Polo platform + AWD + 2L TSFI engine

Maybe this is what Audi will call the S1

A1 + AWD + 2L TSFI engine (155kw etc)

I bet the cost will be easily more than a Golf GTI. The Polo GTI is still better as far as "bang for buck" Will be interested when and if it comes to Australia But then again, I'm biased

Heh... audi have put it with a 6 speed manual.
They couldn't use the 7sp audi 550nm dsg, as it weighs 140kg and is huge. They couldn't use the 7sp 250Nm VW DSG without doing changes to it to raise the "official" torque rating. The Audi versions of the TFSI also have 350Nm instead of the 280Nm of the VW versions. I wonder whether the 6sp DSG would fit?

[Guy_H]

I'll have one please

[Sharkie]

I'll have one please

Me too thanks

[Hooti3]

I personally don't like the look of it.

The concept of the car is great, but the actual exterior of the car is not very nice.

**flame suit on**

[Guy_H]

I'd paint it flat black so it would go unnoticed!

Interesting point Corey They can't put the 7 speed DSG behind it because then it would prove that VAG have been fibbing about the maximum torque capabilities of the gearbox, which would be similar as to why the Golf R has a de-tuned "hot weather" ECU program so not to make it as quick, if not quicker, then the VAG hero hatch in oz being the S3 or the TT-S even

Marketing, it's a bi**h sometimes in a small maket hey!

ECU upgrade here we come. What's happening Guy?

[Corey_R]

Well... whether it's the VW version of the 2L "TFSI" without valve lift or the Audi version of the TSI with valve lift, APR have ECU's available for both already. It'd therefore hopefully be a quick task of qualifying the tune on the S1 with it's particular base tune, intake, sensors, drive train etc.

So non-valve lift we go from 155kw/280Nm to ~189kw/402Nm. Or with valve life we go from 155kw/350Nm to ~175kw/451Nm

Hi Corey,

I am a total newbie re performance tuning such as this. Love the idea of re-mapping the "brain" but still have concerns that it could stretch the vehicle mechanically beyond safe limits (i.e. causing stress and wear that will possibly materialise in operational issues, that wouldn't have occurred if not tuned).

I guess my questions are

1. How does a paranoid person such as me convince himself that he's not inviting problems by tuning the vehicle as you describe

2. I understand that the remapping is reversible, but would you have to do this prior to every service so your dealer doesn't detect that you've messed with it? I know it might not be obvious that you have tuned/re-mapped, but it would seem to me that manufacturers and dealers would proactively go looking for such modification so as to flag a vehicle as warranty exempt

Cheers

Frostee

[GTI JOE]

Excellent questions Frostee. I guess I am paranoid when it comes to these modifications as well. Hopefully Corey can shed some enlightenment and even encouragement

[Corey_R]

Hey Frostee, you're probably best to go to the Tuning and Performance (inc ECU upgrades) forum so as to not get this thing completely off topic

Joe, I work in IT. Not a techo but been around long enough to know enough that most things you do with data leave a breadcrumb trail.

Aside from the re-mapping vs mechanical impact of going outside manufacturer delivered tolerances (the light that burns twice as bright burns half as long scenario), I'd really like to understand at a data level how this mapping interacts with the data storage devides on the car.

You can delete files on a hard disk, but unless you overwrite the data etc it's all there to be recovered. I'm just concerned that if VW was hit with a substantial warranty claim they would have forensic hardware/firmware/data logging analysis as step 1 to try to weed out their accountable issues vs those created by those tinkering with the hardware/software. In my reckoning it should be pretty easy for them to set-up such analysis, given they commissioned the hardware they use in the car.

It's available now, its just the dyno & marketing numbers we are waiting on at this stage. I'll send you a PM
