Hello, I'm new to the game and I play on an Xbox 360. This is my first post here, so "hello," as well. I searched for R&D on the entire forum and even though I see threads that contain that phrase, it wouldn't pull them for a search. I assume this question has been asked before I apologize. It seems that when I do an R&D session I'm doing it 2-3 times and then I don't necessarily get that upgrade after the race. I'm currently in Turkey and the only upgrade I've successfully gotten is the cruise throttle map setting. It's been telling me we're doing R&D for a new throttle map setting for like three races and even though I beat the requested time every time, it doesn't seem to be "taking" if you will. Are there some parameters that are required? I notice a "glitch" where if I load a tune or change my tune settings before accepting, the time is much easier to beat? Does this have a negative effect? If there is a thread were all of this has already been discussed I'd love to be pointed in the right direction. Thanks.
