geez...you got a Snap-On scanner?  rich guy....

OBDII hm...mixed feelings...with OBDI I can retreive the codes without any tool...but not with OBDII.  Lucky my friends work in shops so I can borrow their scanner if I need...heehee

Back to the topic...I don't know how useful it is to know about those inputs of car and how many mpg I'm getting (I can find out every time I fill up).  Given that the car is maintained properly, I would never care to see those info.  The only good thing about it is that it gives your the trouble code.

Btw, there are many other better options...pay a bit more for better ones la
