better MPG. Of course, it's not as much fun that way.

They had that stuff back in the fifties but it doesn't take an Einstein to know that you can't step on the gas too much. Reminds me of going to a casino and leaving some money in the car.............just don't blow it!

I had one when I first got my Ex. It didn't work properly with the 6.0.
I worked with their tech folks and eventually sold it to a friend and
bought the SGII. I have subsequently gotten email from Ultra-gauge
stating they think they fixed the problem - but I didn't have it anymore to
try it out.
Plus, it doesn't have the "X gage" feature to add new PIDS to monitor.
It's display was VERY nice though -for the gassers it's a good deal IMO.

The main reason why I want one is to figure out which highway speed yields the best fuel economy. The ability to read codes is a plus, not to mention the ability to see readings from all the other sensors that our Excursions have...instead of the dummy gauges.

One thing to remember - the max load and capacity of a tire is at the max air pressure the tire can support. If you are towing a heavy load then you need to know what your tongue weight is along with the weight on the rear axle. The specs on the door sticker are a good compromise for ride and handling but you will need higher pressure when towing. When you have less air in the tire it means you will have higher rolling resistance which can build up more heat in the tire than desired and lower your mileage.

I never said I needed it, but i do think it's a useful tool. You obviously would have no use for it because you already know all about the foot going down mileage thing.........
But thanks for contributing something valuable to the conversation!
