It seems to me, the Hardware one not match my TAC throttle.
As this throttle hardware have physical reverser range on the same axies and I defind them with FSUIPC, I feel that the CS's panel use full range for the "Hardware" display rather than only forward range. When I have my actual N1 on like 60%, and condition for this panel to show, I have to move throttle to like 40% N1 before it can catch and be moved again, thus moves software throttle way low to 40% and lost power.
Hope you can figer it out, or at least option for disable such function if it doesn't work for someone. (I'm OK without it in like CS757 or other Boeing add-ons.)
