F1 » Horner lays blame on McLaren ECU for Webber woes


With McLaren's technical standing taking a beating on track, now its their provision of the latest generation of ECUs that's under the spotlight.

Whom are we supposed to believe RBR or MES?.
RBR says MES supplied ECU was at fault while MES says the problem was inside the RBR garage telemetry.
If what MES is saying is the truth there might be illegal technical implications.
If the telemetry from the RB9 of Webber was at fault the car itself is not supposed to have been effected as telemetry (data acquisition) is supposed to be one way (from car to pit/garage) according to the rules, that rule has been in effect since mclaren was caught doing adjustments to the car from the pits.
Another thing, if the RB9 of Webber had a KERS failure at the start he would have been short of 80 hp but telemetry (data acquisition) in the garage/pit is not supposed to have affected his start and that includes his KERS.

Nonsense! Horner should know better than to play the public blame game after the first alleged failure in two years of a third party component. McLaren bid to be the supplier and have an excellent reliability record. To suggest foul play is childish and irresponsible. And if McLaren were to sabotage a driver's ECU, do you think they would choose Weber's? If he thinks Red Bull can do a better job then he should consider bidding on the contract when it comes up again. Oh right, Red Bull doesn't make electronics, or engines, or gearboxes for that matter.

benignly. first failure of a tp component???? were you not watching last year? rb had three failures of alternator supplied by a tp!

as regards the ecu issue, sunny, mes supply the software for the pit computer to receive the info from the car, so yes, they were responsible, and as i pointed out earlier, mes have said (through whitmarsh) that they are working with rbr to resolve the issue. now that sounds to me, like mes accepting blame, and they even went on to highlight the issues in testing, when THREE teams had the same problems.

as regards kers, it appears that as the ecu receives the enable code, the software prevented the ecu from switching on the system to harvest the power on the formation lap

Richard, according to the rule the data acquisition in the RBR garage/pit is supposed to be one way (from car to garage/PIT) so no signal or activation of any sort can happen from garage/pit to car.
The enable or disable of KERS is supposed to be triggered/done by the driver.
Defective software in the garage/pit data acquisition computer/s being only allowed to be one way from car to garage/pit should not affect any operation on the car.

@benignlyindifferent - I don't think that McLaren even know which team much less which driver each ECU will be supplied to for this very reason. Either way it seems like a major conflict of interest to have a team supply required parts for the other teams.

Well thats a new excuse for the book Christain. How about next time you design your own ecu. Dont blame other teams for your demise. The net draws ever closer in. Your days are numbered Red Bull!!!

sunny. the kers activation is part of the function of the ecu. that is why you see its activation on the tv screen. the fact that the software was not been transmitted/received, shows that control of the kers by the driver, was intefered with by the software.

kycz . i am sure that rbr could design and build an ecu if they wanted to, but the trouble with that idea is that it is an ecu designated by fia and produced by ONE contracted company, and which has to be used by ALL teams. that is to avoid teams producing software to input banned electronic controls such as traction control etc

the contracted company is a mclaren company, and whereas it might be fun to talk about sabotage, i would be 100% sure that the company is honest enough to provide exactly the same spec to all teams. these ecus are checked by stewards at each race.

For all of you conspiracy theorist. Why does RBR have to plague Webber with all the technical problems? especially at Australia where's his track record is already very poor.

Also, Webber is a known poor starter so why would they bother blaming it on the ECU if it wasn't true? There's nothing to gain by doing it.

For the KERS problems Webber always faces how about this? We all know Adrian Newey likes to pack his cars tight which limits cooling. Well what if the reason Webber is always having KERS ( and over hearing problems last year) is because he's simply "too big" for the car. Vettel's smaller size means he's a small proportion to the car than Webber is. So whereas Vettel takes up 40%(just a random number dont read into it) of the entire car, Webber takes up 45%(again just a random number) of the entire car. This means that Vettel has an extra 5% of space that can be dedicated to cooling the car. Or maybe the KERS and other parts of Vettels car aren't as tightly packed beca

"That's simply untrue. If you look at mechanical DNF's, Vettel has had six in the last four years compared to just one for Webber."

Mechanical DNFs maybe, but in terms of 'KERS related issues' Webber has BY FAR had the rough end of the stick. And they always seem to pop up when Webber is alongside Vettel on the front row or a chance to race seriously with him during the race.

It's as obvious as the nose on your face, Reb Bull are going to start looking really really silly if they keep trying to deny it.
