vRS TSI Octavia Bluefin/Superchip

[donweather]

I asked this question over on the Tiguan forum but got no response, so thought I'd ask here for better luck at a response.

Can anyone tell me why the Tiguan and Skoda Octavia vRS have different Superchipped figures (for both power and torque) when I assumed they were the same 2.0 TSI engine in both?

Perhaps the figures for the vRS are old (havent been updated for the newer 2.0T TSI engine) and are showing expected figures for the older 2.0T TFSI engine that was used in the pre-facelifted Octy vRS. If you look at the date on the Octy specific webpage it shows "9/2005 onwards" which means that Superchips havent got specific pages/details for the 2 different engines that the Octy vRS has been sold with (i mean the two different 2.0T petrol engines as well - not the diesel).

Having the older design 2.0T TFSI engine in my Golf R, i know that power and torque gains without an upgraded high pressure fuel pump are limited in comparison to the newer TSI engine. This may be the reason for the difference in expected power gains. As the newer 2.0T TSI has a better designed high pressure fuel pump, tuning companies don't have to worry about issues with fuel pressure and can therefore push the tune a bit harder, resulting in more power.

They should realistically have two pages to suit the Octy vRS - one from 2005 - 2009 (or thereabouts) when the pre-facelifted Octy vRS came with the older 2.0T TFSI engine, and another page from 2009-present to suit the current Octy vRS which have the newer 2.0T TSI engine.

Was the Pre-FL vRS a 1.8T?
Edit: nope, the super first gen that we didn't get here was a 1.8T

No it was the same 2.0T TFSI that the MK5 GTI Golf came with. These days they use the same engine as your Tig and the MK6 GTI.

looks like they've shown the figures for the TFSI, i.e. pre-facelift model. The one with EA118 engine.

back in 2005, the RS did not have the newer TSI (EA888 ) engine. it still had the TFSI (EA118 ) engine
the EA888 started appearing in the RS just prior to the facelift being released (in 2009).

meanwhile, the Tiguan shown by superchips, is for 2008 onwards, around the time when the EA888 engine was introduced.

that would explain the difference in gains.
it also backs the fact that EA888 engine gets higher gains than the EA118 engine.
The EA118 engine, however, is much stronger. a reason why the golf r still continues to use the EA118 engine.

Hmmm - how does the DSG cope with another 104NM of twist?

[Tigger]

The real dramas are the front wheels breaking traction I reckon...

The AWD of the Tig is much better suited to power increases....

ive been reading up about the EA118 and EA888 engines and the possible reason why they use the 'older' motor in the higher powered cars isn't due to the fact the EA888 is weaker, its just the EA118 was already developed to handle the higher power. theres nothing wrong with the EA888.

also, I have the Bluefin on my 147TSI, best bang for buck ive bought for the car

Occy vRS?

Did they provide you with expected performance (power, torque) gains before you purchased, and if so, are they the same as quoted on the Tig page/link I posted above?

How do you find the traction issue in first (and perhaps even in 2nd) with the bluefinned TSI?

I have a Bluefinned 1.8TSI. I disregarded their claims because all the tuners only quote the best figures they can record & all dynos are different anyway.

Traction is an issue if you can't control your right foot, otherwise it's business as usual. If I floor mine in 3rd on a wet road I still get wheel spin so there is plenty of torque available.
