Very glad youre happy with it.

Went out that night and flogged it around the streets for 30mins or so after warming up. Just after leaving work tonight I had just under 1/4 tank left. It had done over 700km so far, had 230km left and my avg fuel consumption was 5.4L/100km! Needless to say I was highly impressed as the best I could manage before the St3 was 5.7L/100km. I filled the tank up again tonight before I left Sydney for the trip home and I'm currently averaging 5.0L/100km!!! At this rate the ST3 will have paid itself off after 1 year because I do over 40000km per year. Fantastic!

As for performance. It's a bloody beast when you shift the DSG into "S" mode and this coming from a former R34 Skyline owner. It has loads of torque and just wants to keep accelerating. The power delivery seems to be smoother, more linear which makes the GT experience even that much better then it was stock.

The ST3 is definitely the best bang for buck out there right now. I got a huge performance gain without burning a hole in my pocket AND it will pay itself of by returning better fuel economy, so in the end it costs me nothing!

Yep it's a great product and fantastic value for money, but I wouldn't get too carried away just yet with the economy. For whatever reason, the fast road map (on my GT TDI at least), makes the trip computer even more optimistic than it was previously. In my case, where the trip computer indicates an average of 5.4L/100km, the actual average when manually calculated is around 5.8L - 5.9L/100km. Interestingly, when I use the 'Economy' map, the trip computer is almost spot on.

I have been doing an experiment over the past 4 tanks, where I have run fast road for 2 tanks and economy on the other two. I have filled up from the same pump on all occasions, the nature of the journeys and my driving style have been extremely consistent throughout, and all 4 tanks have returned almost exactly the same distance, and a calculated average of 5.8L/100km.

Two tests for each map is hardly sufficient replication I know, but the results were so similar on every test that I'm pretty confident I could continue to replicate them over and over. Therefore, I can only deduce that the economy map does not actually provide a noticeable improvement in economy over the fast road map. The fast road feels appreciably stronger too imo , so I can't see any value in running the economy map anymore.

My next step will be to run the factory map :eek: (the things we do in the name of science) for a couple of tanks to see if the chippedUK maps do actually provide an improvement in economy over stock.

I'd be interested to hear other people's thoughts on fast road v economy, and some manually calculated fuel economy results.:)

Cant comment on the difference between the FR and Econ maps but it is known that the MFD is a out a tad when it comes the the displayed fuel enonomy vs real calculated figures.
This can be adjusted a little using VCDS

Maybe if you drive for economy with each map (ie very gently rather than your usual driving style) you might see a difference in fuel consumption(economy vs stock or FR maps) ?

hey logzy, is there a map/ unit for the polo tdi, by any chance?

Yes, the ST3 is available for the Polo TDI.
What year and engine size is your Polo ?

We have an MY09 TDI DSG Eos on order.

I realise this has the new-spec TDI engine but I would be interested in upgrading it once the engine is run-in.

sorry for the late reply logzy.....

my polo is a 2007 build 1.9 polo tdi.

im also looking at oettinger and revo, but the fact that in earlier posts you said that the "factory" map is also available on the switcher thingy, that it actually puts it back to the factory map as opposed to what it THINKS are the factory settings, is also very interesting to me- im keen to find out more....

cheers! :toast:

Is there any update on the firmware for the ST3 to clear the codes?

FR is out by approx 0.5L/100km for me. ECO is also out but I have not measured it.
