im not saying this product works but voltage stabilisers do work in producing power,

im not saying more power= better fuel economy.

but take a look at these, i plan to test one out when i can get a hold of or make one.

some results\
BMW E90 accessories Qmax Voltage Stabilizer Dyno Test Racing Engine Oil Manufacturer
Toyota Altis (2008) accessories Qmax Voltage Stabilizer Dyno Test Racing Engine Oil Manufacturer
Suzuki Swift accessories Qmax Voltage Stabilizer Dyno Test Racing Engine Oil Manufacturer

my internet is crapping out so will post more tests later

they make more power in the lower rpm range (hypermiler central) like i said i plan to test these out for you guyys one day in the future and see how we go, i think there is something to them. (feel free to prove me wrong i like hearing other peoples opinions)

This QMax - I'm impressed, it has a maintenance free fuse.



Thats a mightily compact looking 'exclusive' design of microprocessor, and whats a nano technology grounding cable? Is it a wire?

We should be keeping a scoreboard.

When it comes to things electrical, there sure are a bunch of suckers out there. And plenty of opportunists to take advantage of people's ignorance. I had no doubt this was a scam because:

1) "voltage stabilization" cannot be done through the car 12V accessory outlet.
2) even if it could, the ECU has filtered power already.
3) even if it didn't, the ECU would not operate more "efficiently" to improve mileage.

Put a fork in it folks and take a lesson.

ok,
the consumer report said it makes no significant difference,BUT i didn't say it makes NO difference

whats that all means i wonder.... does it show 2 % versus 25% claimed....
what about if the car was 15 years old?

[EdKiefer]

While I think the % increase are way hyped (if any increase at all )
But looking at this page data doesn't give them good impression IMO .

nanotechnology.qmax nano Fuel Saver Manufacturer,Qmax nanotechnology products, aftermarket performance parts to increase horsepower, less pollution, smoother engine, engine response, deisel common rail engine, petrol engine

Look at the bottom chart data before an after .

Note ; gear = before 4 , after 5

not sure what tour/min = maybe rpm but if that's not a typo it is not exactly fair comparison .

If the car has bad/corrosive ground points I can see grounding cabling helping , then again you could just fix the bad area to bring it back to OEM spec .

[instarx]

Hmmm. it seems that the independent lab's test results data sheet has disappeared from the Fuel Doctor web site.

I also see that Fuel Doctor disputed Consumer Reports' test methods by saying that "Nowhere on the outside of the box do we say it works with new cars". The outside of the box!!? Evidently they did say it in their advertising though.

Shady.

Why would it not work with Hybrid cars, anyway? Maybe because they have a mileage gauge and you can SEE the non-function in all its glory.
