Mfd works okay for me Frex. I’ve set it to my d-wheel joggle on the wheel for easier manoeuvre about the menu.
Yes, that's exactly what I've done. Like I said, all worked fine in a practice race, but not last night in the online race. I could navigate around the MFD as normal, but pressing the button to confirm choices just locked up the screen. I will have another look at it, probably something wrong with my button mappings that only shows up in multiplayer.
I'm also aware you have to be in first gear for the limiter to work. My main issue with it now is ensuring I am down to 50kph before engaging it, as that feels incredibly slow, and if you're not down to that speed before the pit-entry line you get a penalty whether it's engaged or not - could that be the problem?
