Fuel Smart as seen of "Gearz"

[One Acre Farm]

I am curious if anybody has installed the Fuel Smart computer that I recently saw on an episode of Gearz. If so, have you noticed the 15-22% mpg gains without loss of power? Any thoughts would be great!

There is no way to make the same engine produce the same power and yet decrease the fuel used via gas management. If you reduce the fuel, you are going to loose power. The computer may cut the flow for cruizing and then kick it back up for needed acceleration and do it better than the OEM computer but 22% better, I seriously doubt that unless it cuts the HP by the same amount.
You could put on a turbo or supercharger and reduce fuel requirements while increasing power but just managing the fuel delivery, very unlikely.

Gary, thats fine. Who needs 472HP or what ever most of these trucks produce in everyday driving? I would give up HP on my vehicles for increase in mileage as long as it was "tunable" on the fly or at least with engine off or something. When towing or driving on the interstate yea you may want 90% of your power or 100% but on a lazy drive on backroads to work why do you need your truck to pump out 410HP or whatever they do?

My 30yr old 1/2 ton 4x4 chevy with 175 hp from the factory when new will still accelerate as fast as you reasonably need and will still get me one **** of a speeding ticket on my way to work if i drive it like i wanna get a ticket. But for normal acceleration speed maintaing passing etc its got more than enough power.

While I'm not going to say it's impossible I will say that companies building cars and trucks spend millions trying to figure out how to get the best fuel economy while giving the maximum amount of power while giving you engine life longevity. I doubt that a small company could come up with a way that none of the large companies could.

Now one place that could offer fuel mileage gains is to control the throttle electronically. Since cars already have "fly by wire" when it comes to the throttle so it wouldn't be too hard to filter out bad habits like pressing harder on the gas than needed for short bursts. Or for that matter things like controlling the brakes when the throttle is being pressed. Basically you could press a button and the car could be programmed to run to optimize fuel economy, press it again and you're back to normal.

20% or more sounds like a stretch though.

Our 2008 Tahoe has factory cylinder deactivation system. When cruising on the freeway for example, the Tahoe will average up around 24 MPG with the system active. That is a 6 MPG or 25% improvement. The over-all MPG average of the vehicle seems to be unaffected since cylinder deactivation on time is minimal so I really question the pay-back time of this device considering unit cost plus installation.
