Isnt the mk2 an MPI? Or won't that make a difference?

That, I dont know, but if it were MPi, then yes there'd be a fookin' huge difference!
Im just going of the logic that all 60 engines up to 2000, slot nicely into the Cinq (I presume that Mk2 came out around 2000 then..), so theres a high possibility i'm talking rubbish!
Right, Im getting getting lost in all this teckno bable you lads r on about. I have a Punto MK 2 Sporting 1.2 16v 02 reg with an eco-tek valve fitted to the brake servo pipe. I rag the nuts of my punto daily and I get bout 30mpg with it on, dont really know if that was an increase in mpg as I cant remember what it was like before i fitted it. but any way what i wanna know is can the eco teck valve do any harm to my enegine? Im think no, as on eco-tek's web site it has a punto sporting Mk2 as an example www.ecotekplc.com/more_cars_22.htm and surely they give out false info?
You're right the 16v MK2 is on their site. I'd seriously doubt there are any issues with that. It's the MK2 8v where the concern lies.
I'm going to remove mine regardless. Doesn't do a huge amount (I happily get over 50mpg with the Ecotek off if I'm not ragging the car).

my first relpy about removing it was to the guy with the punto60 (mk1) which is SPI, and i know i'm correct on that one.
The MPI i dont know, for emissions reasons is suspect they'll all be mpi nowadays. Tom, you have/had a punto75 (mpi) head - what say you with regards to its inlet fannymould?
dave, where abouts on the manifold does your brake servo line come from - is it off down a 'branch' of the manifold?

Heres a pic of where the valve is fitted:

Lol how crappy does my engine look 
I really can't believe it runs!
Can you tell from that picture if only cylinder no.4 is affected by the valve?

I'll back Arc up on this one.
Ecotec mistakenly started saying that Clubcento endorsed the use of the ecotec valve on their website and forum, I took issue with this as we bloody well don't - for reasons the ecotec guy agreed with.
On an SPI cinq, sei or Punto 55 / 60 the brake servo tapping is directly above the intake to no4 cylinder on the intake manifold. I forwarded ecotec a photograph and their response (off the forum, oddly....) was that in a position such as this which wasn't central then don't fit one. The ecotec needs to be in a place where the distribution of air from it is spread evenly across all 4 cylinders:
wolfrace, the mpi looks to be ok in this instance, it's the spi ones that are a problem
You could fit one to a SPI fire engine, but as mentioned previously you should do something along the lines of drill and tap (off the car, naturally) the plastic spacer under the throttle body or the intake manifold to fit it.
I'm a born cynic mind, and to me what the thing does is to add more air when you're at part throttle - which the lambda sensor should compensate for, incidentally putting you back at square one - so I wouldn't buy one for mine. There's a few websites out there explaining in technical detail when and where the ecotec works and what it does, a scientific mind says it's all a load of poo.

Someone explain to me then why the hell the fuel eco on my car has greatly improved if this device does not work!!!!!!!!
ok, if it is working what it means is that the ecu is putting in less fuel than Fiat intended - decide for yourself if that's a good thing.
On the SPI cars there's no mass air flow meter, so the ecu relies heavily on the lambda sensor to gauge mixture - if your car has a mass air flowmeter then the ecotec will be adding air after it, effectively fiddling the system and making it run weak.

because you spent £50 on it, and are telling yourself its helping
maybe you can use this in conjuction with one of those "chip mods" off ebayfixitagaintomorrow said:
lol!
.... and one of those magnets round a fuel line, oh..oh..and some of those tablets you put in the fuel tank
Sorry, shouldn't take the mick. Think of it this way though - Mercedes spent a fortune trying to develop the turbulent air system the ecotec allegedly induces and gave up. It was worth about 2% improvement on mpg but with hugely complex labarynth manifolds etc. - not just a cheap pressure relief valve in reverse. If it worked properly, wouldn't it be fitted to all new cars from the factory?
Sorry if I sound cynical, but that's probably because I am cynical.

Thanks for clearing it up It doesnt actually add a large volume of air when is is activated so I cant see it leaning the mixture up that much They say it disturbes the air molecules causing a better burn..........but could be a load of crap, so i'll say no more apart from its staying fitted

..oh and just to add, the nature of the device means it can't improve the engine's power output as it's closed at full throttle. Ecotec had to remove this from their advertising due to an upheld complaint from the american version of the Advertising Standards Agency IIRC.
