Hey guys,

I'm interested in monitoring my instantaneous mpg, (largely because I want to run some controlled tests to determine the most efficient acceleration method).

MPGuino vs Scangauge

As I understand it the Scanguage is:
More expensive
Needs OBDII
Less Accurate

But the MPGuino is:
Harder to install
Not easily removable
Displays only one readout at a time


As such, I'm leaning toward the MPGuino, but being non-removable bothers me a little, and I'm worried I won't be able to install it correctly. So,

1. Does anyone have suggestions?

2. Has anyone put an MPGuino in a prizm before that could help me if I get stuck?
