new update! some low powered engines didnt work with the frankly jank way i did the idle throttle calculations. i realised there was a much simpler way to kickstart the AFR calculations so its now all good

i updated it again. turns out i forgot to switch two numbers and it was broken. should work now!

XD

updated! should work much better now!

im working on an update, it needs to be tuned for different engines weirdly. will keep you posted

does it work with supercharged engines?

Also, you use CSV logger? or collect experimental data by hands?

You can use loopback of manifold control for calculate flows/throttles relation. But need some sync for divide data from one time. When you calculate current relation (flow/throttle) you can directly use it in calculation instead PID.

AFR its not very effective spot for control. Better use stoichiometry (this value directly affect to efficiency/power), and its depended from temperature. check my controllers - pure math solution.
