the unit (such allowing my fog lights to stay on with high beams), but have been an added bonus since making the adjustment.

Did what I needed it to do

Great Product and easy to use App!
