ERS management

What means BBsl on the steering wheel?
And is it possible to know what value we are running (MGU-K, MGU-H, brake engine)? Instead of clicking on MGUK Recovery + or - to know what was the value... Is there a widget or something?

 

If done some testing with engine brake and if it has an effect on fuel consumption.

I used the standard stetting, so "balanced low" MGU-K delivery, MGU-K recovery "5" and MGU-H "battery".
I drove a couple of laps on Nürburgring GP with engine brake set to "1" and "13", but I couldn't feel any difference in stability or fuel consumption. With both settings I ran 2.48 to 2,50 l/lap for several laps.
But since I could feel stability differences maybe the other settings were to conservative with too little ERS usage (power and recovery).

Maybe I will do some more testing, but the speed of the SF15T is just exusting, mainly for the mind. So for now I need a break from it.

 

Ok ok thank you very much! I didn't see it!

And thank you for your AMAZING job!! Those cars are fantastic!

When I switch MGU-mode, at the top of the screen it's written MGU-mode battery or motor, but I can see thanks to the ERS managment app that it switches MGU-K delivery as well as MGU-K recovery and engine brake...
The values are always changing when I switch profiles when I'm driving...
I don't fully understand... is it a normal behavior?

Theres a bug with Engine Brake 1; try 13 and 2, there should be a big difference!

 

OK, will try it again with those settings.

But after having experienced this hybrid system, I now how far more respect for the F1 drivers of these cars, in addition to the forces the endure, racing against opponents while managing fuel and tires.
And the probably have several more settings to work out like fuel mixture, diff-setting, etc.

 

So I tested the engine brake settings a bit more, switched between 2 and 12 (of 13), again on Nürburgring GP.

I used balanced low for MGU-K delivery, MGU-H to battery and aimed for SOC in the range of 30-60%.
With engine brake at 2 i switch MGU-K recovery between 40% and 50% and with engine brake to 12 I left MGU-K rec. at 50%. This was because with brake to 12 the brake distance is a bit shorter and therefore less harvesting. With the higher engine brake the rear was a bit less stable, but not an issue. Maybe with higher MGU-K recovery and/or brake bias to rear it might be more pronounced.
I can't say how engine brake effects tyre deg., because for consistency I deactivated it.
Lap times were comparable with in a margine of error, I think mostly me as main cause for that

So, now to fuel consumption, which was the point why I tested this.

With engine brake to 2 the fuel use was consistantly in a range of 2.52-2.57l/lap, I'd say on average it's 2.55l/lap, with about 8-10 clean laps or only minor driving errors.

With engine brake t0 12 there was almost no range, basicly all significant laps were 2.46-2.47l/lap, with maybe 2 less laps driven in this setup. Less laps because results were very consistant.

So this means the difference in fuel use per lap is roughly 3% or 0.08l/lap on Nürburgring GP.

I would have expected about 1%, maybe a bit more, max. 2%, but a little over 3% is a bigger difference than I thought.

 

Thanks Phil for this explanation, that all makes perfect sense to me. I can see where my interpretation is completely wrong and has got me mixed up. When it comes to engine braking modes I have always considered more is less & vice versa. I assumed the more the throttle body remains open whilst braking the more engine braking that was being applied. I guess i associated this with using a lower gear with higher rev range for going down hills. I was wrong and am happy i learnt its correct meaning.

Great. thank you for the link. It should be an interesting read.
