LOL yah I messed up; typical user error problem. I was looking around and found the text that said "make sure simhub is closed"
On another note, i'm noticing that my LED rev lights are not matching that of the in game dash rev counter. Seems like my LED lights are hitting the top sooner than the in game indicator this is especially noticeable in 5th gear on the 911R
It depends of the game, however the leds are using the RPM reported by the game (it can depends of the settings too) but my default settings uses the maxrpm reported by the game, while game dash have adaptions and some various addicionnal. So I can't assure it's a perfect match compared to the game. (some in game car dash will reach the last led earlier, some later, some will not have a linear progression like some f1). But at least it should be conform to the data the game gives.
What game and dash are you using ? Some dash moreover on the nextion templates from BuToNz have been made to match the in game dash (pcars1 taken as reference) , He has taken a massive amount of time to match it, but it will not adapt itself to another car/game
