Polo GTI APR ECU Upgrade

[alias_vw]

I notice that the 1.4 TSI Twincharger page on goapr.com lists the Polo in the vehicle application guide.

Yep. Anything on the Aus site?

From reading, my understanding with the 7spd DSG installed in the the Polo GTI is that it's maximum torque load capacity is 250Nm.
What are the thoughts on this figure and if it is indeed correct? Also how is the long term reliability going to be when the engine output is increased?
Cheers,
Trent

Hey Trent, my thoughts are that it's just like the 6sp DSG has a "350Nm capacity". No one cared that the manual also had a 350Nm capacity, they'd just flash and upgrade away. But because the DSG is new technology and expensive to repair, everyone was cautious.

Of course, now we've got Stage III cars running around with 515Nm of torque and the 6sp DSG is fine as long as you're not track racing or constantly participating in the traffic lights GP!


The 7sp 250Nm DSG obviously won't scale to anywhere near those levels. The clutches are dry and single plate instead of multi. But aftermarket tuners have already been running around 320Nm for a year or so on the Golf 118TSI.
So I see no reason that the Polo GTI wouldn't be able to handle at least the same.

Really looking forward to putting this on my GTI.

I will more than likely be getting the cold air intake as well (if/when it's available).

Sorry for the delays, should have our car in the next 10 days

your stock car? or your tuned car?

Guy_H is the owner of Harding Performance. They the local arm for several performance brands, including APR. The car will be a stock (unmodified) Volkswagen Polo GTI, but they will use it to coordinate with the USA based APR engineering team and create and validate the ECU tune for the Polo GTI. From the sounds of things they'll also have more than just software in time...

Does that answer the question?

sounds great!

Car gets to the workshop today

[yellow_cake]

pardon my ignorance but how long does it take to engineer the new parts?

It depends on the amount of testing needed, if we get the exhaust right the first time, one prototype, and a couple of months for final production / testing. If we have to make changes (for noise - internal / external) it adds a couple of weeks per change.

This Polo exhaust will be slightly different as we have never done a twincharger before. BW are supplying APR with the compressor map data So we will start stage 2 calibration there.

Intercooler - This polo looks relatively simple - flow analysis of the standard one is first, then selection of a core & end tank design next - obvious data logging & testing, so 4 weeks for a prototype, 3 months for production (if it can be bought to market for a reasonable price).

Calibration files are being prepared for stage 1 software as we speak.

Do you have an indicative price on a Stage 1 tune yet? Too early to dare?

What all of us who are waiting for our GTI's want to know is did the car arrive as promised and have you had a drive yet?!

The GTI is there ... saw it with my own eyes .... in initial stages of dismantling .....

More importantly .... and I think you Polo guys (ex Polo GTI myself) should make more noise about the fact that Guy traded a Golf R in on the Polo GTI .... .....
