it is materially impossible for a device connected to the OBD2 port to control fuelling and other parameters (eg. turbo pressure) in real time.

[@revealingfacts4all]

I legitimately work on this stuff. Everything you said is practically correct but to expand on what you said, it's impossible to purchase anything that plugs into a CAN bus and auto learns like it claims. Each automobile manufacturer has individual ECUs that are specific to them, the car, and a number of other variables that are simply not released to anyone outside the company. Folks who reverse engineer an ECU are basically reverse engineering something called XCP. XCP is, essentially, a memory map inside the ECU where variables are stored and no two ECUs have the same memory map. There is no industry standard that states, for example, all auto manufacturers have to use some standard memory map. Hope this helps to squash the bullshit. Keep calling them out Dave!

[@DFX2KX]

I was about to say "Wait, don't you have to replace the ECU with a programmable one? or at least remap the stock one? And can't leaning out the mixture damage the engine without other adjustments to accommodate??"

[@Plexico41522]

@@DFX2KX Leaning out a fuel mixture is pretty pointless and can be damaging. additional fuel economy by programming is usually achieved by cutting back on emission settings. limiting throttle plate action (example if you limit the throttle plate of a car to say 85% itll have reduced power but likely save you a bit of fuel. or limit it based on rpm say under 3000 rpm it only ever opens to 50%(most manufacturer does this to some extent)) another way is to adjust shift points in a automatic transmission because basically the more time spent in higher gears the less fuel the car will use. but also the less responsive it will be. pretty much all things that you can control while driving the car if you think about how far your pushing the gas peddle. now real reasons to reprogram a car would be if you added major performance parts like changing the cam or adding a super or turbo charger, you can disable some emissions things to gain more power. (which should only be done if its legal where you live) a big one for dodge is disabling the mds which in my opinion only really helps if your doing a lot of idling and disabling the limits on low rpm throttle action. this while it doesn't actually add any top end power. makes a car a lot more responsive.

These are my fave type of videos. Most people know these types of devices are bullshit but seeing you do the tear down and showing how they do or don’t work is fascinating to say the least. Great consumer advice too, because I know people silly enough to fall for it and hand their hard earned over.

FACTS

[@rswow]

O come on. Have some heart. I mean, how can an invention invented at it seems the same time by two DIFFERENT people ("James Dawson" as per 1st video, "Christian" as per 2nd video, with different credentials ("engineering student" vs "ex-programmer" who "worked in the ecology department ") and oil-company fiascos ("an oil company approached offering millions for the rights...big oil companies are fighting to sue it into oblivion" vs. no such offer + "sued by two big oil companies") and that ended up with the exact name and design and color NOT be magical? I mean, think of the odds of two inventing the same thing! Believe in magic. It's got to work man. Buy it! My guess is it got produced in parallel universes by 2 different youths; what's your guess? Transcripts & video links to follow.

[@Supashada]

im confused because i plugged one of these into my 1996 chevy express van and it increased the time the fuel lasted for a good bit, almost double.. I dont know, maybe these actually work on really older cars or something? because ive actually tested it, driving to a destination a hour away and back, and without the eco thing i lost more fuel.. idk how else id have gained the fuel advantage unless these work in some capacity.. unless someone can explain why my fuel lasts longer with this in my van.. also tried out with my 2009 chevy silverado and the same thing.. the fuel increased.. but maybe its messing up my car or something?

[@DadSkool]

you got it all wrong Dave, It actually works by using the LED's to remind you to drive more efficiently

[@vincentrobinette1507]

Where's the Federal Trade Commission when we need them?

[@paulmunro3050]

I bought one, didn't even have to plug it in and I now get 500mpg! 10/10 would recommend!

In the past their was a thing called false advertising and you sue the shit out of these companies

[@Goldstreamplacer]

And you can bet if your car is under warranty, it will be voided if the dealer sees that thing lol.

[@burnerjack01]

The short answer: "ALL 'fuel savers' are bullshit. If that were not the case, car manufacturers would include them or be mandated to do so." If it sounds too good to be true...

[@burnerjack01]

@Panthera The automotive industry is insanely competitive. The various departments, engineering, styling, etc. are under intense pressure to gain a market advantage. Mileage is *SUPER* important to consumers, investors and governments alike. They would jump at the chance to be able to brag about a 4mpg advantage over the competition. Diptane? what's that cost? What does it do to O rings and seals? What by-products of combustion does it produce? Humbug. You can run a car off of water too, if you add prussic acid. A really, really bad idea, by the way.

[@demariojason]

Well I'm telling you guys right now, mine worked like a charm. Saved me about 10mpg, on a fill up; it was great 👍. I drive a Camry and I drove it around the country on about 2 1/2 tanks & then things faded out & I woke up to realize that I over slept & it was time to go to work.

