I've found it invaluable when setting up my fuel map to be able to "lock" the car to one specific load value via tweaked BWGDC table, then hold a specific rpm at WOT via left-foot brake.
Without booking expensive dyno time, this is the only way I can get sensible wideband readings in spool-up load areas.
All of my fuel map's "transitional" cells have been set this way. My RA will happily hold at (say) 3500rpm/160load, and I can get an accurate reading.
Now if my ECU decided to throttle me back, I'd be down to just one option for setting spool-up area mixtures... dyno time. Fortunately, my car allows it. Others aren't so lucky.
I know itzwolf wants this thing solved for the exact same reason as me - to check fuelling mixtures at specific map points, "steady state".

I could give two ****s about the bad reasons people "associate" with brake boosting. In my application like Rich's its valid and worthwhile.
Why don't you just go to the track instead of trying to impress people. There is no need to brake boosting during ordinary daily driving unless you are doing roll by races like Kracka said.

^You don't need to bash everyone talking about brake boosting, that doesn't do any good.
Also, its not that tough to text/type **** while sitting at a stoplight. I am not saying he wasn't being a tard doing it while driving, but he might not have been. Not worth it to make all these assumptions.
I have never brake boosted, but it doesn't mean others don't want to use it. I just downshift, works fine.
