Simple AFR Controller

They finally fixed the issue in today's update

Fair enough (gotta love stormworks devs)

Yes, the devs changed a core mechanic... again. Sorry, i don't play this game anymore. I am fed up having to re-engineer everything over and over again.

All my engines that I run supercharged, that use this design somehow run much much worse than 2 weeks ago, where the non-afr controlled engines are better than this

Saw this on a tutorial came straight on here to look for it as im just getting into building my own engines atm. Inspired as im trying to make a plane and the regular engine is just too wide so im making and inline. Havnt tried this yet but thanks for the effort, i already know its not easy as i messed aroun for 3 hours with air and fuel levers just to get my engine to kick up without stalling.

I must thank you for this controller and the hard work you've putted into it.
I'll make sure to credit you on my ECU and if I ever post something in the workshop using parts of
your controller

You can leave the stoichiometric input empty. The input regulates how lean or how fat the air to fuel ratio is. Most people use a constant with 0.2 on this input, because the engine will run most fuel efficient and therefore the coolest.

Important is to set the number somewhere between -1 and 1 (excluding -1 and 1).

You can also test which stoichiometric works best for your engine with a throttle lever on this input

Where do I attach the stoichiometric input?

I don't know why but I got a zero air-to-fuel ratio when using this????? How to solve?

Awesome, thanks for the clarification.
