So after a long wait (like us all) I now have my new vRS and I have had it for a few weeks.

Previously I had a mk2 vRS 170 DSG which my tuning box from DTUK was fitted to which was brilliant, see the review thread here:

http://www.briskoda.net/forums/topic/273668-buying-a-crd-t-tuning-box-from-dtuk/

 

So now I have my mk3 I sent the box back to Andrew who uploaded the latest software to, I know he has worked a bit on the map for the new cr184 and on the dyne the results were impresive - it is good that the figures are backed up by actual results!

 

I have tried my box on my car now once the engine had been run in, I messed around with all the maps and settings and I have settled on 4.1 which is the setting Andrew had his box on when the 235bhp dyno result was achieved.

 

 In practice the box was easier to fit than on the CR170 engine due to the location of the boost pressure sensor (MAP), Andrew sent the new harness needed and it was fitted in around 5 mins securing all the cables neatly with 3 cable ties.

 

On the road it is absolutely awesome - torque is available early and is introduced swiftly but progressively, this should help the life of the clutch instead of bringing the torque in all in one go.  The big difference between the box fitted to my mk2 and the new mk3 is the power further up the rev range 2500 - 4000 rpm, now the pull is relentless and doesn't fade.

 

I though the box fitted to the 170 felt good but this is definitely better (I suppose shown by the dyno results)

As always Andrew has been helpful (as most people on here find he is) and my box was sent and returned to me quickly with the new harness required for the new engine.

 

For those who want to know, the MPG readout will need correcting with VCDS. My testing (calculating it the old fashioned way vs indicated MPG) has indicated that for a accurate reading the adaptation in the instrument cluster needs changing from 100 to 112 with the box set at 4.1

 

To correct a std car with no mods for an accurate reading it needs to be set to 102.  Brim to brim calculations show me averaging 53-55mpg with the box set at 4.1, I do do a medium amount of motorway driving.  Normal journey to work shows 60mpg but my town driving during the weekend brings the average down :-(

 

So to sum up - 235bhp, 505nm, 55mpg, £30 tax and super fun car to drive = very happy customer :-)

Nice review

Thanks for sharing..I am very tempted myself (Mk2 FL 170 CR)

I must say, initially I wasn't that bothered but the dealer took my mk2 (it was 16months old) and gave me a mk3 for no extra monthly cost (due to the 0% APR) and the new car is awesome. Loads more settings and the adaptive bi-xenons are a dream!  

It was also quicker in the higher rev band (std 170 vs std 184) - but now its loads quicker   car generally feels lighter and more responsive and the interior feels much better. Just get one if you can wait for ages that is

Sounds good, but I'm a bit confused as to why a tuning box would make such a difference to the correction for the mpg readout?

The tuning box modifies the fuel pressure and manifold pressure signals to create more power. Problem is the mpg is calculated based on those readings (and some other) so it gives an incorrect reading.

The further you turn the box up and alter the signals the further the mpg goes out.

Hi Brimma - you must be lost - this is the O3 section

 

Not thinking of a JPS O3 are we?????
