I always liked the idea of a 5 or 6 inch diameter gauge on the rear firewall of a VW Beetle. That would keep the vacuum line short and it would be readable in reverse in the rear view mirror.

The XFi has an Eco-light that comes on to prompt you to short-shift the gears. I don't know the logic of it, it certainly doesn't tell you when to downshift.
