I believe they use changes in the TV angles, hitched and not hitched, to determine the tongue weight.

and read answers to the questions.
Interesting, I just looked at the pic. Now that Iíve read your post I admit it does look like an OBD2 adapter. Wonder how accurate it is.

First belly laugh I had today, very nice one. :-)

If you watched the videos, you would see it plugs into the OBD2 port.

Technocracy is truly amazing. "What'll they think of next?", is what comes to mind, after "Huh?" and "Whaaaaatttttt???"


How 'bout somebody get it, write down what it shows for your weights, and then go through the CAT scale and report to the rest of us how the numbers compare? Hard to believe nobody's done that yet, so I expect someone has. I'd volunteer, but it sounds like a lot of trouble.

Update - just checked at their website and looked at the video showing use of the device and app with an F350 to estimate the weight and then going through the CAT Scale and the weight difference was only 38 lbs. He also stated that they generally see + or - 5% in their tests.

So, somebody please still go do the above comparison and report back in to the rest of us, but sounds like the company has done comparisons with actual CAT scale weights.

I've emailed them with some questions.

Since I already own a Sherwood TW scale and have made multiple trips over the CAT scales I do not "need" this product.....but it does intrigue me.

I've asked if in my particular case with such an imbalance of TV capability versus our actual trailer weight and minimal TW if that it could possibly impact accuracy. If they're confident enough in their accuracy then I may just take them up on the challenge

I've ordered one and it should arrive today. I have weights from a scale at the county inert materials dump (5430lbs) for my 2016 F-150. Right now I'll be using that weight to see how close this comes. A trip to a CAT scale will be at some point down the line.

I'll post in the next few days what I find.

Here's the patent: https://patents.google.com/patent/US9290185B2/en

I don't know whether they have some extra electronics in the module or whether they've managed to get it all from OBD PIDs. There is a ton of data streaming from the OBD port but unless one has doc's that give them what's what I don't see how they'd find what they need. I made up a CAN bus sniffer and in about 5minutes logged a few megabytes of data off my Chev. The only code I isolated while I was playing with it was the door lock/unlock

Here's a good explanation from the man that developed it.

From a pure engineering standpoint it seems solid....but in real World application I'm not 100% convinced yet.

I really want this to work, I think it would be a nice tool to have.

So far I use Levelmate Pro for leveling and Tank check for propane, so I embrace technology.
