MotoGP » 50-year-old McWilliams talks grand prix return!


Greavesit:
TrueFan: I still remember him getting pole at Philip Island on the 400 Aprilia. He was the oldest man on the grid then too! Go Jeremy. You are a legend and a nutcase (in the best sense of the term). I hope it goes well, especially since they've dared to build a different chassis concept.
400?
Yes, they couldn't get the engine characteristics they wanted with 500cc. Apparently the pistons and the crank would have been too heavy, or something like that. Honda built a 500cc twin though.

MotoGP » Ducati software heading to Open ECU?


According to Motomatters, the new, big step, software upgrade file still had "Ducati Motor Holding" written on the code header, MM having failed to delete it from the file they received. So it looks like Ducati is going to continue developing their own software and, at the same time, will get rid of the five engines/20l of fuel nonsense, and all the teams will benefit from the new, free-of-charge, software. Of course, the guys who developed the software will be way more familiar with it than everyone else, and will have an advantage until the competition manages to wrap their heads around it. If that is not reducing costs for the average team, I don't know what is.

MotoGP » Valentino Rossi impressed by Open, Espargaro


Why people still put Dorna and fuel limits on the same sentence is beyond me. It was Honda who pushed for the 20l limit, not Dorna. And, by the way, all bikes on the grid this year are running the same ECU. the difference is in the software. Open bikes run the spec software, provided by Magnetti Marelli, and the factories are free to write their own. The spec software, for example, does not have one different traction control setting for every part of the track. The riders have to choose the best compromise for every track, somewhat like the street riders have to do with their much more crude systems.

MotoGP » Ducati: 'No further plans' for Open MotoGP class


JackSMU Magnetti Marelli have eight different models of ECU. Some of them require an external data logger, some don't. The physical ECU does have an impact on what parameters you can use. With the spec ECU you're stuck with the features that have been implemented into it and it is not possible to alter the software itself. That's why I say parameters and not algorithms. Good luck trying to make an SRD-160 ECU do the same a Marvel4.5 does.

MotoGP » Ducati: 'No further plans' for Open MotoGP class


Fullofit: Wow ... find myself agreeing with guys I never agree with! :D Just a question. Who has been manufacturing Ducati's ECU's up to this point? Isn't it also the Marelli gang? I wonder if Ducati would say to them "Here, use this software and these mappings in your Open spec ECU you deliver to all of them (us) ... nudge nudge, wink wink". That way they could race with everything they have now anyway, plus extra fuel & more engines ... and maybe a softer tyre.
If the spec ECU has the same programming possibilities as the Magnetti Marelli Marvel4, which most MotoGP teams used in 2013, Ducati can simply load all their parameters into it and lose nothing in performance. If it has fewer channels, which means fewer sensors, then they will have to come up with something new to work with those fewer sensors. I have a so-called racing ECU that has 12 different channels and is space age for club racing. A MotoGP bike has something between 40 and 50 sensors.

MotoGP » Moto3: Ana Carrasco secures seat, Calvo confirms Vinales


The standard bike has a slower engine, fiberglass fairings, which are heavier, and cheaper, heavier components throughout. RSMick, that's exactly what I meant, regarding the engines. The teams still have to buy them, but the factory can't tell who gets which engine so, not to risk having the factory supported guys getting a slower engine, all engines have to be the same spec.

MotoGP » Moto3: Ana Carrasco secures seat, Calvo confirms Vinales


JedPB67: Hopefully the KTM engine in the RW Kalex will be stronger than the Calvo KTM she had in 2013, she was basically riding a Red Bull Rookies bike.
The engines will be delivered to race direction on race Thursday, which will in turn pass them on, randomly, to the teams. No more special engines to anybody, which KTM denied happened this year.
