I'd be glad to help you using https://ossia.io for that task : it's a DAW which also supports various non-audio / MIDI inputs, for instance you can directly read / write data from a serial port, and have parts of the score that trigger depending on external events. It already runs on raspberry pi too :)
From a quick Google, I found out that engine sound simulators are actually a thing and there apparently is that us open source.
