I intend to write it up soon - and yes, very rewarding. Already seen another 10 to 20% or so mpg increase in the few days since I've had instrumentation; though the proof will be at the next fillup of course.
Naturally there are a few small issues; I think my pressure logging is still not quite right; a cross-check with a voltmeter will shed some light on that. It's fascinating to see when the engine uses high injection pressures and when it backs off.
I have also noticed that the guino reckons coasting in-gear uses a lot more fuel than out of gear. That could be down to the code struggling to pick up on some very short injection pulses, I don't know.
