After a day or so of testing, I figured out a weird problem with the traction control setting of the Oreca LMP2. When setting TC to 8 (max setting), the throttle input max will be capped at around 70-75% of its max, regardless of what the real throttle input value is. Video demonstrating the problem: Decreasing the TC setting to anything lower than 8 causes the throttle max input to go back to 100%. Not sure if it's intended, but it gave me quite some headaches...
Had the same issue in our league race in the wet at Spa. Max TC seemed logical, but you could loose multiple seconds per lap. Some LMP2 drivers struggled to get past the GTEs because of this. Edit: I'm not sure if it's a bug or that it's meant this
That could be intended, if the MAX traction control is required by conditions, then the computer may also cut the throttle to aid in car control.
