Title: Engine mappings
Post by: PeterV on August 12, 2014, 07:12:53 AM
I wonder if we could get it setup for the GP1000 class so that Qualifying mapping is only available in Qualifying and/or Practice sessions.
So NO Qualifying mapping in a race. Maybe an option to have for a server admin or through the dedicated.ini?

I really don't know if a qualifying mapping is available in the real MotoGP during a race, if so enlighten me Obi Wans.

I agree there needs to be a way to have of during a race. :)

i think its a case of fuel.. it wouldnt last race distance!
does a full tank of fuel last a full distance race on gpbikes on qualify mapping?

Depends on the amount of laps in the race and which bike for instance V594 21ltr. YZR 33 ltr.
And you can also alter the amount of laps for a 100% race if you would like too.

Like you said, it depends... In modern MotoGP, the factory bikes in all likelihood wouldn't last a full race distance on max qualify mapping. For the CRT-bikes or whatever they are called now, they have less consumption and are also allowed more fuel - so for them it might work out or at least they could use a mapping that is closer to the pure qualify mapping.

But imo, the mapping settings in the garage should be tweaked anyhow. It should be possible to adjust it to whatever power output possible - at the cost of having higher fuel consumption. So e.g. so I could ride with 100% power output in qualifying and e.g. 95% of maximum power output in race on track A and 97% power output on track B because on track B has a shorter race length or sth like that. I think you know where I am getting at. It should also be possible to adjust this "on the fly" during races like it is now with the pre-defined engine mappings. It would also be good however, if it was possible to select certain TC and AW settings on the fly. As this would result in an enermous amount of different possible settings - the rider should be able to save certain settings of [engine mapping (in % of max power), TC, AW] as predefined settings to choose from. Those defined bike settings could be saved with the setup.

Hmm, I agree with Stout for onboard settings for TC and AW (maybe even Engine Brake), but I'm less hot on custom maps, as they are not as simple as "a % of the full power".

Sorry to disagree but the engine mapping take no effect on the fuel consumption (unfortunately) in GPB.
In real life it does indeed  ;D

no no.. we agree!  :)
bottom centence was a question  ;)

Sorry if i don't understand well, but i'm sure that if i use qualif mapping the consumation of fuel is bigger than the other mapping.

True. Whenever I tested it for race simulations I also experienced that the fuel consumption was higher for qualify mapping - that's how I recall it. Can you specify your thoughts C21?

When we did try Monza track way way back  ;D in the day of GPBikes, we tested a lot and changing from normal maps 1&2 to Qualifying map
and it certaiinly did raise the consumption of the fuelrate.

Ok.
My assumption was based on the cfg of the bike.
There you have to specify the Fuel Ratio which is a fixed term.
To be honest i´ve never tested the Fuel consumption with different maps.....
No i know that i was wrong.
Thank you.

Yep, the fuel ratio is the same no matter the mapping, but we don't know what the fuel ratio is exactly (how it is used to compute the fuel usage) so depending on what it is exactly, the mapping may make a difference (as PeterV, Stout and janaucarre are reporting above). I think I asked once for details but got no reply.

Yes I remember that as well with probably the same Monza race. It was not possible to complete the full race on quali mapping so everyone had to start on race mapping and possibly change it somewhere during the race. I am really confident that the mapping has influence of fuel consumption, at least it did back then and probably still does now.

When using quali mapping, the higher revs may be one of the factors that influence fuel consumption. As the fuel ratio may only indicate the base fuel consumption for that particular engine/bike, and the amount of revs influence fuel consumption, increased revs seems like a probable part of influence on the fuel consumption.

Hmm, I'm not 100% sure that (in GPB) the map makes a difference on the highest revs you can hit. For sure it does at the end of a long straight (last gear, top speed), but not elsewhere. I'd think that in any gear but 6th, you can hit the limiter with any map.

I think that the "fuel ratio" is not tied to the RPMs but to something else, maybe the power at the crankshaft (as different maps do have different power outputs).

We could make some tests: go on Oval track, check the fuel usage on a given map on a lap at constant RPMs, then edit the map lowering the power curve (e.g. half) and do the same test, at same RPMs. If the fuel ratio is tied to the RPMs, the fuel usage should be identical despite the fact power (and speed) are different.

Anyway, would be much easier if Piboso told us :)
(I mean how the fuel consumption is computed, the fact that the maps influence the fuel usage seems to be clear)

MaX.
