Watching the press conference after qualifying; this is what annoys me most about Stoner. He talks about how great the bike was in FP3, and how relatively bad it was in Qualifying and yet he still finishes on pole, implying I guess that only his supreme awesomeness can account for his being on pole. Whatever, Casey, whatever. Fake modesty is worse than braggadocio.
i think his days at ducati proved he could still be fast on a bike that any other rider would consider a ****box
it must be supreme awesomeness:naughty:

After reading somewhere about how exciting the 2006 MotoGP race at Estoril was, I went back and watched it last night. It was one of the best MotoGP races I ever saw. That was the race where Dani Pedrosa wrecked himself and Nicky Hayden, and Tony Elias won it in a stunning effort. Today's race was pretty ho-hum in comparison. Oh , and Stoner crashed and took out Colin Edwards, breaking Edwards collar bone.

I really wish they'd get rid of this single tire rule. It seems to have created more problems than it's solved. It seems so hard to develop a bike to work well with this tire.
How much do you think it would cost to make tires and how much does it cost to develop an entire bike around tires during the season? Wasn't Michelin making tires in a truck special for Rossi and other riders back in the day. I think its time that the single tire rule went away and allowed these guys to get back to work and making their bikes the best they can be and the tires being made to fit the bike not entire grid. Makes no sense......

my memory of GP prior to the 1 tyre rule was a few riders getting the tyres that work and the rest of the grid having no chance to run up front.
IMO theres only one maufacturer complaining about it at the moment because they insist on using a motor where they cant get there weight distribution right ,not really a tyre issue

Careful Twista, the truth can hurt here. Rick's comment back at #678 is quite true, Stoner puts things in a naturally annoying way. It is still the case that the Honda is behaving like a pig with the new Bridgestones.

Stoner's excuse for letting Lorenzo catch him mid-race Estoril was that the rear was also chattering and he was loosing exit drive, slo-mo's on the parabolica coming onto the main straight showed it pretty convincingly too. According to Stoner, he found a new way to ride the Honda towards the end of the race, wicked it up an p!ssed off again. Seems to be his M.O., bugger off for the first half dozen laps, back off the pace and let the field (Lorenzo and Pedrosa) think they are getting a look in, then let loose in the last 3 or 4 laps to make it look like you were toying with them.

In Stoner's defence regarding comments on FP3, pole and race results: How do you say "What I did was sheer awesomeness" without saying "What I did was sheer awesomeness"? He gives off an air like he is beyond caring - understandably.


Lucky for the rest of the field Stoner hates the bike.
What makes you say this Vic? There are a few rumours flying about (that sound believable to me) saying that Rossi would like one. I'd love to be a fly on the wall if Honda grant Rossi a meeting.

Nicky Hayden (Ducati Team) 11th

"Starting from the first lap, there was an electrical problem and the bike didn’t know where it was on the track. I tried my best to ride around the problem and not make mistakes. We’ll focus on tomorrow’s test now and look forward to the next race at Le Mans."
Don't the riders know where they are on track? Aren't they supposed to be the ones telling the bike what to do?

On the bright side, we might be approaching a time when any monkey can hop in the saddle and win a race. Sort of like the space program in reverse. Going to see if my leathers still fit, and start the hunt for sponsors...

I thought they were only allowed one way telemetry from bike to pit.

That very well may be true, but that doesn't necessarily stop them from loading very specific data while the bikes are in the pits during the practice sessions.

Just more reason to bin the "electronics packages" altogether. But, just like getting rid of all the crazy aero-sht in F1, those guys tend not to listen to me.

EDIT: I haven't watched Moto3 yet, but Moto2 was much more exciting, am I'm sure 3 will be as good as 2 if not better. GP is becoming (already has?) become the same boring multimillion dollar parade that is F1. Not that I won't stop watching - not yet anyway.

Yeah another snoozefest. It seems like Lorenzo can hang with Stoner a bit better this year, so maybe they'll find something as the season goes on and finally dice it up, but until that day comes, MotoGP hasn't delivered much excitement in years.

Also kinda hoping Spies drops down to SBK next year, his one season there was mega-enjoyable.

I notice this comment in motogp homepage..sorry for my ingenuity...


