One of my long term aims is to produce an engine data logging system.
I am at the early learning stages at the moment.

I thought by reading this list I would pick up some ideas.

So I would measure the same things as EFI systems, only log the results
instead of using it to do EFI. I am thinking of using an accelerometer
as well.

Another interest is to add to the above system a control for nitrous 
oxide injection. 

Not quite the normal EFI, but EFI none the less.
