I guess the FiA wants one homologated system for all competitors. It helps when malfunctions occur because they would be the same for all. Sporting equity and less options for cheating.

Anybody to try to add such a system will have to be very careful as it is explicitly forbidden.

5.10.5 Any device, system or procedure the purpose and/or effect of which is to increase the flow rate after the measurement point is prohibited.

And if you read through § 5.10.1 and 5.10.2, the sentence

Only approved parts may be used and the list of parts approved by the FIA, and the approval procedure, may be found in the Appendix to the Technical Regulations.

shows that the FIA will strictly monitor the fuel system to avoid any cheating with the fuel flow rate.

Haven't read the regulations closely. But yes these paragraphs does prohibit such a system.

5.10.3
Homologated sensors must be fitted which directly measure the pressure, the temperature and the flow of the fuel supplied to the injectors, these signals must be supplied to the FIA data logger.

I think the FIA will check the fuel used in the race in the post race scrutineering, only the teams will monitor their fuel consumption live during the race.

It depends what you mean by online. It will certainly be cumulatively monitored on the car internal network and logged in the FiA data logger for later read out. Will it be transmitted and monitored at race control? Technically feasible and even likely because the data logger could malfunction or be destroyed.

Anyone knows anything about Ferrari or Mercedes?? When Renault showed pictures of their V6 months ago Mercedes was soon to follow. But after Renault showed the real engine nothing has been heard or seen from either Mercedes or Ferrari.

The impression from Marmorini's press talk is that Ferrari are behind in terms of project milestones.

I didn't get the impression that they are behind. I just herd him bitching about the 100kg limit. But i just took that as Ferrari standards.

As Ferrari traditionally been an engine with four wheels around it, I'd be surprised if so.

I figure that all manufcturers are sandbagging at the moment, most of all Honda, minimum weight and CoG, that leaves some room for intrepertation, doesn't it?

We have been working for some time to have this car ready but it’s a challenging task. Only at the first race next year will we see if we have done a good job.

That does not sound like they are comfortable in the time plan. In actual fact it sounds like they are stretched.

Or that designing, testing, revising, finalizing, and manufacturing a competitive 1.6L turbo engine and the associated energy recovery systems is, you know, difficult.

But isn´t the ECU already a homologated system used by everyone?

Why having PURE poing the legwork could be useful

System in this context was referring to the fuel flow measuring and control sub system. Obviously the ECU is a homologated, standardized, distrubuted on car network with a number of dedicated CPU's all running with homologated Software. That system is not going to change as it was updated this season ahead of the big change next years. The fuel flow technology and various other bits like the brake control, the energy management, the turbo and MGU-H management will all be added to the ECU system. All these functions can be done by dedicated sub systems and therefore we may refer to them as systems.
