Curt BetterWeigh?
Curious if anyone has tried this? Looks like it would be interesting, if it is accurate. Mixed reviews on Amazon. Clicky

This type of technology was used 15 years ago in sports. Amazing amount of data can be reversed into real numbers. 5% accuracy seems right inline with the tech.
With similar tech it is possible even to generate an aerodynamic resistance curve at any given speed, so you can figure out which speed yields highest mpg's. You can change your aero wing and see which location is best. You can see how much Hp is needed to start and stop. You can collect the data for every data point, graph it, and analyze it after a drive. You can compare winds and crosswinds.
I dont think this particular unit does all of this, but I have played with the technology years ago with success.
The way I calibrated it years ago was to accelerate up to 25 mpg then coast down. I guess using neutral would be needed, not just coasting in D. The device figures out aerodynamic coefficient, ground/tire friction and other numbers from this. You then could, theoretically, do a coast-down again with the trailer and compare. You will need to use the settings for trailer when trailering, and settings for no trailer when you dont have the trailer...
Based on aerodynamic coefficient and slope of the hill you are on (device knows the angle) it can generate how much power you must be putting out to go any given speed.
Knowing the weight is new to me. I always had to put in the exact weight for the device to work, but I think this vehicle device is going off of the factory given weights, which will always be wrong due to cargo in the vehicle, weight of the person, amount of fuel in the tank etc...
Looking forward to hear feedback from those that actually use it rather than opinions of those who have not..
