I think you missunderstood his complain. Everything works as it is planned to work... If i remember his complain correct - it was for RSB LSB buttons that are market on the rim, but not working, something like this. Everything that you have on TM wheel - you have it on Fanatec wheel and much much more
Well and what about the above mentioned bug, that the pedals are not recognized separately? I mean that either they are on the same 'button' or that you are forced to use automatic? That would be a no go for me, as I always drive without assists.
If the Xbox Hub, even if it's quite expensive, would resolve this issue, than I would also purchase that one, to be on the safe side.
They are on the same button. You aren't "forced" to use automatic. I will explain in more detail below. It's worth understanding the Xbox limitations of the CSL Elite PS4 before you purchase one of these wheels, especially if you plan to use it primarily on Xbox.
Here are the main problems with CSL Elite PS4 on Xbox games:
1. The LSB/RSB buttons on the wheel do not match what is input to the Xbox games themselves. Using the P1 rim or the McLaren rim as examples, both rims ship with "LSB/RSB" buttons on them. The problem is these buttons do not register that way in Xbox games. The buttons on the wheel do register, however, they register as LB/RB. That is a big problem because your paddle shifters are also registered to LB/RB. In other words, it renders LSB/RSB buttons useless unless you plan not to use paddle shifters and you drive with automatic transmission. On PS4/PC, you can map all 4 buttons as separate inputs. Simply put, while you are not forced to use automatic transmission on Xbox games, you can't use the LSB/RSB buttons unless you use automatic transmission (which then frees up the RB/LB buttons.....which are actually the LSB/RSB buttons on the wheel itself). I know, it's confusing!
2. The accelerator/brake/clutch pedals are not input as separate inputs as they are on PC/PS4. This is a separate problem, but has similar effects as the first problem in that it limits how many buttons you can actually use in Xbox games. Using the CSL Elite PS4 in Xbox mode, the RT/LT buttons are mapped directly to Accelerator and Brake in all Xbox games. They are not separate inputs. Again, similar to point 1, you are now unable to use or map any functions to the RT/LT buttons that are on the McLaren or P1 rims. For example, as soon as you try to map RT in any Xbox game....you will see that it moves the accelerator function to the new button and leaves the accelerator pedal itself unmapped.
A simple way of thinking about this is that, in Xbox mode, the wheel limits access to the same set of buttons that an Xbox One controller has. This type of limitation doesn't exist on PS4. On PS4, you have access to the paddle shifters and pedals all as separate inputs (5 additional buttons). Therein lies the problem with the Xbox compatibility.
Unfortunately, in my case, that problem matters because I tend to race with manual transmission and I need all the face buttons available for things like DRS, pit limiter, View, Camera change, KERS, etc. The wheel is still usable on Xbox, which I am glad for, but the limitations can be frustrating.
I say these things not to discourage you from buying the wheel. It's a great product. I love my CSL Elite PS4, but I mainly race on PS4 and only use the Xbox compatibility here or there so the limitations don’t bother me too much. If it were me, I wouldn't buy this wheel if your primary racing will be done on Xbox. I would step it up and buy the ClubSport 2.5 or the Hub, as you mentioned. I had the 2.5 before and I do not recall having any of these issues. As far as I can tell, it seems these limitations are unique to the CSL Elite PS4 when used on Xbox.
Hope this helps. Hit me up if you have any questions.
EDIT: One final caveat. I also use ClubSport Inverted Pedals, Fanatec shifter, and the Fanatec handbrake in my set up. I have no idea if that matters, or if that has any impact on this functionality. It shouldn't as all Fanatec products claim to be compatible with each other, but it's worth mentioning. Fanatec support said it didn't matter, but who knows. As I mentioned, everything works absolutely perfectly with PS4. Perhaps someone here with the CSL Elite pedals has had a different Xbox experience?
