For the auto lock i'm pretty sure if you cut the wire running to the ECU that controls the speed cut, then it'll disable the auto locking, and it's a cheap way to remove the speed cut. The downside to this is that the hicas light on the dash stays on, I just took the light out of mine, but come time for inspection, over here in Okinawa all of your check lights have to work, so i always have to hook everything back up. I'm not sure about the beeping, mine was stock turbo so it didn't have that, but it's probably controlled by the same wire
