Fuel Mileage Thread!

Hey guys, Jackfish again. So, i was watching Gearz and Stacey David was talking about this fuel saving device called fuel smart Now i did some look up on it. It lead me to this website, http://www.fuelsavingguys.net/Home.aspx
Im not sure how to think about this. It says you install it between the PCM and the injectors, it acts as a variable cylinder displacement system, and offers 15-20% fuel savings. NOW! Is something like this plausible in a car like ours? Or would this device even work? Any input is fantastic and appreciated.

It's pretty interesting, I'm not sure if the ECU would like it very much though. Considering I drive over a 1000km (600 miles) a week this would probably pay for itself in a few months for me. However, the risk of engine and emission system damage is still there. Plus, it sounds you'd be getting some drive ability issues especially at idle.

You're going to get a lot of responses from people who have never even tried this device saying "it doesn't work". I honestly don't think it'll work but the only way to KNOW is to try it. You'll be sacrificing money if it doesn't work, though. My theory on things like this is: if this really works, more people would know about it.

It's worth a try I guess, but you have to think well... Why wouldn't Chrysler/Dodge do this themselves? But I do not specifically know what this does as well as how it would help. I mean I guess it's worth a try if you want to do it. Keep us updated if you do, but this could be just another "Programmer chip scam"

Now sorry I misread what it does. Sounds plausible, but really don't know how are actual ecu will react to it. Always need to start somewhere I suppose haha

Is it trying to replicate some of the newer engines that cut out cylinders based on power demand? If so, I would think it would cause the ECM of our cars to throw codes for cylinder missfires considering the ECM has no programming for that kind of feature.

Same reason they don't put iridium spark plugs, cold air intake kits, etc. Because it costs more.

That's most likely what it is.

I've recently started watching some of these modding shows on the Speed channel (I started to say "...on Speed", but figured that might be taken the wrong way). Some of those guys say things that indicate they are missing some important pieces of information or don't have a problem misleading gullible watchers to sell a product. I don't recall if it was that same guy or a different show similar to his, but the other day, they were hawking a product and talking about how important it was to clean and paint up the battery tray - that if you didn't, "it could lead to problems inside the engine" - their words, not mine.

"Since the throttle valve is nearly closed, engine has to draw air and work inefficiently causing a 'pumping loss' ". That would still be the case for closed throttle (deceleration) conditions since this device dodes nothing to open the valves of the cylinders that are disabled. But for low speed coasting and light acceleration, during which the throttle would be open some, the PCM would put more fuel to the cylinders that were not shut off, and to get the same power for maintaining speed or lightly accelerating, the pedal would have to be pushed a little more to provide them the air for stochiometric operation, so then the pumping loss would be decreased.

My guess is that there will be some fuel mileage improvement, but I would take any stated or implied numbers (i.e., comparing to production vehicles where cutting fuel injectors off is only part of what's done) for the improvement with a grain of salt.

I don't believe the bullet that says "Reduce wear and tear on your engine". That's just marketing hype for the gullible.
