How to Get Payload Weight with HaulGauge [New Towing Product]

[@NissanPRO4X]

How does this work? Are you using sensors at the suspension or some built in eclinometer? I don't understand how this could even be remotely accurate.

Thanks for the question! The payload, tongue weight, and pin weight measurement features of HaulGauge use an accelerometer in the HaulGauge device (plugged into your OBD-II port) to determine the pitch of your vehicle. All we need to know to be able to determine payload and other loads in this way is how much your vehicle pitches under a given weight.
We've pre-calibrated this information for a number popular towing vehicles, but if we haven't gotten to your vehicle yet, the app will take you through a calibration process where you sit on the tailgate or rear bumper of your vehicle, enter your own weight, and the app calculates how much the accelerometer moves under that much weight, thus enabling it to determine how much weight you're carrying in the future just by checking how much the accelerometer has moved on the horizontal axis.
Hope that answered your question!
