World's Fastest Stelvio?

[GTM®]

Check my Max MPH when I got home today. :huh:

 

[BravoBravo]

Were you out on the Salt Flats?

:lol:

So which rod came out first? The left one or the right one????

This rocket mod worked at last!

 

[Spaceclam]

At least it's not completely upside down, or working in slow motion...

And I thought I was fast at 159mph in the wet on a 60mph limit road..........it's amazing how heavy rain affects the power of these bikes.........well the speed sensor anyway!

Was your speed achieved in the wet by any chance?

 

[Forseti]

I wish I had caught mine when the speed sensor went.. showed 500Km/Hr plus for a fraction of a sec. :lol:

I suppose bad dashboard programming - It should record multiple samples and determining noise spikes messing with the speed sensor signal instead of reading them as real speed. It could even associate wheel speed with rpm & selected gear.
I think most modern bikes do not reed speed at the wheel but at the secondary gearbox axle so less cables going around, much less noise spikes.
As the the rear wheel is recorded, a lot of distance recorded is placebo because of the wheel slipping particularly when accelerating at low speed on mountain roads. The wheel is always slipping a little on power even if it is by just 1%-2% percent, too little to feel it.

It's little over a week you have the bike ....... and you just had to modify it with NOS ?
Nice :!:

 

[Spaceclam]

it DOES take multiple samples. That's why the dash takes forever to update the speed.

 

[Mi_ka]

Then they messed up elsewhere in the program - I am always angry to see bad code going for sale.

If you have been to Todd's house in Malibu, his long ass driveway is about a 45 degree downslope, easy to hit 176 just going to his house, heck, my eldo hit 150.... (seriously, last year, I had to put my ford F150 into 4 wheel drive to get up his drive way in reverse, it was just spinning its tires..... The most likely place to crash in the Santa Monica Mountains is pulling into and out of Todd's place. Watching roper take a tall stelvio up the drive was heart pounding....

Now, you wouldn't want a maximum speed recording that always worked, would you? There is an optimum rate of fail for this feature.

It should work most of the time, so you got the benefit of it; but it should also fail sufficiently often to be able to establish "reasonable doubt", in court

Joking aside, how does the speed sensor work, now they've got rid of the old fashioned front spindle gearbox & cable? I once had a pushbike speedometer that would read about 90mph every time I went over a particular set of those induction coils they bury in the road to control traffic signals. You'd like to think Guzzi don't use anything as sensitive to interference....

 

[Forseti]

Joking aside, how does the speed sensor work,

There is a "hall effect" non contact electronic pickup mounted on the carc that senses when the bolts that hold the brake disk go by.

They are prone to getting wet thus causing false readings and then failing.

 

[Mi_ka]

Hmmm, hall effect sensors affected by the induction coils used in the road surface... That could be an explanation as they could induce an alternating magnetic field through the bolt when it is in front of the sensor that could mess things up..

I think that's what my V7C has (though it doesn't have a maximum speed function, so I'd be less likely to notice any weird readings)

What happens if you fit stainless disk bolts..?

 

[Mi_ka]

Any ferromagnetic item close enough (usually <2mm) can be sensed by such sensors.
Steel is ferromagnetic.
