You know, what happens when you drive through mountains.
The most reliable slope gauge I have is actually my scan gauge. The instant MPG reading will tell you if you're going up or down hill or flat. When it's reading 15 MPG I'm going up a 7 percent grade. When mine hit's 60 mpg, I can shift into neutral and coast. Anything steeper (more INSTANT MPG) than that going down hill and I will gain speed.
These speeds are only true at 60 mph, give or take.

Yeah, mis-reads from curves and movement around mountains and hills won't work around here in the Bay Area... just a mountain or two around here!
Actually, watching my MPG go up and down on my UG, while on cruise control is what gave me this idea, because the MPG change will tell me of a slope up or down, but not how much. I just wanted something a little more accurate.

Also, a gyroscope will be more accurate than the fluid filled inclometers in respects to false readings. And it wouldn't be hard for an app to differentiate between acceleration/deceleration body tilt and incline by using accelerometer data. I.e. braking would produce a different accelerometer reading than going down hill, yet both would cause the body to tilt forward.

So now the question is does the S3 have OTG? Also, having a UG already, I don't know how I can get Torque or similar to work, unless I get a splitter cable, but then I am eating up an awful lot of bandwith.
So a gyroscope will indeed work then? How would I go about setting it up? How do I know if my car has an accelerometer? Do I need that with a gyroscope or would that be a separate system?
Thanks!
