App for measuring lean, speed, acceleration using your phone.

Makes me almost want to get a smartphone.

From the story:

"Designed with the help of the Moto2 racing brain-trust, the Race Sense app takes all the metrics an on-board smartphone can read, then delivers full data readouts for later evaluation. The software uses the phone’s accelerometers, GPS, and inclinometer to plot information for braking force, lean angles, speed, and on-track location onto Google Maps — something that was only available through systems costing thousands of dollars — and allowing racers and team members to pore over reams of data to shave precious few milliseconds off each lap time."

When it comes out, I'm using it for my commute.

**** ya!

the pirelli app tried this, but it fell short. Just didnt work well and was a paint to use.

cant wait to try this!

It crossed my mind that GPS might not be reliable for helping real racers, since it will take the time between two points and average the speed between them. When there is a "jitter" of 4-5 meters, it can cause a miscalculation of speed by a lot. The accelerometer and inclinometer data will be useful.

For good GPS data, they would need some kind of differential source or WAAS or something like that to get sub-1m readings. A bluetooth adapter that broadast ECU data and then used the phone to process it would be more accurate, but then you are into big dolla's for the reader.

I'd be interested in how I took a given corner or ramp each day, or how I did on certain stretches in the city. There is no point to driving in the city unless you can win. This could enable creating a league table for commuting, kind of like rally cross where precision (not speed) is the objective.

Interesting... tell me more

If you've got the data, it's not hard to create a site to rank it.

Some rule about not doing 40 or 50 over in the city or something would be useful. There is the small matter of the data incriminating people, but that's a technical issue that could be solved in a bunch of ways.

The accelerometer and other sensor data could be used to prove the "smooth is fast" rule as well. It could be a sport of discipline and focus instead of just power and speed.
