How to Set Trailer Brake Gain | BetterWeigh™ Mobile Towing Scale


This video describes how to use the Trailer Brake Gain feature of the CURT BetterWeigh™ mobile towing scale. With this feature, you can easily set up your brake controller without the need for traditional methods of taking multiple passes and guessing at the optimal gain setting.

The CURT BetterWeigh™ #51701 is a Bluetooth-enabled OBD2 device that wirelessly syncs with your smartphone to provide a variety of vehicle and trailer weights. This includes vehicle weight, GCW, payload, tongue weight and pin weight, as well as weight distribution setup and trailer brake gain.

To begin setting up your trailer brake controller with the CURT BetterWeigh™, find a flat, open area to park your vehicle. Select the Trailer Brake Gain option from the home screen. Then, follow the screen prompts and enter your trailer weight and combined weight. Select your trailer type.

Next, calibrate your towing setup. Set the brake controller gain to 3. With the vehicle in gear and at a complete stop, fully activate the manual override on the brake controller. Then, accelerate in a straight line to 15 mph. When the progress bar fills up all the way, BetterWeigh™ will provide the optimal gain number. If wheel lockup occurs, tap the Lock-Up Occurred button and start again, adjusting the gain to the BetterWeigh™ recommendation.

If you increase the load on your trailer, enter the new trailer weight and BetterWeigh™ will automatically provide a new trailer gain number.

BetterWeigh™ is compatible with Apple and Android phones. Download the BetterWeigh™ app from Google Play or the App Store.
