Setup and Data for the Oreca LMP2 (Gen2) on Interlagos in AMS2

LMP2
The most interesting part on almost any car surely is the differential, which allows you to adjust the car in all potential cornering phases. 

Here I dialed it in so that the rear would rotate on entry, but just about not step out too much, while on exit you will feel it gripping up and pulling itself more to the inside. With more fuel, you'll likely want to check the balance and potentially counter the resulting oversteer with either a click of wing on the rear or lowering the rear ride height further. Other than that there should not be more changes from Q to Race, unless its hot temperatures and you want to go for the harder compound.

Interlagos
Interlagos is special because of its long deceleration into slow turns while already having to turn under braking. This is extremely difficult for your left foot and a great challenge and practice ground. As little as 5% brake can be enough to lock up the tire. So you need to make sure to find straight braking lines by sometimes going diagonal towards the outside turn in point to not unload the inside tire too much when still requiring hard braking. Make sure compromises are exit focused when there are several turns in a row. Its working the rear right tire a lot, so might have to switch to HARD compound for the race!

Driving

• Initial braking can be harsh, but needs trailing off the brake right after as the downforce quickly drops
• unless you throw the car in too harsh the car will be stable to understeer when coasting - that means you want to be back on throttle as soon as you are off the brake and the car will keep rotating
• TC1 is fine, but for ultimate laptime, turn it off for the fast corners, as it still engages too much

Adjustments

• start with the differential if any behavior is not to your liking. Less coast degree for more stability into the turn. More power degree for less oversteer on exit
• remove front wing if car is too aggressive in fast turns for you (or add rear wing)
• if slower corners are too sketchy, stiffen front roll bar (small impact), also more coast locking (lower degree or more preload) help here
• of course adjust brake bias to the front if car is difficult under braking, but I feel its already quite far forward

Fuel

In Q the car needs about 2.3 L per lap. Likely a little more in the race as the straights become "longer". Calculating with 2.5 per lap should be more than safe. 

For the race I'm expecting the balance to be slightly forward with fuel, so perhaps already account for that with the changes above.
