Red Bull exceed fuel flow limit, Ricciardo DSQ at Australian GP

For ease of use, there is one thread per grand prix where you can discuss everything during that specific GP weekend. You can find these threads here.

Because Red Bull would claim that theirs is too small, drill it out, and claim that their drill bits are more precise than the FIA's. :lol:

There will be no battle at the front:

This is shaping up to be the dullest season of possibly all times.
Actually they are fully free to race as Toto pointed out many times even pointing out that they have already done this many many times in the past.

What they are talking about there is special cases.

Also note:

"We were caught out by surprise last year in Malaysia and we don’t want this to happen again."

Meaning if the same scenario happens, Rosberg goes past plain and simple.

These sensors DO NOT work the same for everyone.... or they would not need a correction factor issued DURING the race. How does the FIA or the sensor manufacture know if a unit is accurate during the race? Again, RB's approach is a no brainer. They are bring to public light the unresolved issue with the fuel flow meters.

Indeed it is a no brainer – that is to say, they had no brain in using it.

The rules are very clear. If the FIA's sensor says you used too much fuel, you used too much fuel. RedBull were idiots to pay attention to any sensor other than the FIA's. All the other teams followed the FIA's advice, and ran leaner. RedBull should not be an exception.

If I'd doubt the sensor was faulty and I'd the chance to replace it I'd just do that. Besides that I just can't image that many sensors are faulty. It can always happen, but chances are small.

With my limited knowledge and from what I've read I don't think it is that hard to fraud with the system. From what I've read the sensor is able to measure at 100 Hz and FIA is using a lowpass filter at 5 Hz. This is in my opinion is a very low frequency to if the primary goal is to prevent the peak usage. I don't know about the details of the measuring but there are two possibilities. Either the sampling is done by the same system or it is done by a different system. Knowing that the teams have access to the data they must be able to correlate that with their own system easilly. The trick is to have the flow happen at a higher frequency than the sampling in such a way that the FIA measurement is aliasing.

to draw a parallel with somthing everybody knows: the backspinning wheel of a filmed driving car. You know the FIA is filming at 24Hz. If you drive at the correct speed they'll think you stand still, or even drive backwards.

The better the correlation the easier to fraud. If the correlation is worse it just means you can fraud less, for a smaller period of time, but you can still do it. IMHO the only requirement is to be able to modulate the flow faster than 100Hz, which probably is not impossible.

Any thoughts pro contra this idea?
I'm not sure I completely get your point but I don't think you can cheat this way. If you could the FIA wouldn't have found out. It's all about the peaks in fuel flow. The FIA has provided a metric to measure those. Red Bull decided that this metric doesn't suit them and used their own which gave them an advantage.

I don't get this "is it faulty or not" arguing. There are independent calibration companies - FIA and RB just have to give them the damn sensor with some fuel and wait for the answer. I believe the fuel flow meter could be recalibrated as all measuring devices has it's own procedure to calibrate. In that process you do exactly what we're asking here > you determine ( map ) the whole measuring range of the device - and you'll get an error map. It will be clear after that is it a faulty sensor at all - and by how much. I can't imagine it will take longer than 2-3 days for an experienced company to do that.
What prevents them doing that ? ...Maybe in this case it really doesn't matter if it was faulty or not, but the check would calm down some emotions either way.

Precisely. There is no "objective" fuel flow rate - what the FIA sensor tells you is what matters.

I think this is the first thing you've ever posted I agree with, albeit probably not in the way you meant.

Wrong... You break the rules when the fuel rate is too high. No rule states 'when the homologated sensor records a too high fuel flow rate'.

They already know the unit is out of calibration by the FACT that they issued a correction factor to RB during the race to use.

Quoting the stewards:
"3) The fuel flow is measured using the fuel flow sensor (Art. 5.10.3 & 5.10.4 of the Technical Regulations) which is homologated by the FIA and owned and operated by the team."

And you don't see how this undermines all of your trolling, sorry, arguments? Specifically the fact that RBR ignored it, and you have no idea what factor (if any) was issued to other teams.

So now the teams are going to base their engine setups on what a faulty designed meter allows? Sounds like real crap shut to me.

The teams are going to base their engine setups on what the sensor specified in the rules tells them, yes.

This is what every single team other than RBR did this weekend, and it worked out just fine for them.
