The thing is, the spec ECU still doesn't really seem to address anything to improve the competition or the racing?
My point is... all these complicated algorithms so the bike knows exactly where it is on track, and can then take decisions on mapping and adjustments to optimise the bike for every part of a given track... its of zero use for 'development' of technology to filter down to road bike development right? Unless you only ever plan to ride the same route exactly from your house without variation that is!
So.. if it is expensive tech that's only purpose is to maximise a bikes setup for a race at one circuit, and that by doing so it costs a fortune and actually makes the racing rubbish - then why the hell keep it, except to pander to the factory's and let them keep their tech and budget advantages so that its next to impossible for them to be beaten eh?
It seems that this is a fine example of how the factory's run MotoGP really, and that Dorna....

Wasn't there that thing where Lorenzo's bike thought he was on a different part of the track and used the wrong engine map? Or is GPS something else?

I remeber that MC. yes, he dived into pit lane in Quali to get rid of a guy getting a tow I think.

The ECU map had been employed to maximise the bike for a flying quali lap - by going down Pit lane, he 'confused' the system, so that the bikes set-up was then being altered to suit a different part of the track to the bit he was actually on. This of course resulted in being unable to maximise everything and get the fastest possible lap.

This one incidednt proves just how sophisticated the sustems are, and how dependent the bikes are upon it to gain every advantage.

It also means that as the bike is maximised for every single bit of track, that there is virtually no areas for a competitor to exploit to try and execute a pass - even if they can run fast enough to catch the guy in front (remember Cal being able to close with Dovi several times, then being stuck behind even though he was faster?)

It was haydons GPS that went wrong so was mapping his anti wheeli, mapping and tc on the wrong corners. Think this is ridiculas should be there wrists that do all this, read an interview with B Smith and it took his tech 3 team 4 hrs of datalogging each track at every track every time. It's up to the rider to do this, not a computer.

It was Haydens and if he had GPS it would not have happened.

SPec ECU means someone will decide what I/O will be allowed so first thing out for Honda is Asimo's gyroscope. With limited I/O there will be limited parameters, I am sure the factory will try and multiplex but that may be policed. The battle will basically become a battle between each factory and Magnetti, but more will be feeding back to Magnetti.
There will be many benefits from the challenges the software guys face, its not just about where the bike is as what its doing in any situation. The big challenge is fuel as the world wants economy.
Anybody who complains about electronics should get used to it they are here to stay, if you don't like it throw your PC/tablet,TV,cooker,washing machine etc out the window, sell your car and bike.

I'm not a complete Luddite Mick, but there's gotta be sensible application surely? And lets face it, there have to be FAR better ways to develop useful and practical fuel economy strategies than by hammering a bike at full chat round a racetrack?

This is RACING ffs! The Mfr's can (& no doubt DO) play the fuel economy game somewhere else.

For one thing, as i understand it pumping losses from pistons is a big part of efficiency - so a a high-revving engine is a thirsty engine (and why the Honda NC700 has such a (relatively) low-revving lump in it.

According to your argument Mick, then MotoGP bikes should have a 7K rpm ceiling so they are better on juice!

I'm still looking for an acceptable counter as to why getting simple and fixed engine maps wouldn't actually save a load of cash AND actually make the important bit (yup, that'll be the Racing) far better in a single stroke.

RS Mick. To be honest, I don't really have any hope of knowing exactly how the factory teams you mention are funded, but of course I accept that there's commercial interests and agendas in WHY funding is provided.

HRC has Repsol (Oil) Yamaha has well, Yamaha and Ducati has Phillip Morris (Cigarettes) as their Title Sponsors AFAIK. But I accept that there's likely to be many more contributors.

Still doesn't answer why someone would pay to develop algorithms for fuel strategies suitable for a racing engine round a racing circuit - both items that are entirely alien to any real-world scenario where fuel economy development might be of any practical use. But a Sponsor does want air-time and to be associated with a Winner though, right?
