So I figured out how to make the e85 LUA, I also figured out how to make the car run on e85 with having to build another engine, I can be done by requesting E85 Fuel in the ecu. This game is so intricate!!! Now I’m trying to figure out how to make an e85 lua that will work with the game. Has anybody had any luck doing this or can point me in the direction of how to do it?
