Digitise an older engine - ESP32

[Techstyle]

Hi, I’ve just added fuel consumption (predicted based on RPM) so if that’s works I’ll share all the code either on GitHub or on here. Plan to test that this next week.

I have just used the examples and stuck it all together but happy to share.

this might be a good addition to the SignalK derived data plugin.  There is a current calculation for fuel economy using fuel rate and Speed over ground.  RPM would be better, I think. - https://github.com/SignalK/signalk-derived-data 

BTW - I would have guessed at South Wirral/Chester way.  I used to work in Runcorn and live in Elton (CH2)
