Don't you hate it when you have too much fuel/oxidizer laying around? Which you could change the mixture ratio that your engines use (like the J-2 did in real life)? Want no more. Introducing: EMRController
With this mod, you can configure your engines to use different oxidizer/fuel mixtures, and have the ISP and thrust adjust accordingly. You can even set up your engine to run in "Closed Loop" mode, emptying your tanks at the end of a burn.
This mod does not contain any configurations, but if you use Realism Overhaul, you'll see that the J-2 does have configurations that work with this mod.
