Hi,
I've got a T300RS which is basically the same wheel as the TMX:
- steering lock: you should set it up to default settings in the TM control panel (should default to 900°). Then in AMS, you should select within the controller option page: "enable custom steering range" --> NO. The game will automatically adapt the wheel angle range based on the car you're driving (modern F1: 270°, road Camaro: 900°).
- beware, on exiting AMS, your wheel steering lock range will stay the same steering lock value that you had in the last car you drove in AMS. If you drove a F1 with 270° wheel rotation in AMS and you move to Assetto Corsa, your wheel angle range will be limited to 270° in AC. This is a "bug" which has never been solved in AMS. You have to go to your TM control panel and set it back to 900° (or any value you like).
- reversing FFB: my understanding is that with Logitech wheels you have to use a negative "Force Feedback Strength" value. Like -80. With Thrustmaster wheels, it must be set to a positive value. Just move the cursor to +80 and you're set!
Here are my settings (I set those up in 2017 or 2018. Never had to tweak it after that. That's AMS1 magic for you!

(wheel range changes automatically. Last car I drove had a default 630° range. Cannot remember which one it was)
