I am using a T500 with the F1 rim. I assigned a button to the left menu (or whatever they call it, the thing to bring over tires and Fuel mix) and then one rotary to select between the two options and the same button to select the right mix. I can easily select the Mix 3 or 1 from Mix 2, but from that point on I cannot return to Mix 2 no matter what I did. At first I thought it was because I was using the rotary wheel but then I assigned the up and down to regular buttons. Same thing. Once I change mix that's it. I don't understand why Codemaster didn't imply let you assign 3 buttons to each mix. I mean, we are driving an F1 car and I have to press 3 buttons to select my mix? But that it is not working it's frustrating. Yesterday I was doing a 50% race in legend. I was in second place and I was stuck going back and forth between Mix 1 and 3. Mix 1 I was getting chased, mix 3 I would pull away but I was getting fuel alerts. At the end of the race I run out of gas right at the last turn, and 4 guys passed me. From P2 to P6. Anyway, I am checking if, by any chance I am doing something wrong. I am positive that I am not pressing the button twice.
