Sure, it´s pretty simple, and I think I will release these tweaks as a perfomance mod, because it is so much fun.
Regarding fuel, I edited the values so that lean, normal and rich have the same performance as rich, but still the original fuel drain. I do this so I still can drain or save fuel if I want. I start the race with the default fuel load and choose rich because I think thats what the A.I. does, and it means (in therory) that I and the AI have same amount of weight.
Regarding ERS, I edited the values so harvisting is pretty much instant, I,e, taking away that from the game as close a I could.
Then I edited the values so 0,1,2,3 and 4 have the same performance as 3 i.e. "high". 5 "hotlap" is unchanged.
A.I. only run level 1-4 apart from 1-2 laps from the end where they switch to 5 "hotlap".
This mod works good because 5 is still default so qualifying have the right amount of speed.
And I only use mode 5 1-2 from the end because the a.i. do so.
All in all, much better racing , not so much slipstream/DRS trains anymore. No more a.i. using mode 4 performance only after being overtaken.
A bit less a.i. overtaking other a.i. sadly.
