2014 Testing - Jerez 28-31 Jan

And can they change maps during race? I mean do they have a few on them already preloaded?

yes

Not sure I agree with that. From what I've read, the regulations state that :

"5.5.3 The accelerator pedal shaping map in the ECU may only be linked to the type of the tyres fitted to the car: one map for use with dry-weather tyres and one map for use with intermediate or wet-weather tyres."

I take it to mean that each car may have multiple maps for use at different tracks, but that they are limited to one map for dry tires and one for intermediates/wet tires for a given race, which must be controlled solely by action of the accelerator pedal. So, no switching to various maps during the race, and no push-button activation a la KERS from last year allowed this year.

Looks like Pirelli hitted their targets. The winter tyre has been a very thankful solution for the teams, and they got some good running on the wet tyres.

Yep, clearly all that investment into rain dances has paid dividends. Was refreshing though to have an F1 event where the focus was on something other than Pirelli. Good job by them so far, let's hope the season carries on with them being in the background not the hot topic every weekend.

No, they are not allowed to tune per-race. This was adjusted a couple of seasons ago as it became clear that the teams were quickly iterating through hundreds of different engine maps to find the most blown downforce.

That rule is for the pedal map only. You can have only those two maps for torque demand, but you can have many different ERS maps which maps will define the avaliable torque. So you can request that torque from the engine with the pedal maps....at least that's how I think it works.

[Richard]

The pedal map is just for the signal from the pedal.

The teams have many different maps for different bits of the car, such as diff locks, fuel saving mode, and ERS mode. That's why the steering wheel is so complex. If they only had 2 maps then the wheel would only need a single toggle switch.

[Blanchimont]

The caterham steering wheel shows a turning knob that's labeled TORQUE in the middle and slightly to the left. Below this knob there seems to be another one that says ENERGY.

I believe this is correct.
How are you otherwise going to tell ERS you want to save the energy for 1 lap and then release max power on lap 2 for overtake? There will be "push to pass" maps for sure, it's just not going to be like we were used to with kers.

Probably a rotary button.

More on that subject: there were talks about running the cars only on electricity in the pits. That idea never got a regulatory foundation, but could the teams decide to do this on their own to save fuel? Could be a nice benefit.

I doubt it, not this year anyway.

The FIA said once the pit lane goes all-electric the cars need a warning device, like a sound beacon, to warn of their coming down the pit lane and I can't see any team doing this if they don't have to.

Also, what about engine starting? I would say they could use the MGU-K to do it, but that'd need some serious grunt and I just doubt they'll do it, this year anyway. .

serious grunt? the mgu-k must be linked to the crank shaft so it doesn't even have to drive the car at the same time
you doubt that 160hp mgu-k can do it? The hand held starter they use runs on 24V I doubt it is a tenth of that power

[Xero]

Also, correct me if I'm wrong, but isn't there regulations in place so that cars must discharge the ERS before being turned off? If that was the case there would be insufficient power to start the car. Again, I just pulled that from the depths of my muddled brain, could be wrong.

A look at the 2014 steering wheel displays we saw in Jerez



I also made a thread about it here if you feel like talking about it: http://www.f1technical.net/forum/viewto ... =4&t=17860

There's a lot on that display that doesn't seem very useful to drivers. I mean, do you really need to display RPM three different ways on one screen? And when is anyone going to look at those graphs? The drivers have much better displays available to them when they're in the pits.

I'm going to assume that the teams can customize it all though.

The lap counter is nice, and the last lap time.

A few things I think I'd like as a driver:

Laps remaining/laps until next pit stop
Target lap delta
Time to car ahead/behind
Tire temp

And a twitter feed, of course.

it's a $20 display and a $10 micro, it should be able to show anything the driver desires assuming they can find
someone to program it

Except time to car ahead/behind, those are things they wouldn't like to show to the other teams for sure.
