Any Decent Converters for Unsupported Steering Wheels? Ideally it would work on both Xbox One and PS4. The wheel I have in question is a Logitech G27. All the converters I’ve seen have either massive deadzones and/or input lag.
Have you looked at the ‘Titan One’? I have one but haven’t set it up yet. There is also ‘ChronosMax’ but I think the TitanOne is a better/newer device.
Those two devices mentioned above are gimicks, they emulate a controller so your input is very skewed, and no proper force feedback
The one you want to look into is called gimX, it’s an open source DIY project that has proper support for Logitech on the ps4, and I believe they are working on emulating the g920 on the xbox one which means you’ll be able to use older logitech wheels and fanatec wheels too (fanatec wheels emulate a g25 in ps3 mode)
CronusMAX is light years ahead of TitanOne - I think you’re responding to their internal marketing hype 
Cronus was even used in this weekends Call of Duty XP 2016 World Championships by every team on every controller.
To Blue028, CronusMAX has come on leaps and bounds with regards to racing Wheels since you posted this.
