For anybody who hasn't used the Enduracers mod before, all GTE and P2 cars have in-car Traction Control and engine Boost adjustment, so make sure to set either a wheel button or keyboard key for them in your controller settings. Traction Control range is 1-12, where 1 is Low and 12 is High Boost Adjustment - 1 is high and 4 is low
Take what I said above about Boost with a pinch of salt and do your own checks. After some practice laps it appears to be that Boost 1 is LOW and Boost 4 is HIGH, at least in terms of fuel consumption anyway. I'm not massively different on lap time with either setting, yes a bit, but not a big difference. Maybe I was thinking of rF1 Enduracers or maybe another similar mod, ILMS maybe?
