CSL DD steering rotation settings?

Hi,

Just got this game and have a CSL DD steering wheel. Curious how to best set up everything in terms of steering rotation. Having played the truck simulators, I thought vehicles didn't go past 900 or 1080 degrees, so I set it to 1080, and was confused by the bus' awful steering radius. I later realised the bus actually steers 1800 degrees!

Do I just set it to 1800 degrees in FanaLab or whatever and the game and be done with it? Is there no way to have it automatically figure out the limit somehow, while still matching rotation with the in game animation? I actually wouldn't mind just using 900 as the limit, and I understand the Disabled if needed setting should do that, but not while retaining 1:1 animation.
