Yes, of course, for years I did reverse engineering on italian ecus to understand behaviours on different engine condition, I was very fascinated on it and then a few years ago I decided to build one myself with bluepill stm32, even it is much more minimal than rusefi, it worked very well for small engine (1 coil and 1 inj) but I have suspended the project, my free time is less and less.
At the moment I have no active project, but maybe if I find time to study on rusEfi I could mount it on a turbo engine
