PnzrMods Engine Cooldown Tweak
This mod does one simple thing: cuts the time between Launches due to engine cooldowns in half. Even at a 51% launch quality, engines were taking over 3 days to cool down, which is nuts! Now all cooldowns are half as long when this mod is enabled.
Probably not compatible with any other engine cooldown mods.
I'm open to questions, concerns, feedback and ideas for how to make this mod better, please leave comments below!
