Works great on my 21 Escalade
Bought this for my 21 Escalade. Start stop function is now gone and the car seems to run a lot better. No noticeable change in gas mileage after a 300 mile trip with both city and hwy driveing. A must have !

did not work - numerous trouble codes
Installed per instructions. Three trouble codes came up regarding engine and transmission. Also the fuel gage stopped working. Called support and followed their troubleshooting instructions. Nothing changed. after removing it things seem back to normal normal and i am thankful nothing appears to be damaged. Truck is brand new so the stress level is high. Range technology wants me to pay return shipping so they can repair it. At this point i am skeptical of the product and support.