"Nicky Hayden, on the other hand, just tried to make it to the finish due to an electrical problem with his bike’s ECU, which was subject to interference from a radio signal near the track. As a result, all of the electronic calibrations were out of phase around the circuit, making riding extremely challenging. The American nonetheless rode with great determination to an eleventh-place finish."



Hum... so it appears to me that the ECU is connect to a gps or tachmeter and gives the ""electronic Calibrations" to each part of the circuit !!!! interesting

poor Nicky he was in the end of the main straight and the ecu was in the parabolic..eheheh



anybody has a more detailed photos of the buttons in each handlebar




or some photos of the instruments





some more info about this ecu's/electronic aids would be apreciated.

If track data was pre-loaded and the ECU didn't have 2 way coms then it would not be subject to outside interferance.
It would have to be some sort of GPS tracking to allow for varying lap times.
And yes I think Stoner would complain his train set didn't follow the tracks properly.

That's a good point. However, anything electronic can be subject to outside interference if it's not shielded properly. A GPS system is a very likely candidate, and might be legal, since the unit is receiving only location data and not any voodoo from the pits. There is obviously some location information being transmitted, because it is used by timing and scoring, and is available on the website during the events. It would have been interesting to see where it showed Nicky's bike on track and how well that correlated with where it actually was.

If they use a centralized organizer sanctioned transponder system, depending on how it is configured, there is a possibility every bike would have been affected, not just Nicky's. This would happen if they were using some variation of a mesh radio system, where every bike is using the same frequencies and assigned distinct station identifiers (such as IP addresses). The organizer would have rights to view all data flowing over the system, and could assign the individual teams rights and permissions to see only the data the organizer/rules allows them to see. In my opinion, this would be the best system, since it would eliminate the possibility of the teams having the ability to actively communicate to the bikes.

Since his was apparently the only bike affected, I'm lead to believe the system is decentralized, or at the very least, the teams are assigned different frequencies to send information to timing and scoring. But, if that were the case, wouldn't the organizer (network control) ensure those frequencies were cleared within the confines of the track to eliminate the possibility for interference? A simple survey of the area with the proper equipment would give a profile of the radio environment, and allow them to configure their communications plan accordingly.

I hate to say it, but based on my less than comprehensive knowledge of the rules and exactly how their systems work, I might be easily convinced that there are shenanigans afoot.

interesting, ecu from Cosworth
Case Studies


MotoGP & WSBK


2011 was an important year for Cosworth Electronics on the sports bike side, as the MotoGP and WSBK regulations allows ride-by-wire system. A new control software has been developed in close collaboration with the WSBK Castrol Honda team. Not less than 5 riders were involve in the development.
Cosworth WSBK system raced for the first time in IMOLA and won the race against all the official teams.
Pectel MQ12 Engine Controller
Pectel most advanced ECU feature a newly developed sector-by-sector mapping, allowing calibration changes depending of the position of the bike. The MQ12 also feature active Engine Braking Control, anti-wheelie, launch control and Traction Control. This ECU can also send split time to the Omega Dash.
Pectel DB1 Card logger
The DB1 is a compact flash card writer used to log the information send over CAN by the ECU. The logging memory is up to 2GB and the bandwidth is up to 8000 samples/second. This provides a very flexible logging system where you do not need to plug a wire to download the data. After each outing, the data engineer replaces the card by an empty one and can use the data logged while debriefing with the rider.
Omega Dash
The Omega D1 Dash is a highly configurable dash, where the writing is clear and precise. The removable shift light module allows it to be mounted in the optimum position. The dash can display alarm from the ECU, lap time, Gear, Traction Control setting, …
IMU
The IMU (Inertial Measurement Unit) is able to measure all three axis of acceleration (AccX, AccY, AccZ) and angles (pitch, roll and yaw gyros) of the bike for data analysis. The lean angle is use to correct the tyre diameter as the circumference isn't the same depending of the lean angle. Our IMU is communicating to the ECU via CAN which ensure a reliable signal to be use for control strategies.
GPS antenna
The GPS antenna is wired directly to the ECU. This information can be used to trigger lap beacon or control strategies. We also use the position of the bike on the track to compare rider's lines…
Wiring Harness
Often overlooked but an absolutely essential part of any race car. Wiring issues are both complicated to diagnose and difficult to repair so Cosworth ensured they were built to last with excellent reliability.