[@stewartsaunders5107]

Thank you. Just, thank you for reassuring me that I’m a gullible donut when it comes to saving a few quid. I nearly bought this devise then thought I’d check it out. Thank you! How is this aloud to be sold on Amazon? How can every review on Google give it the thumbs-up? Please…I really don’t need an answer. I know. I’m really quite new and very naive to the internet.

Many thanks. My dad brought this product to my attention so I appreciate your work in debunking it so I can tell him. Edit - Subscribed!

[@samgab]

Is the micro an LED controller of some sort?

[@ollieb9875]

I was kind of thinking it looks like a CD4017, something like that which could, with a slow timer give a little display.. I half expected to see a little 555 timer there..If its reset pin was tied to the actual reset button, that would work too!

[@bigclivedotcom]

It'll be the cheapest microcontroller they could get to jiggle the LEDs.

Thank you for the video, was tempted to get one , but after this , I'm going to put £12 of petrol in my car , instead of buying a Turd With a flashing light on it . Hi from UK .

[@markcobb4693]

I put 3 of these on 3 different cars, did nothing ! My grand caravan got a brake and engine light saying replace gas cap did that now it says purge valve and brake light, got all new brakes and wheel bearings and sensors still have light. I wonder if this thing did some damage.

[@metoo072954]

Thank You for us who don't know how to test things like you do!!!!! and save us from awful scams!

[@yshouldicar3]

Big Clive tore down and reverse engineered an older version ages ago but also did tore down a newer version recently.

[@szankony6276]

But there is nothing to reverse engineering - just throw it away into a trash ;)

[@EEVblog]

He missed that there was actually no connection to any of the CAN or other lines due to the silkscreen.

[@yshouldicar3]

@@EEVblog Fair. To be honest I haven't actually watched more than a minute of you this video since I had already seen Clive's.

[@Wilson84KS]

@Szan Kony AeroBike_EU Team The smartest comment I found here, people are retarded anyways, that ones that buy that and believe it works have no idea about any kind of technology they use, just because they have no interest so they also don't watch any video of EEVblog or bigclit or how that alcohol loving guys channel is called. But in the end the people are always the scammers themselves, driving some hundret kilos of useless plastics, scrap metal and atleast four empty seats around for some hundret meters and then spend money on bullshit to save gas, some of them even just to show that scam is scam, and not to forget about the gym, live like pigs and complain about the consquences, truly advanced society.

[@AKADriver]

Fuel saver scams are as old as cars. I remember seeing ads for mail-order plans for a "100mpg water carburetor" and other secrets that "big oil doesn't want you to see" in the back of magazines as a kid. There's no way a simple universal plug-in device could change engine parameters. A custom firmware tune can do it, like you said, but the manufacturers constantly change the factory-installed firmware, so universal devices are categorically impossible.

[@hansnovel965]

Well my friend, I have 2 older ones with re-set button on outisde, THEY WORK!!! consider myself well experienced, 50 years mechanical, auto sales ect... own a 2003 Yukon Denali... I measure my gas consumption as you should: fill tank, drive milage, fill again on same gas station,, gives you e x a c t milage! My yukon used for several years 30 liters to 35 liters per 100 km!!!! Had my Eco installed but not re-set for years, nothing changed, then I re-set it and what do you know? I now uses exactly 21 liter per 100km..checked it many times, still 21liters, a big difference!!! So, purchased 2 new ones like you show, they dont work as you said... the old one DOES WORK!!!!

[@bwmitchem]

Hey Dave. I opened one and it only connected to the power and ground pins. It had 3 leds. Two that were only hooked to power through current limit resistors and the 3rd that went to a two transistor monostable blinker circuit. The reset button just stopped the monostable for a second. The markings on the side of the device was "Ultra Fuel Saver"

[@wollywotsit]

Think big Clive covered this

[@rimmersbryggeri]

HE did it years ago.,

[@theukuleleist]

@@rimmersbryggeri he also did a recent video on them to see the difference between the older ones and the new ones

yeah but Clive didn't do a short drive around Sydney

[@martinj9647]

Far better too

I didn't know about that, but yes he did. But it seems he didn't notice that there was actually no connection to any of the CAN or other lines due to the silkscreen.

[@phelyan]

Wait, the voltage regulator isn't even connected to anything, either...

[@LEXXIUS]

All these are for show, soldered just enough to not fall off the PCB.

[@dykodesigns]

So, this is just a fancy led flasher!

[@oGeesKeeMasK]

They work, I have that model ( couldn’t for the life of me find that reset button) and more vehicle specific models that I use when I tweak my cars. Saves me 4+ gal. of fuel as long as they’re used correctly and quite possibly under certain conditions.

[@supernova6486]

I would love to see you bust the IAT resister scam that promises more HP.

[@richcharlijohnson1112]

I do engine Remapping and yes you can save fuel through it but it’s a case of flashing new software onto the ecu. At the very least it would need a canbus chip on it
