so i feel like taking fresh tires every pitstop is worth it. how does everyone else think of this? and what will we be doing in the race?

Yeah Sam. It's pretty much a for sure thing that's we take tires every stop. Especially considering that, even though it's not confirmed, it's likely we'll be in warm, afternoon default weather.

I'll have the driver schedule up tomorrow in line with Noel's fuel schedule.

 

[Daunt]

Hey guys, here's the schedule. Let me know if you have any issues.

You will find everything you need there, including links to the fuel sheet and the highlights sheet. Updating the OP as well.

lookin good!

i noticed there's no spotter/codriver in the first 2 stints. i'd be willing to do it if we need anyone.

Thanks Sam. I put it that way because I figured pretty much EVERYONE would be around at that point.

Some interesting iRacing threads that one of us should add to probably:
Screenshots of paints
Le Mans stream list

ok, so i just did a double stint on a track realistic to the last hours of le mans:
90% track usage and default weather (55% humidity and 26C air).
it felt a bit slower than usual probably because of the 90% track usage, but i don't know what any of these settings are supposed to do to my lap times

the one thing i wanted to bring to everyone's attention is my fuel problems.
i finished my first stint (13 laps) with 0.0 liters of fuel left when i reached my pitbox. yes, you read that right... i had to hit the clutch and let the car coast into the pitstall. on my second stint i pitted in on lap 12 because i had 6 liters left at pit-entry so i wasn't going to make lap 13 with that fuel.

maybe it was my driving, maybe it was the air temperature (i read somewhere it affects your fuel consumption) but is this normal? because according to our fuel scheme, i am not supposed to use this much fuel. so is it bad that i use slightly more?

if the calculations are really supposed to be this precise. maybe it would be best to run some scheme with a little less risk during the race.


-edit: i just read our fuel scheme again and it is really precise. for example pitstop #9 happens at 0.1 liters left in the tank. is it possible to plan this much forward for fuel?

Thanks Kyle! Stellar work, just one thing. There is no "e" in Colman. I know, thats how every other Colman on the planet spells it except my family.

You're right, it is quite precise to fit 13 laps in a stint. I probably can't do it either at full pace, might have to lift a bit.

I made it this way because the fuel data I got from Marc and Kyle indicated that 13 laps would be easy to do.

In the race it should be a little easier to do 13 laps because of all the traffic. Traffic means you have to lift more than you would on your normal line. Also, if we get damaged and lose time we have to do 1 less lap for every ~4 minutes worth of damage.

I ran my program again to see what shows up for a more lenient schedule. If we do a maximum of 12 laps per stint we would have 29 stops instead of 27. We would only use 93% of the tank capacity if we do 12 laps.

In the race, if you're worried about making it on fuel, we have end-of-lap fuel numbers for each lap that you need to aim for, which can be given to you by the co-driver.

BTW, we're using the Distributed (no saving) strategy on the spreadsheet.

 

[Jes_971]

Some fuel info. Probably not needed now but just to show my numbers in case of
anomalies. All were in Proto GT official race conditions.

 

[Noodleguitar]

Thanks Jes, that's helpful. It looks like you are just on the edge of making 13 laps without being careful.

I'll have to wait for the weather to be announced to see what our average lap times will be. If the team average is far off 3m55s then the schedule might change a little, should be no more than 1-2 laps I think.

Sam, were you doing those 2 test stints in default Afternoon? I predicted that we'd use less fuel in slippery conditions but I'm not sure if that's right.

i was doing it on IRacing default weather in late afternoon, not afternoon. does that chance fuel usage?

and it is good to know that the codriver is responsible for keeping track of fuel. i didn't spin in my 2 stints, but the one time i nearly did was because i was worrying about my fuel

I'm not sure it will affect fuel yardage usage or not but it will have a big effect on lap times. We're still not sure though what the time of day will be

Yeah, it usually goes like this: "Yeah you're completely fine on fuel" until about 5 minutes left in the stint and then it's: "Oh, sorry, you actually need to save 10 L to make it".

 

[Daunt]

I think I will be on tonight to turn some more laps if anyone wants to join.

@Duke Any word on our paint? I know you've been extremely busy with work these past few days.

It's not done yet but getting close.

My apologies but I've had some very personal issues to deal with and haven't had the time available I thought I would.

...nor the desire, sorry.

I have just about all the core done and still have yet to add the official sponsors.

It will be done shortly.

 

[little P]

Hope the RL stuff gets sorted soon dude. That comes first. Keep your chin up!

 

[Noodleguitar]

I might be up for some laps tonight. I am also seeing if I can get a Mid-Ohio race in for my participation.

Thanks P

Preliminary work is all done on the 2016 LeMans Aston Martin. I've uploaded the file to the server so you guys can try it out and let me know if there are any changes to make. Please note, a LOT of work went into this so I can only make small changes at this time.

Driver names will be added later in the week.

File can be dl'd from here: http://bandofothersgaming.com/files/downloads/iRacing/aston/2016-Aston-24hr-LeMans.tga

Apologies for the location, I had no LeMans stuff recorded so Watkins will have to suffice:

 

[Daunt]

Great job ken, thanks a lot! I will take some more screens in our practice right now. Also will load as decal layer. Great work! Love the hood especially. Tough to put sponsors on that thing but it turned out real good.

For decal layer during the race, place the paint in your proper folder and name "team_decal_58577"

 

[Noodleguitar]

Setup updated slightly, should make it a little more stable over bumps, thanks to Sam.
