Upgrading 90Tsi

[khonfahm]

Sold the 90 Tsi, with the ECU chip.

It was an amazing car. Great fuel economy.

Upgraded to a 2.0T Quattro A3.

I really think it wasn't much of an upgrade.

Always remember that power to weight ratio is a huge indicator in your cars performance! (1250 vs 1550 Kg)... ( I didn't realise the quattro was so f---en heavy)

The 90TSI with a chip is probably the best car I have ever driven. Fuel economy, performance, just generally ample amounts of fun!

Okay,

So I have purchased the Bluefin superchips unit.

Had a lot of issues and hiccups with installing it...

Final product is GREAT. But if you are not computer savvy, rather GO APR!

Reason you had issues with the Bluefin was because of the 6 hour APR trial you had installed. It leaves behind the APR version of your stock file, not your ACTUAL stock file.

guys, for those who are thinking of a tune for their car, can i just point out that there are more than 2 tuners in australia:

apr
giac (seem to kill everyone at melbourne dyno days)
custom code
superchips / bluefin
dna (ridiculously smooth dyno plots)
revo technik
evolve technik
viezu / chippeduk
etc etc.

take your time, do your research on here and other forums, and good luck!

I just had my Golf R tuned with a DNA Tune a few weeks ago (previously had a Bluefin). The DNA tune is alot stronger than the Bluefin, especially above 4,000rpm.

hey Buller ya im going for DNA once i can. im presuming smooth dyno plots is a good thing?

Excellent value for money and good service.

you bet, mate.

smooth dyno plots = smooth delivery of power, which in turn = smooth driveability. im not too clued up on just how it all works, but one could presume that an inconsistent (flat, then spikey) dyno curve would mean flat spots, followed by unpredictable shoves in the back, in the real world.

a smooth curve means smooth driveability, which is much more of an asset for a car to have when you're actually driving it on the street, and not simply shooting for the stars in terms of kw bragging rights.

either way, if you're going for dna, you will not be disappointed - VERY very nice dyno curves (and no, they dont pay me to share what i've seen of their dyno graphs in the past)

Will be getting my car dyno'd in a few weeks, so will hopefully have another good result for DNA.

I did have issues with the APR trial on the car.. but I had more difficulty setting up the bluefin on windows 7 on my computer. In the end, had to go out and buy a portable dvd rom for my netbook, and cause it was running windows xp, it installed easily.

I'm sure they have adjusted the windows 7 capability by now.. but back then, I had a lot of issues installing the bluefin unit software into my computer.

The AWD also adds a fair bit of extra rotational inertia to the drivetrain as well as just overall weight

Higher rotational inertia means more body roll?

I think in classical dynamics; it is a measure of an object's resistance to rotation.

So the heavier car, should have less body roll (theoretically, obviously a lot more to consider).

I found that the 90TSI, had a lot less body roll than my Quattro 2.0T. So it goes against theory. Thoughts on this?

Nah, it slows acceleration which is why AWD cars don't get great figures on inertial dynos compared to 2WD cars with similar engines (the drive train is the path from the engine to the tyre contact patch)

Just found this in depth info on the 90TSI engine if anyone is interested > http://tbr.gr/122hp/SSP_405_1.4l_90k...rbocharger.pdf
