Complete Newbie: Can rusEFI do it?

Hello,
I wanted to make a electronic ignition controler for my Old Honda 2T. It has one Hall sensor and one magnet on flywheel:

Its positoned about 34deg BTDC. Can rusEFI calculate the ignition timing from that sensor? It would need to do something like this:

To get 11deg advance: Calculate RPM from amaunt of pulses in given time, get pulse from hall sensor (34deg BTDC), wait calculated time (33deg), give pulse to ignition coil.

I hope its understandable.

Also: Can that simple rusEFI run on stm32f411?

I understand the short answer is yes it can do it. I haven't seen a crank it can't decode yet. The question is more about does it currently do it. The software level of the rusEFI crank decoder is extremely flexible. Making the decoder is one level of development then updating config files fur tuner studio is another step. The harder part is the decoder. The software developers need detailed information about the crank. This often can be a detailed drawing showing the cranks pulses other times it's a recorded log file.
