All bikes have now been converted over to the .pkz file system.

Still waiting on the FTP
Great job !!  Thx

You know MaxHUD has something very similar to what you're asking, right ?

[of course PiBoSo could do it ten times better and integrated in GPB/WRS/KRP/MXB]

Counter-leaning, FTW !! :)

Give me a truckload of pylons, same bike/setup and a week, I would beat their time. FUCK the POPO! 8)
Bet coming ...

Give the MotoGP bikes full throttle with AW and listen to the engine. The frequency of "throttle change" is much lower than the frequency at which the handlebar oscillates during tankslappers.

But regardless, that discussion belongs here. AW/TC being deactivated in both videos means that it's irrelevant to this discussion right here.
Hmm, I will have a look. As far as I can remember the two freqs were not so different.
It's a pity we can't see this in the telemetry (we can easily see the tankslapper freq but not the throttle cutting due to the AW, we only have the rider's throttle pos).

Hmmm did a (too) quick try. Manu's Honda motogp on victoria, TC at zero, AW at 3 (direct lean 100%), default setup.

1. I seem to have no tankslappers (but may need to try more / push more).
2. When AW kicks in, the ON-OFF freq is surely faster than the freq of a tankslapper so at least in principle, the AW could make things worse (mind, it's not a proof it does).

Any track/bike combo that makes tankslappers very obvious for you?

I don't understand what you mean by low-pass filter in this context exactly.
And what is the "cut frequency", as opposed to "sampling rate"?
It was just an example to show you a situation in which, past a certain sampling frequencies, there's no difference at all. It's very basic control theory stuff.

Underdamped oscillations happen even in simple linear systems when the controller is badly tuned, even if the sampling frequency is 10, 100 or 1000 times the one actually needed.

In GPB case, I wouldn't be surprised if the ECU is in fact designed as a bunch analog filters (plus some logic) integrated over time just like the bike dynamics at a very high sample rate (like 500Hz or 1000Hz, can't remember if PiBoSo ever disclosed this). If that's true, then there's no way to increase the sampling rate (unless one wants to increase the integration frequency even more).

Your reasoning (higher sampling freq = better AW) would be eventually valid if the AW was something as rough as "if pitch angle > 10deg then cut throttle to zero" and the sampling freq was very low (let's say below 10Hz). But hopefully in GPB there's something a bit better than this (but very likely not as good as a good modern AW). AW control is not that trivial on a real bike.

P.S.
If I recall correctly modders have very little AW parameters to play with (and I'm not even sure we have a clear description of what they does).
It's way more likely that the bad tuning (or plain bad AW algorithm) is responsible of poor AW performance.

A higher sampling rate would be mean more, small steps instead of few, big ones. So it should certainly smooth it out, regardless of how the algorithm works exactly.
Not necessarily, the "smoothing" may be totally irrelevant.
A low pass filter with a 10Hz cut frequency can be sampled at 100Hz, 1000Hz or 10000Hz and it wouldn't make any difference.
And if the low pass "is not the right filter", then even less.

Yes, big +1
For one it needs a much higher sampling rate.
At the moment you are much faster / closer to the limit without AW/TC because it just cuts way too much power too abruptly.
It probably needs a redesign more than higher sampling rate.
If the principle is not good, you can push it to 2000Hz and it would still be not good.

Not saying you're wrong and Manu right, but :

The frequency of those wobbles is far too high to be caused by the AW (which has a pretty low sampling rate).
How do you know that ? And low compared to what ?

Bug Reports / Re: Anti wheeling makes wobbles
« on: December 05, 2017, 02:15:05 PM »
what make me doubt about anti wheelie is that i ride in Direct Steer Hardcore mode (DSA) wich mean the virtual rider don't do anything, i even can steer my bike on wheelie, but i still got horrible wooble and it's just impossible to ride moto GP bike. Also, i don't think it has to do with bike's power because i can easily drive WSBK with is in the range of power (less of course) of moto gp bikes. Anyway, i'll try desabling the AW and give it a test.

i can ride moto gp bike but by disabling my FFB. and DSA without ffb is worst than a suicide !
If you use DSA it's a whole different story, especially if you have FFB.

Yes. It can be seen how the throttle opens and closes sharply during the wobbles.
Should be proof enough then. Not sure it will solve the issue completely, but for sure it doesn't help.

You're making me willing to fire up GPB again :)

Interesting.

Can't remember: is the effect of the AW visible in the debug stuff on screen ?
Do we see the throttle "reacting" to the wobble ?

@Peter: Sorry, could not make the test race yesterday due to work assignments. Will be participating next weekend.

I have a little daughter now so my time gaming is limited  :-X

LOL. If there was a kid that would pull that off, it would be Jamoz' kid.
My first did that 6 times per night (on average) for 22 straight months. I was literally sleeping at work during meetings. Good times ...

No reason why there can't be an FTP folder for this. I'll speak to Alibaskins

I will also look at converting over to .pkz also.

Thx ! It's getting pretty complex for new players: bikes + tyres, rider models + suits + helmet models + helmet paints ...
