You are OK and correct to be concerned what that does and how it works. The main point I want to make again is that you should NOT be messing with it if you aren't getting closed loop. You have no way to know where it will end up when and if you ever get it in to closed loop, and if it isn't in closed loop, nothing in changing.
I'll try to explain it again;
If you look down in the hole where the anti-tamper ball or plug was, you will see a hex shape, that accepts an allen wrench. The other guy seems to confirm it is a 3mm. What that is is sort of like an extension down into the airflow meter and it is spring loaded in the "up" position. You insert your allen and press down on it, the lower end then goes down and engages into an adjuster screw. Sometimes you need to fiddle with it a bit to get that lower part to engage into the actual adjuster down below.
The only way to know is by trying to see if the crack is messing anything up. If it is you can buy a new adjuster tower.
First thing I'd check in regard to the fixed operating mode (ie not going in to closed loop) is the overvoltage protection relay (check fuse).
