Testing with it set to cap at rank 2 / 3500, there's no way in the hangar (even while logged into a lower-rank server) to see what parts require what rank once you're ranked up enough to use them, which makes it a bit frustrating to try to make anything lower than rank 3 or 4 without doing a whole lot of guessing, and the 'free budget' in the editor is wrong (it shows it out of $6000 instead of (for instance) $3500).
The other bug is that trying to join while you have a too-high-rank-or-cost ship selected doesn't let you join and doesn't explain why. (It should probably either explain or change your ship)
That aim-bot isn't perfect, btw. And there are two, one that shows you where to point (the robo-sight), and one that does the aiming for you (the ballistic cpu), but for the second one you still have to point it in the general area of the target and wait for the turret to face them before you can fire. The second one seems to have issues with firing at anyone while flying at max speed (or possibly just high speed in general, and can't hit anything while turning either.
The tradeoff for the ballistic CPU is that it is horrifically expensive and you can't have as much of other stuff (like more guns, ammo, thrusters, armor, etc), of course.
I'm not sure what the purpose of the point defense CPU is. I've had it flip out and kill people before, but I wasn't able to get it to do it consistently, or to get it to shoot at "munitions in flight" (except missiles, and then only when it was already too late).
Edit: *turns off the cap, turns on 0 air pressure instead to see how that screws up all my ships

Edit #2: Jet engines are super effective (I was expecting them to not work at all) - I just went plaid with a single jet engine. Fins and rudders don't work, probably airbrakes too. Also, the bots were all getting killed by air defenses.
30000% air pressure: The carriers are spinning violently, and eventually spontaneously exploding. The ships are spinning violently too, none of the bots can move. (Wow. I just went plaid without ever pressing a button.)
Turning off carriers patrol makes them stop spinning, but everything still spontaneously explodes after a couple seconds.
Anything above 10000% seems to be broken (or unsupported, one or the other).
(It turns out the config file's air pressure is in a 0-1 rather than 0-100 form.)
200% mostly makes things a bit slower. Maybe 2/3 as fast? Might depend on engines.
1000% is playable but slow without special measures in ship design. It's interesting, although it turns bots into sitting ducks and probably makes aiming easy even without the auto-aim modules.
