Hi, I'm not sure, if it can really be called "bug". But if on you have "throttle cut" set "on" and "throttle blip" off (for example on STCC servers it's forced set with FXO), so you manually press the throttle in downshift, LFS cut the throttle, so the blip is not correct and sometimes, the wheels get locked. It's also much slower than if it's done correct (well, it's fastest if done by lfs /TC=on, TB=off/, but it's not so funny). The help is called "throttle cut on upshift" so I guess, it should not cut on downshift. Maybe I'm wrong Just try it yourselves - set TC=on, TB=on, then go on straight and downshift with full throttle. LFS release the throttle just a bit. But if you do the same with TC=on and TB=off, LFS fully release the throttle.

You are right! 'Throttle cut on upshift' cuts throttle on downshift too.

This is interesting. I've never really noticed it, but I've been having big troubles with braking in the silver servers of STCC. I guess this could be it. I assumed I was doing something wrong since I've never raced much with the XRT or RB4. I've been trying to figure out what was going on with my poor braking in those cars the last few night. I blip manually and it seemed like my timing on blipping on downshifting was way off. This must be the reason and I just never put it together with the throttle cut option and figured it out.

If this is definitely the case, then it is a serious issue since the throttle cut is being forced on STCC (which I disagree with). So, it turns a "get rid of a non-clutch/shifter user advantage" rule with STCC into a huge disadvantage for the non-clutch/shifter user.
