BTW how did you mount the EDGE, and does it give you miles left till empty?
I removed the ashtray from the dash, removed the insert from the ashtray, and drilled a hole up through the bottom. I then ran the OBD cable from the port up through the dash and into the bottom of the ashtray. Plug the EDGE in, snap it into the ashtray, and away you go. There is no mounting hardware or adhesives necessary to keep the tuner in place. Its a very snug fit so it stays in place on its own.
This way, if I want to impress my passengers withouth them knowing I have a tuner, I just close the ashtray and they never know it's there. On the other hand, if I want to figure out how my gas mileage is doing, I just pop open the ashtray and everything is right there in front of me. It also helps for servicing so my dealer won't ask any questions.
I don't think it displays miles left till empty, but I'm still learning all of it's features.
