telemetry v. data

[Spidey]

I've never dealt with set-up on a bike much more than just front and rear suspension, raising/lowering the front/rear, changing tire pressure, altering axle position with chain length, and playing around with ergos.  Never had to deal with data at all. 

So what's the difference between sharing telemetry and sharing data?  Is 'data' just suspension/ergos set-up while telemetry is the whole electronics/traction/engine management system?

Not sure if there's a true distinction, but telemetry simply means a set of data coming in over time (e.g. suspension travel through this corner, throttle position through this section of track etc), whereas data seems all-encompassing: Here's the telemetry data...in addition, here's our suspension settings, our ECU mapping, etc.

^^correct.

...as i understand it.

Kinda splitting hairs, but here's my understanding.

Telemetry would be data that is transmitted from the bike to the pits 'on the fly' via a 'radio' link.
Not sure if the bikes can use this, F1 cars do.
I'm pretty sure the cars do a 'burst' transmission of all the data as the car goes past the pits.

The data would be from the various sensors on the bike; suspension position, throttle, brake pressure, engine rpm, gear, tire temperature (AFAIK outlawed for MotoGP '10), front and rear wheel speed, steering angle, oil temp and pressure, airbox pressure, fuel pressure, or whatever the hell else they're interested in.

Data would encompass all of the above, plus suspension settings, slipper clutch settings, ECU maps, wheelbase, rake, trail, ride heights, suspension linkage info, and whatever else is adjustable on the bike.

...and whatever else is adjustable on the bike.

Including any weight that suddenly shifts rearward into the rider's underwear during a near-highside

Didn't anyone make you study etymology?

Tele = Remote
Metry = Measurement.

Telemetry refers to real-time data acquisition from the (remote) vehicle, used to offer feedback to the driver/rider. Not used a whole lot in MotoGP (at least to the extent it is in auto racing, where the pit actually talks to the driver during a race)

As for sharing the data... that's a tough one. There's sharing your data and then there's sharing your conclusions and settings that you've gathered from looking at the data.

I'm guessing the teams share the former a lot more than they share the latter. The factory is going to be interested in how the components are performing, so that data seems to get passed around a fair amount.

However, the racing teams are going to be more interested in the magic settings to get the components performing the way they want them to. This, by and large, isn't shared much (except apparently at Ducati, which according to stories supports its satellite teams quite a bit)
