Technically who's fault is it? The pit crew?

[Morgan]

Was wondering the same thing...

 

Did he ask for extra fuel pressure?

 

Did they tell him to do it?

It would have to be the pit crew.

If the fuel mapping allows more than the legal amount of fuel flow, that's not something he can do from the cockpit (heh, cock.) mid-race. The tuners should have picked it up.

Sucks.

Hamilton's save.

Interesting.

F1 tweeted a short while ago that it may have been incorrect monitoring that gave the "offending" reading from his fuel flow and that is the basis for Red Bull's protest.

Someone who knows more than me has deciphered what they're saying...

"The fuel flow sensor takes readings of the instantaneous fuel flow at a certain speed. Originally it looks like the spec outlined that the readings be taken 10 times a second (10hz), but but that there had been a change to lower the read speed to 5 times a second.
Because there wasn't time to change the actual ECU setup prior to the race, the system will continue to monitor at 10hz, but after the race the FIA will chop out every 2nd data point to make it 5hz only.
The upshot of it all is that, with the slower read speeds, if the car is only spiking above the flow limit very briefly (Or the sensor has a noise issue that causes these types of spikes), it is very slightly less likely to be picked up by the sensor. If the car was going above the limit and staying there for more than 200ms though, it is still a certainty that it will be picked up."

Thats the kind of stuff ten should have be broadcasting about, not all the other crap

Another interesting document regarding parts changed on car 03.

I wonder if RBR got caught out??

And here is a pretty comprehensive breakdown of exactly what the stewards found (and reported).

http://www.f1times.c...s/display/08637

1) The Technical Delegate reported to the Stewards that Car 3 exceeded the required fuel mass flow of 100kg/h. (Article 5.1.4 of the Formula One Technical Regulations)

2) This parameter is outside of the control of the driver, Daniel Ricciardo.

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.

4) The stewards considered the history of the fitted fuel flow sensor, as described by the team and the Technical Delegate’s representative who administers the program. Their description of the history of the sensor matches.
a. During Practice 1 a difference in reading between the first three and Run 4 was detected. The same readings as Run 4 were observed throughout Practice 2.
b. The team used a different sensor on Saturday but did not get readings that were satisfactory to them or the FIA, so they were instructed to change the sensor within Parc Ferme on Saturday night.
c. They operated the original sensor during the race, which provided the same readings as Run 4 of Practice 1, and Practice 2.

5) The Stewards heard from the technical representative that when the sensor was installed on Saturday night, he instructed the team to apply an offset to their fuel flow such that the fuel flow would have been legal. He presented an email to the stewards that verified his instruction.

6) The technical representative stated to the Stewards that there is variation in the sensors. However, the sensors fall within a known range, and are individually calibrated. They then become the standard which the teams must use for their fuel flow.

7) The team stated that based on the difference observed between the two readings in P1, they considered the fuel flow sensor to be unreliable. Therefore, for the start of the race they chose to use their internal fuel flow model, rather than the values provided by the sensor, with the required offset.

8) Technical Directive 016­14 (1 March 2014) provides the methodology by which the sensor will be used, and, should the sensor fail, the method by which the alternate model could be used.
a. The Technical Directive starts by stating: “The homologated fuel flow sensor will be the primary measurement of the fuel flow and will be used to check compliance with Articles 5.1.4 and 5.1.5 of the F1 Technical Regulations…” This is in conformity with Articles 5.10.3 and 5.10.4 of the Technical Regulations.
b. The Technical Directive goes on to state: “If at any time WE consider that the sensor has an issue which has not been detected by the system WE will communicate this to the team concerned and switch to a backup system” (emphasis added.)
c. The backup system is the calculated fuel flow model with a correction factor decided by the FIA.

9) The FIA technical representative observed thought the telemetry during the race that the fuel flow was too high and contacted the team, giving them the opportunity to follow his previous instruction, and reduce the fuel flow such that it was within the limit, as measured by the homologated sensor – and thus gave the team the opportunity to be within compliance. The team chose not to make this correction.

10) Under Art. 3.2 of the Sporting Regulations it is the duty of the team to ensure compliance with the Technical Regulations throughout the Event. Thus the Stewards find that:
A) The team chose to run the car using their fuel flow model, without direction from the FIA. This is a violation of the procedure within TD/ 016­14.
B ) That although the sensor showed a difference in readings between runs in P1, it remains the homologated and required sensor against which the team is obliged to measure their fuel flow, unless given permission by the FIA to do otherwise.
C) The Stewards were satisfied by the explanation of the technical representative that by making an adjustment as instructed, the team could have run within the allowable fuel flow.
D) That regardless of the team’s assertion that the sensor was fault, it is not within their discretion to run a different fuel flow measurement method without the permission of the FIA.

Didn't you like hearing about how to make cupcakes (some cooking judge asking to trade his Nico sweep stake for Button no less) or what Paula Abdul and some other drag queen likes about being judges on Australia's got a millionaire dancer chef?

I was tripping balls though...
