The FIA sensor is to measure peak flow as the rule says not average flow. I can't find in the regs where it says it must be by the FIA sensor. If RB can prove their sensor and readings meet the standard and rule they may win.

Formula One cars to clip playing cards to rear wheels The disappointing sound of the new engines in Formula One is to be addressed with the use of playing cards clipped to the rear wheels, according to Bernie Ecclestone this morning. With the move to V6 engines with electric power trains away from the previous V8 engines, the noise in the pit lane and around the track has been described as ‘disappointing’. Formula One supremo Ecclestone told reporters, “A Formula One experience is not complete without at least partial hearing loss and ongoing tinnitus issues.” “The roar of the old engines was almost enough to make your ears bleed, and that’s what the fans, teams and sponsors want.” “We have looked at the possibility of microphones and amplifiers around the engines, but we’ve decided that playing cards on the rear wheels will offer the significant enhancement to the engine acoustics that we’re looking for.” “We will be introducing a limit to the number of spokes allowed on the rear wheel to ensure no team has an unfair auditory advantage, though no doubt the creative teams will find a loophole in the regulations.” “Before long the clickety-clack of a formula One car speeding past will be as recognisable as I am.” Formula One engine noise Teams have already begun assessing the impact of the playing cards in their simulators and wind tunnels, with some feeling they have stolen a march on the competition. McLaren F1 spokesperson Simon Williams told us, “The small amount of extra drag we’ve experienced is more than made up for by the guttural sound from a playing card being thwacked at 190mph.” “We’ve found that casino grade cards give the best acoustic return, but card degradation is going to be an issue for all the teams trying to complete a race distance.” “It’s bad, but we’re just hoping Pirelli don’t move into the playing card business.”
Apparently the sensor is more than a monitoring nanny, and also restricts the flow proportionately down through the RPM range from this: Why F1 has fuel flow sensors in 2014James Allen on F1 – The official James Allen website on F1 // F1 News // James Allen on F1 – The official James Allen website on F1 http://www.jamesallenonf1.com/2014/03/why-f1-has-fuel-flow-sensors-in-2014/

Everything I've read has said that it's designed only to run an ultrasonic pulse between two transducers, and measure the timing of the pulses. No moving parts are involved specifically to not restrict the fuel. The rules are written so that there is a restricted fuel flow at lower revs than 10,000, but it's not the sensor that's doing that. If an engine is using 100kg/h at revs lower than 10,000, then they are in violation of the rules. So if the engine is at 9000 rpm, they can use up to 99kg/h of fuel, but no more until they reach 10,000~10,500. AND, they can't use more than 100kg/h at 10,500. 2014 F1 explained: How Formula 1 fuel flow meters work | Racecar Engineering BTW, I absolutely LOVE that we are still talking about the race, even if it is just going over minutia.
Here's a sound you probably couldn't hear in the V8 era, Tire Squeal! [ame="https://www.youtube.com/watch?v=L_ZY_WQJxb8"]Raikkonen Lock Up - AusGP P1 - YouTube[/ame]
Suzi Perry is joined by David Coulthard, Ben Edwards and Allan McNish to discuss a whole range of topics ahead of the new Formula 1 season. Here the team give their thoughts on how Kimi Raikkonen and Fernando Alonso will fare at Ferrari and feel there may be fireworks at Mercedes. They also look at the exciting pairing of Felipe Massa and Valtteri Bottas at Williams and who they think will be this season's top rookie.

Locked wheels under braking isn't caused by the new engines lack of sound. Locked wheels have always squealed. Or are you saying that harvesting is causing rear wheel lock, in which case yep it's the new power lump.
We couldn't hear the locked wheels before due to the engine noise. Without as much noise we hear more of the underlying sounds.
I have heard locked tires making that sound before these lumps. Yep it was a might harder to hear, but the sound was there.

Think Lauda nails it, turbo motors sound different than NA V8s.....it has to evolve. From motorsports: Mar.20 (GMM) It is "absurd" to suggest Formula One should urgently turn up the volume of the new turbo V6 engines. That is the view of Mercedes team chairman Niki Lauda, who days ago in Melbourne admitted the sound of the 22 cars charging to the first corner left him underwhelmed. Williams technical boss Pat Symonds agrees: "For me the start is the most exciting part of the race, and I loved it when the 22 drivers revved up their engines. "I don't generally complain about the sound, but at the start (in Melbourne) it did seem a bit quiet," he told Auto Motor und Sport. Lauda, however, said: "The debate about the engine noise is absurd -- you can't change that now. "It was decided by all parties five years ago that they wanted turbo engines, and so we put in a turbocharger before the exhaust. "It has a different sound, any child knows that," the great Austrian told Osterreich newspaper. "If you take the turbo away, you don't have hybrid engines anymore." As for the duller sound, "We have to get used to it," Lauda insisted. With a slightly more open attitude, however, is Lauda's Mercedes colleague Toto Wolff. "I'm not much of an engineer," he told Finland's Turun Sanomat newspaper. "These things will be looked at. "If it is decided that something must be done, then we would have to think about it carefully. "I would think that it is possible, but whether it is right, I don't know. "The V8 engines sounded fantastic, but I saw this race (Melbourne) up close and I can assure you that F1 is still the top of motor sports, it's not GP2. "This (move to V6) was the right step," Wolff insisted.
I thought Merc would have heat issues with the electric motor between the 2 turbo halves. Interesting change. The functional description is the electric motor on the turbo gets rid of lag. But what if they would actually spin the compressor faster, full throttle, than the exhaust is pushing it? More boost, more power and exhaust extraction.
Changing spec's to make the sound better or different would be ludicrous. Not a fan of the sound, but they are what they are. Yep we'll get used to it. Mercedes & Williams not wanting a change makes perfect sense. They have power plants that are working well. Don't rock the boat.
