Does the Curt Echo C51180 Need to be Mounted Level to Work?

Question:

2014 ML 350 blue tech The ML 350 factory installed 7 way plug is at a 45 degree angle down relative to the ground. Will this angle limit the the Echos capability to sense fast deceleration and apply the proper signal to the electric brake pump? I often have to use manual button on the iPhone to get the proper proportion of braking on the trailer. Thanks

The Curt Echo # C51180 does not have to be mounted level for it to function properly. The 45 degree angle of your 7-way plug does not make a difference in the functionality because of the unit's triple-axis accelerometer. The accelerometer is able to sense the angle that the brake controller is plugged in at and still engages the trailer brakes effectively. I included a video of the Curt Echo being installed on a Toyota 4Runner that has a 7-way plug at an angle.

With that being said, you may try turning up the sensitivity of the controller to get it to "hit" harder when the brakes are applied. You should also check to make sure the brakes are adjusted properly.

A potential add-on would be the Manual Override Button for Curt Echo Brake Controller # C83HR. This can be mounted anywhere and is a lot easier than trying to grab a phone in an emergency situation.
