APR Presents: North American TT RS 2.5 TFSI ECU Upgrade!

[32vSC]

Oh boy, here we go. As John accurately pointed out, you guys all know that you can't compare absolute numbers from one Dyno to another. Relative differences measured on a single Dyno on different days ...

Another variation is the correction factors used.
And another variation is simple run-to-run measurement repeatability.

[jibbed]

Nice!

You definitely got most out of the run I'd think. 1.7sec 60ft is pretty good...

Very interesting observation around leaving the line with S-Mode off (And magride). Did you compare with/without?

1/8th MPH was consistent 91.2 - 91.4

[YYC Dubber]

Oh boy, here we go. As John accurately pointed out, you guys all know that you can't compare absolute numbers from one Dyno to another. Relative differences measured on a single Dyno on different days is even a weak measure but at least more representative of reality. AWE is very professional and upfront about their measurements and observations. The baseline of my car on their Dyno was 360hp crank and 305hp at the wheel, the APR baseline was something like 375hp crank and 325hp at the wheel, if I remember right. They use that hub mounted dyno, so I'm not certain if that is still considered "at the wheel" or not. I'm not one for getting into the "my chip is better" arguement. They are all researched and developed by professionals that know what they're doing and aside from some of the functionality differences, the end results are much more similar than they are different. Having said all that, I'm happy to share my experience and observations thus far on my current setup.

best real world test will be back to back Vbox comparison runs.
30-130 mph runs and in gear acceleration runs (eg 4th gear 60-80, 5th gear 60-100)


0-60 and 1/4 mile times won't work for comparison because we dont have DSG trannies to eliminate driver technique from the equation.

Arin,

2 questions for you.

1 is Stage 2 tuning available yet?
2 what is the absolute minimum needed to support a stage 2 tune. Would a downpipe be sufficient?

[Arin@APR]

Just beta testing a few things but our intake and exhaust are almost ready. When they are, we'll write software.

[Trbofly]

So I would need th.e full exauhst and intake to hit stage 2. Understood.

Is switching going to actually happen, or is it one of those things you are striving for that may not pay out.

About to call my local apr shop today, and that is th.e only thing holding me back.

Since GIAC doesn't support the iPhone that is.

[Arin@APR]

That's not set in stone. It probably will only require a downpipe.

Engineering says yes it will happen.

Arin:

Can we get an update from you on the current anticipated delivery of "flash tools" to your dealers for the TT-RS, please?

[Arin@APR]

Arin:

Probably a couple weeks. Production was machining tools the last time I checked.

[Trbofly]

Are we any closer to the dealers being able to flash a TTRS? Once again, really, really interested

[Arin@APR]

Yes sir! Tools were cut, circuit boards printed, and software written. Just wrapping it all up.

[Trbofly]

Any idea who the first dealer to get it in Colorado will be?

[Trbofly]

Hey Arin,

Just checking in to see how close we are to having the tune at a local shop.

Thanks

[Arin@APR]

Hey Arin,

Just checking in to see how close we are to having the tune at a local shop.

Thanks

Closer every day!

Here's DPP (DirectPort Programming), The UPD (Universal Programming Device), the CCD (Computer Clamping Device), Positioning Plate A (For TT RS Style ECUs) and ECU Interface A (For TT RS Style ECUs).

[LongviewTx]

Arin:

We trust you survived SoWo and are still functioning on all cylinders.

Can you obtain an update for us on the distribution of the flash tools to your dealers, please?

I completed my third track event this past weekend and have loved the TT-RS as an OEM package. But, it would be nice to have that extra punch on the straights where some of the more powerful vettes have a bit of an edge. Next scheduled event is in July. I'm hoping to be back with that extra power and an APR sticker on the rear window (+ 5 HP I've heard).

Thanks

Speaking with the engineers they are still working on it. Right now, I really don't have any other updates to give. As soon as we are ready to start shipping, I'll let everyone know.

hellloooo

so how is that flashing hardware coming or not coming

[Arin@APR]

It's going well. We'll be flashing TTRS's at waterfest, labor free.

Dealers will have the tools soon. We are shooting for a release in the not too distant future after waterfest.

Oh, and if you stop by the APR website, you can get a sneak peak into the stage 2 power figures...

Will stage2 require an intake or just the turbo-back exhaust?

[tdi-bart]

on the chart it says just exhaust, i will be happy with 420 with just a decat

how about a waterfest closer to seattle beginning of august?

Thanks for sharing! Looking forward to seeing some awesome pics of all the quality RSC turboback exhaust hardware.

But the darn monkey who is in charge of plotting technical data is at it again with those stage 2 plots... he changed the Y-axis scale between the stage 1 and stage 2 plots, making it impossible to click back and forth between them to see how the curves changed!

And don't get me started on the actual grid choices... the stage 2 plot uses Y-axis grid ticks of 16 hp, and x-axis grid ticks of 212 RPM. I challenge you to quickly read from the plot how much torque the car is making at 5500 RPM. Who comes up with this stuff?

You guys execute the tunes and hardware so well, so it's just surprising that you don't execute some of your most critical communication (the power curves) at the same level.

[tdi-bart]

thats what happens when you use iChart, it just looks pretty thats about it

[Arin@APR]

So, anyone want to know what it's like to drive one of the APR Stage III TTRS Development Vehicles?



We just want to thank The Smoking Tire for their true Journalistic Professionalism as it's something often missed in magazines and other media outlets today. They were completely unbiased in their review and we were not even asked to cover their expenses. They were a class act operation and if anyone has the chance to work with them in the future, I say go for it.

[Marty]

No excuses... edit the damn axes.

[Arin@APR]

No excuses... edit the damn axes.

I have no idea what iChart is, but that's not what I use.

[Marty]

Me neither. Still, no excuses for poor charts. The bar is high for you guys.

[Arin@APR]

I uploaded a cluttered chart above. I had to scale the chart much larger so you could read it. Small increments (like 5, 10, etc) nice and all but when the charting software neglects to put the last number in, if it doesn't end on that number, it looks horrible.

Sweet, thanks! You guys really extracted out some nice deltas with the stage 2 setup.

Here's just my 2 cents using that chart as an example for what you'd post on your site:

X-axis: plot from 1800 to 6800 RPM, major axis ticks of 1000 RPM, minor axis ticks of 200 RPM (5 minor ticks per major tick).

Y-axis: plot from 100 to 500 HP, major axis ticks of 100 HP, minor axis ticks of 20 HP (5 minor ticks per major tick). (I'd prefer plotting from 0 HP to 500 HP, but I understand that the tuners like their plots to start higher to show the gains a bit more...)

Viola! All of the numbers become super easy to read from the simplified chart, with minimal data removed for formatting.

[YYC Dubber]

WOW, super excited about this map.

I was going to stay with only a Stage 1 map (it was my experience with the Mk5 GTI stage 2 that it only contributed to top end)

I value huge torque numbers that hit fast and I must say I am amazed you were able to make very significant gains below 3k RPM, especially since stage 1 seems to be unable to do this below 2.5 k.

Now a quick concern; I really like the OEM sport exhaust note and am wondering how using the downpipe will affect this curve instead of the full turbo back...

The factory catback system is not very restrictive so with just the downpipe you should see pretty much the same figures.

[tdi-bart]

Me neither. Still, no excuses for poor charts. The bar is high for you guys.

joke, ichart probably doesnt exist, yet

[jibbed]

Hey Arin,

Curious as to whether or not you saw any gains at stage 2 with intake/intercooler? Or is the turbo pretty much the restriction at that point?

Cheers,
matt

I don't have that data yet.
