I'm having a close look at this at the moment and intend using
the same CPU as I have in mind for a relatively simple EFI ECU.

Essentially I am setting up an auxilliary dash board on top of my
current dashboard with some logging capability, for a turbo some
of the things I want to observe are AFR and differential fuel
pressure - as I would like to increase boost and injector
sizing. One display parameter is a large linear graph of
injector duty cycle, fuel flow rate (summ inj DC), AFR, MAF
and have these displayed simultaneiously with selectable
scaling so I can pin down relationships visually and more
or less directly whilst driving and not have to shift my
eyes to a laptop. ie. Neuro-kinesthetically whilst driving
so I can observe the effect during the same period I feel it !

Well, <cough> thats my aim <sigh>

But still want some cal graphs for MAFs - anybody ?
