Most of them are unreliable and seem to fire in random directions. The direction seems to be related to how you approach the SCE (from what side) and I have not been able to figure out a reliable pattern. On the other side, there are some of them that always fire in the same direction regardless the circumstances (eg. where you place them, how you approach them, etc).

I have not yet played with the parameters and I think the answer lies somewhere within the memory. There should be a memory value which tells how a SCE behaves, but I have not been able to locate it. Even should you somehow locate it theres no telling whether you can directly edit it from JCS. Let me know if you find out anything.
