THE ECOTECH VALVE THREAD.

Ford Fiesta ST2
I wont chill out when people make un called for remarks. I dont care how well liked you are, i dont find that funny, but whatever floats ya boat.
And that question ui cannot answer, maybe all these techies just believe what they read on paper and dont give it a fair go. Its something Ill never know, and am not bothered by due to it working on mine, and stuff everyone else who doesnt believe it! 52 posts is def the end for me, goodbye!
lol, I would but he will stick it in his petrol tank and claim another 50+ miles per tank and a lot better throttle responce
Alex, it was said jokingly, Its mostly chavs etc that believe the noise is cool and think that they work hence my comment about burberry tracky.
Please stay........who else can i ridicule in front of my many friends
40 miles more on a tank could simply be a change in your driving style, weather, location etc.
Have you ever read ecoteks installation instructions? Honestly theyre so bloody vague its unreal...IIRC something along the lines of "turn until theres a small whistling at idle" - mean FFS if it actually worked its more dependant on the installers hearing or definition of a noise rather than their mechnical ability! Ive personally done 3 installations a dntryied various "settings" - all of which did bugger all!
Hes right its not going to run becuase it doesnt work so yeah, "its all good!"
As the author of some of the web pages referred to at the beginning of the thread (and something of an expert on Ecotek, following dozens of letters to and from their solicitors
) maybe I can add a few thoughts...1) Alex_Gregory does have a point. The valve can affect the way your car drives, since it effectively stops the throttle fully closing and so the revs stay up on a gearchange (and probably pick up faster when you stamp the accelerator pedal, too). The size of the effect varies according to the car and how it is set up - in many, or even most, cases it will have no effect at all. And for every person that likes this change, another person will hate it and prefer the "unmodified" characteristics.
2) It doesnt improve power or torque more than 1 or 2% (if that), except in the transient case described above. Even Ecotek themselves accept this.
3) It also doesnt significantly improve economy or emissions on anything built after 1993, unless your car had some underlying fault (for example running too rich). Again, Ecotek themselves accept this. People who see 10 - 20% economy benefit are inevitably being fooled by changes in driving style or journey type.
See http://www.fuelsaving.info/ecotek.htmhttp://www.fuelsaving.info/ecotek.htm for the gory details...
Thats just b****cks. Why would I drive 60k miles differently just to prove something works. Talk sense mate. That is the biggest pile of crap I have heard from someone. I rag it whetehr its on or off, as I get 40 miles more with it on go figure what I do. ALthough from your previous comment dont think you can figure.
People always use this excuse and again its ridiculous. If Maxogens are the best thing for a car, why doesnt everyone use them????? If stainles exhaust are best, again why not on your average car. If the Trophy benefits so much from Sachs dampers, why not a dynamique..... Think you will find answer same. And an ecotek is just a widget that may or may not work, dpending on fitment.
in answer to driving style and betetr mpg. I drive 26 miles each way to work at same speed and it takes me same time. I do not go over 70 until oil temp is up and then have a period of 80-90 on with rest being 50 and 30 mph. Same every week. Milage per tank increases with it on. Dont change my route or driving to make this happen, it does it with the ecotek on.
Sigh...
When Ecotek themselves tested the valve under controlled conditions - that is to say, fixing all parameters other than whether the device was fitted or not - they got 1% fuel economy benefit. On the other hand, it is very well known that variations in driving style, journey type, traffic, etc can give easily 20% or more variation in economy with no change to the vehicle at all. Thats why we sceptics say that any change you see with the valve fitted is almost certainly not due to the valve itself.
Most cars dont have Sachs dampers or stainless exhausts because they are relatively expensive for the benefit they give, and most customers wont pay the extra money. But if you really could save 15% on fuel bills for £50 just about every new car buyer would pay that (why pay £500- £1000 extra for a diesel when a petrol with a "widget" gives you the same economy for a tenth of the price?)
However, if the change is mostly just to driveability and throttle response then its a fair argument; most people wouldnt notice (or even wouldnt like) the change so certainly wouldnt pay £50 extra on a new car for it.

How can you compare expesensive items that do work to this ebay thing?
Why no stainless steel on your average car - cost.
Trophy has Trophy dampers because its a higher model than a dynamique, cost and sales pitch.
As part of the Focus RS owners group we are in contact with a few M-Sport engineers 1 or 2 even use our forum, Now i could tell you word for word what these people think of these ecoteck thingies but non of it would show up as the forum blanks bad language and what did come through would prob get me banned!! needless to say some of the best techs in motorsport DO NOT fit these to there cars !!
I am sure there are technical reasons why something can and cannot work. But not everything can be put down to science. You can try something that shouldnt work and it does, and vice versa. Thats how new things are discovered all the time. Im sure teflon was a byproduct of something else.
All I know that on my car, and some other people have said it too, it can work. On mine it gives me 40 miles extra out of a tank. End off really so what is the point in saying I dont know my own car.
If its a widget off ebay, as stated above, this person clearly dont know what they are talking about. Its not one of those resistors you see on there.
Trouble with this forum is everyone is sooo condesending to others. If one person had a crap clio or one that does that make the claimed performance figures then that is a one off. If a Trophy gets a bad review because it broke down, the reviewer should not have dissed a clio. Some people have such narrow minds. If columbus believed world was flat he wouldnt have bothered going anywhere.
Back to the ecotek. I dont know what claims people expect from one. Many tuners sell them, but then if say a certain IK or cam was rubbish I am sure they would still be sold if there are people who will pay for them.
My ecotek I thought would run lean if that is how I get extra mpg. If it does not according to people who know there stuff then all is good. I wont know until engine is taken apart. If a swirl of air is created and this helps burn fuel better, or whatever, I dont care. If it works in giving me more miles between fill ups then cool. But then perhaps having a smooth driving style which is why I dont shred tyres etc helps. Still drive the same with it off and get 360 out of a tank.
Narrow minds ? so if you have several techs/engineers/tuners that have tested them AND know the science behind it and on both counts have found them to be a waste of time and a couple of blokes off the street who admit having no technical knowledge say it works who are you going to believe? Its like the pub talk scenario all over again, my mate has one and it works or i fitted an exhaust and the car is 30bhp more powerful....
As for tuners selling them tuners are businesses and as long as there is a market for these things then they will sell them. If you took the owner/tech to one side and asked as part of a tuning program would they fit them or do they work, chances are they might be honest and tell you "well no not really"
I dont think comparing coilovers and stainless exhausts is a fair arguement. The cost of both would push prices up a fair bit coilovers arent going to appeal to the majority of owners even those with sport models. Exhaust same story you have the issue of cost and sound levels etc. Even if it was standard spec but manufactured in stainless you have the cost plus the fact no manufacturer wants to do themselves out of replacement part sales a couple of years down the line! Ecotec ? cost to manufacture? about £5 in bulk so if they were so effective why arent they fitted to all cars ?
I had a mate who fitted one, it made no difference other than sounding like a kazoo. Guess where he decided to put it ? yup the bin.
