After my debacle of putting along @50mph for miles and watching the OBC mileage not change to blasting along @90mph for about an hour and watching my OBC mileage RISE!!! I decided I need something better to monitor my fuel use.
The E is available here for about $130. The II will suck $240 from my wallet!!!
I see though the E can monitor everything the II can with the benefit of a real time fuel use graph. Great if it's accurate.
I think most people have the II but was that because the E wasn't available when you bought?
If you had to do it again which model would you go for?
