1: Install latest firmware (1.61) and calibrate your throttle (VERY IMPORTANT) https://www.youtube.com/watch?v=jVI6fy5wzn0&ab_channel=Thrustmaster
2: Delete all A32NX mod that you currently have in your community folder. This includes the one inside the community folder, and the A32NX folder outside the community folder.
3: Start the sim, and delete the control profile you have previously for the TCA Throttle Quadrant. Let it reset to the default.
Reset the sensitivity curve by pressing the Reset button for all axis. And press OK. When you reopen the sensitivity curve, it should be perfectly linear in a straight line. The sim should prompt you to save this new sensitivity curve as a new profile. Save it.
4: Download and install the latest Custom A32NX mod into your community folder: https://flybywiresim-packages.nyc3.cdn.digitaloceanspaces.com/vmaster-cfbw/A32NX-master-cfbw.zip
5: Once you install this new custom mod into the Community Folder, run the sim once, and start a flight in any gate of your choosing with the modded A320.
Test your throttle, you should see the detents are not lining up properly. Exit the sim.
6: Go to your Packages Folder (https://github.com/flybywiresim/a32nx/tree/fbw/docs), and you should see the new A32NX folder created. Open it, and open the Work folder. You should see the ThrottleConfiguration.ini file.
Open the ThrottleConfiguration.ini file, and replace the contents with this:
Log = true
Enabled = true
ReverseOnAxis = true
DetentDeadZone = 2.0
DetentReverseFull = -1.00
DetentIdle = -0.50
DetentClimb = 0.00
DetentFlexMct = 0.50
DetentTakeOffGoAround = 1.00
7: Start the sim again, and your throttle controls should now be perfectly aligned for each detents and sensitivity correctly linear. and the Norm switch works, provided that you keep all the mappings back to the default post-patch.
Not my work!
