Thanks for responding. Can you be more specific? What feedback does it give that you are monitoring and which is helping with FE?

I don't like the instantaneous mpg meter on the NAH. The bar graph is not very accurate, IMHO. But, not sure a digital readout would buy me much more. Do you use the throttle reading to determine driving habits?

Also, is the OBDI connector right under the steering wheel?
Do you have a pic you can post of what it looks like mounted?

Thanks!
