do passive modules still give their bonuses when the ship is not piloted?

there are some Passive ECCM Modules (Backup Array)… won’t they work even when you aren’t in the ship?

They will, but it looks like it is not enough.

well… the question wasn’t only about making ships unprobeable but thanks for the answer ^^

My post contains answer for all points of your question, just in different order. Point about MWD is the first one – inactive MWD does not give any penalty to signature.

Just need someone to do at least some testing I commented in RedMage’s answer, I won’t be able to do that in near future since my client died for some strange reason and I can’t get another one for now…

Will turn off or will go offline, that’s the question.

are you saying all modules that require skills will go offline? cause i don’t think there are that many modules that don’t require any skills ^^; please word your answer better?

that is exactly what i was trying to say. All those mods have an offline effect. Test it… fit a raven w/ some extenders, undock, eject, see how much dmg it takes to take the shields off. It’s the only way i can think of to test it.

You may fit some passive shield hardeners on it(say, EM) and shoot one time with something EMish, repeat it again without hardeners and compare damage. Or load some signature increasing ammo in its launchers and compare locking times with it and without it. And there is still a question, will active modules stop their cycle once you eject or they will finish the cycle. MWD and locking time compasion will do the work. And you don’t need to eject for one part of any of these tests actually. Unfortunately, I can not do any of these tests…

And if really anything requiring skills will turn off, there is one more way to test it. Civilian Expanded Cargohold doesn’t seem to require any skills and gives -30% to structure, so full rack of these and some shooting will show you their status. Try not to kill your Raven though, 5 of them drops structure ehp to 1100ish number.
