The "engine_type" variable did the trick, thanks I've read the readme file that's delivered with your plugin, maybe you should update it There was no mention of an engine_type there But maybe I should've looked into the aurora.cfg file, I would have seen it there ^^ I'm not new to cfg editing, I'm just not used to it anymore The EC values were already implemented to your specifications, so no problems there. Btw, it would be really neat to control the impulse drive with keyboard inputs, e.g. numpad keys (8, 2 forward, reverse, 4, 6 port and starboard, 5 all stop and so on). Now I just have to figure out how to blast stuff with photons and phasers
