Magnetti Marelli
Subsidiary of Fiat Group who happen to be Yamaha's current major sponsor.

Oddly, ferrari, at least until recently a subsidiary of fiat are also rumoured to have helped ducati.


Yes of course, nothing wrong with all that... But Marelli manufacture and sell the base system i.e. the ECU with sensors, actuators, operating system and programming language - the 'racing' software is written by the teams starting from that base, as it can only be coded for the particular bike and Marelli can not do that. So Yamaha and Ducati may share the same ECU base, but the software that makes the ECU really useful is developed independently and that inevitably results in completely customized and different systems.

I don't know enough about this so it's just really honest questions from my side:
Is it really they way you say?
What about programming errors?
Just having an OS and true, even very high level, programing language, wouldn't that put the rider in an imense risk every time the program is recompiled?
What happens with a divide by zero?
How about typing errors making things go the oposite way?

Wouldn't a precompiled set of advanced regulators with a wide varety of parameters be the way to go? That way hardly any logic could fail, parameters could have absolute min and max limits, so on.

Doing a similar, allthough more advanced, fly by wire took SAAB quite a few years and a few billions in crashed fighter planes to complete. That we sould have programmers altering the actual code inside the bikes after every session would scare the .... out of me.

Not as scary as say running the setup for say PI at maybe say Brno

Ferrari were said to have helped them with the actual set-up of the tc, with which they of course have some experience.

so thats why Michael Schumacher never fell off

Yes, he was obviously used to the traction control settings .

Seriously though, whilst I am a bigger fan of motogp now, I have been an F1 fan for several decades, and I am a huge schumacher fan. When rossi did a competitive time driving a ferrari, people said this was only to be expected. Why is it surprising that arguably the greatest F1 driver ever can go reasonably fast on a motogp bike, not that 5 seconds off the pace is all that fast? You can bet your bottom dollar given his competitive instincts that he had some tutelage prior to his latest run given his slower times in his previous attempt.
