Does Red Bull have some sort of TC?

He might be stabbing the throttle. Ayrton Senna was also notorious for this.

 

He can do it that fast?

 

Nope, he cannot. This is being discussed heavily by a number of people on F1technical.

 

Isn't it just undulations on the road? I've seen cars do this before....just not F1 or on a track

Need to see what the others do too, I guess.

 

I've seen recorded data from Senna - he was sort of amplitude modulating the pedal at 8Hz (!!!) throughout the race! The engineer who showed us the data said he never saw anything like that with any other driver before or after...

 

That is very odd.

 

Without wishing to defend RB I seem to recall suggestions that the grip of current F1 cars is such that the tarmac surface gets pulled up - might the track not be flat and hence the car taking off and skipping to some extent - given its out of a low speed corner its surely a possibility ?

 

Rubbish.

 

Is it possible to add functions to the standard ECU anyway?

 

No.

 

Case closed, as long as there isn't any programmable brake ECU.

 

I can not see how to implement this if you can not modify or add any functions to the ECU. The engine blown diffusor concepts required only a change of the engine maps for one defined operation point (-> overrun) and steady operation.
A traction control is a pretty complex control system including feedback loops. It needs a bunch of sensor data, first and foremost wheelspeeds, and has to work under highly dynamic conditions. IMHO it's impossible to implement a TC by tinkering with engine maps.

 

As I said there's a difference between some sort of a feed-forward control based on engine mappings and a full-blown feedback control which would be required for a TC that deserves its name. There is only so much you can do by modifying the data and not the underlying functions, and I fail to see how a TC could fit in there.

 

Why would he be stabbing the throttle heading onto the straightaway?

 

No it's not. They've often ripped up the track surface over the years. Canada a while back was the last I recall(?) Admittedly under lateral load rather than acceleration, but they can certainly pull the surface up.

Not that I think that's what we're looking at here though.

I certainly don't know, but it almost looks like he's simply driven thru something (notice the line across the track) and its scrubbing off. Or it's a little washboard?

As someone noted, would like to see other shots at the same spot.

Red Bull cheat? Never

 

+1

And no need to be humble about it either IMHO!

Further, the rules are now pretty explicit on the topic - Ever since the Benetton 'we had it but never used it' debacle Charlie has been saving checksums of all the code. You change a single byte, he knows...... Even easier now with the standard ECU of course.

? Your point?

We know they're all messing, all the time, with engine maps. That's a *long* way from anything to do with TC.
