VX lean burn monitor - enhanced how to desired

[McPatrick]

I know all about how much time babies/kids can take up, so you probably find yourself without much time on your hand, but do I dare ask if you have a new guestimate as to when you'd have your kit ready (which hopefully would come with a fairly idiot-proof how-to)?

And in what way do you expect would the info that this indicator gives you change your driving habits when it comes down to religiously obeying the shift indicator already present on the dashboard?

Should I think of a situation for instance when you're already in 5th gear, going up a hill and with the new indicator finding out that you can still drive in lean burn going 55 mph but not doing 60 mph? Or what other situations would the extra information be helpful for?
