It works. I am in GT5 now at Monaco with an F2007. In cockpit mode you can watch the in game steering wheel lock and the front tires hit lock.
I have power steering enabled in the global wheel settings.
Upon Initiating the "1+2+T" setting, it takes, from G27 wheel center (joggled a little to get in game wheel centered) about 70-80 degrees of movement to get the in game wheel to it's lock and another 30-40 degrees for the front tires to hit lock. The G27 steering gets seriously stiff when the tires hit lock.
"1+2+S" From G27 and in game wheel center - in game wheel stops at G27 wheel approximately 110-120 degrees of movement, tires lock at G27 200-210 degrees of rotation.
"1+2+O" From G27 and in game wheel center - in game wheel stops at G27 wheel approximately 170-180 degrees of movement, tires lock at G27 300-320 degrees of rotation.
"1+2+x" From G27 and in game wheel center - in game wheel stops at G27 wheel approximately 220-240 degrees of movement, tires lock at G27 420-440 degrees of rotation.
I used no instruments to measure these values, just eyeball guesstimations.
And while you can move the wheel past it's set "lock" position doing so will not gain you more steering angle in game and it will be much harder on your wrists to work the wheel past lock.
It seemed to take at least 2 tries at the button combo for the setting to stick and sometimes the in game wheel would jump slightly off center when it did stick.
Big thank you to Odefinn and piscota for posting this up. 👍
Will hit one of the time trials at some point this weekend with a reduced setting to see if it changes the report there.
I have no other racing games to try this on but I suspect it's a button combo programmed into the G27 by Logitech and not software dependent. I could be mistaken.
- Lock setting appears to reset after PS3 reboot.
- Lock setting retained after exiting and re-entering track.
- Lock setting retained after room exit and rejoin
- Lock setting resets after game exit & restart
With the above list in mind perhaps my first impression was mistaken and it is software dependent.
