^^ link above with details, improved throttle response and reduced exhaust emmisions dramatically and also around 8-15% more economical on fuel, has anyone fitted one or two to their cars? seems a good deal for around £50

I think the reviews on the site say it all, 2of 3 say its crap, most these things are! Best way of achieving fuel economy is to get an LPG set up its half the price of petrol!

These sort of devices do actually work but ONLY under a very specific set of circumstances.

What they appear to do (as I understand it) is to introduce a small amount of air into the fuel that passes through them. Now, for the specific set of cirumstances...

If you've got a carb setup that is running rich, an air leak helps to lean things out a bit, if its running too rich you need to adjust the mix. If you've got an electronic fuel injection system, it'll run closed loop which means it will compensate for any air leak in the system and hence the device will have no effect whatsoever. If you've got a carb setup that is set up spot on, and the leak leans out the mix, you're going to lose torque, power and fuel economy.

Not quite, no fuel goes through the ecotek valve. Intead it just bleeds some air into the inlet manifold when the pressure is low enough. It's complete snake oil, and the people insisting they get more power and better throttle response obviously don't understand that the device stops functioning when the throttle is opened. It should also be obvious it will never work in a forced induction system when there is boost present.

As you say it's possible the device could give improved economy if running carbs or open loop injection that is not optimaly set up for economy.

This company have been in trouble with the ASA for making false claims, and run (or at least used to run) a highly censored forum where even the slightest awkward question was deleted.
