I received my parts last week and fitted the TQS mod last night - with TUSBA - and I couldn't be happier with the results.
Installation is very simple, just watch the TQS video posted earlier in this thread for what you need to do.
After installation I ran Realsimulator calibration to set Min, Max, Idle and Aft positions thereafter, checking in game, I am delighted with the response from my TQS - no more dead spaces in the TQS travel, it's now extremely responsive to physical input.
This mod has breathed new life into my TQS, I recently installed a new Z axis pot from TM and still had dead space issues now my TQS is finally working the way it should have from the beginning.
If you have any dead space issues with your cougar throttle axis then this mod is what you need, it's inexpensive and just works.
Brilliant, can't recommend it enough.
