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

[tdi-bart]

maybe it's just me, but it seems apr stg1 makes more power than the giac chip + exhaust + cat delete + intercooler... comparing the dyno runs at the wheels, both start off close to each other in terms of WHP stock (+/- 2hp), but apr seems to get 20 more...

Except you can't compare results from different dynos. Someone needs to plot the percentage gain in power across the range for both tunes and compare those results, that'd be a bit better comparison.

It could be that the other mods "find" horsepower that marginalizes the ECU gains. For example, an intake may give you +10 hp. A new exhaust may give you +15 hp. And an ECU tune might give you +35 hp. But all of them together aren't going to give you +60 hp. You might get +45 instead or something. I don't know why. It just seems to be the case with all car mods.

It's a shame there isn't a GIAC TT-RS in my area.
I'd be happy to make some "comparative runs".

Arin, sale ends in a couple of days, did your local dealers receive their tools yet? specifically ELM in my town? Thanks.

ohrly? did you miss how each dyno produced the same stock whp within 2 hp?

[Trbofly]

Bump. Got money in my pocket.

Will the sale be honored when we can actually get the tune?

[Arin@APR]

They don't, but we've extended the sale.

[tdi-bart]

does the sale apply to canada?

[Arin@APR]

does the sale apply to canada?

Our canadian importers set pricing in their own market. Give them a call! www.goapr.com/dealer/

[canuckttrs]

dealers don't have the tools, i think the sale is just meant for people who are going to send their ecu's directly to apr in the mail.

[canuckttrs]

does the sale apply to canada?

it does, but the dealer i spoke with charges an install fee of $100. plus they don't have the tools yet anyways.

[canuckttrs]

They don't, but we've extended the sale.

Is there a good day to send it in or anytime before 1pm m-f?
Thinking of planning on it next week, just need to time it right so i have minimal car downtime with the shipping.

Send it as early as possible.

We get ECUs in at 9 AM typically and ship them out by 5PM.

The cut off time is 1 PM to get it out the same day if it happens to not come in at 9 AM.

Just make sure all of the paper work is filled out correctly with all of your contact information and return shipping method to ensure the fastest turn around time.

Can you recommend a shipper? I prefer Fedex as i'm in canada but let me know which one gets it to you the earliest.

Almost all of our shipments out the door are through UPS.

[tdi-bart]

what city are you in, they better waive that fee if i just drop the ecu off for them...

[canuckttrs]

If you lived in Canada you would know what it really means to have a burning hot supernova hatred for UPS. But i digress. I'll try Fedex.

near vancouver. i'm sure they would, you're just going to have to wait until they get the proper equipment to do it.

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.

[tdi-bart]

AWE Dyno:

Before
317 TQ 323 HP

After
355 TQ 355 HP

Peak to Peak:
TQ Increase:10.70%
HP Increase:9.01%

Max Gains: 51 FT-LBS and 43 HP

APR Dyno:

Before
349 TQ 325 HP

After
407 TQ 370 HP

Peak to Peak:
TQ Increase: 14.25%
HP Increase: 12.16%

Max Gains: 79 FT-LBS and 73 HP

That's a big difference when comparing the delta between stock and chipped. Every dyno will read differently, so comparing peak figures between the two is often inaccurate, but if you compare the delta you can see there's a rather large difference between the two!

I must be missing something. Look at the first page graphs on this thread.

Now I'm confused. What do you mean?

[J662]

This thread is confusing. I have one simple question though:

Where do I go to get a clean install/remap for APR Stage 1? I live in San Diego.

Doesn't the dyno plot show exactly what I said...375hp stock at baseline? Maybe I'm not reading it correctly, but that is what I was referring to. I have no idea where TDI's numbers came from, the links are dead. I just went by the info presented in this thread. My car "only" did 360hp at baseline on the Dyno at AWE. I suspect the difference is more Dyno variation than actual car variation but who knows, maybe you guys got a hot one from the factory somehow!

[tdi-bart]

that is a graph showing crank numbers (375)

if you goto the apr website, they have a graph showing power at the wheels, which was not posted in this thread... and that is the graph i got 325whp from to compare against the 323whp awe got

It looks like the links got cut off.

Here's the wheel data graph vs what appears the wheel data graph from the other company. I believe he was comparing the difference as number and percentage gains between stock an chipped.

Nice work!

[tdi-bart]

hmm no 11's? do 7k and drop it like it's hot, it will hook you will see haha

but really i dump it around 4-5k and it takes off so hard...

how would you say the chip compares to stock? also cat delete, noticeable diff in power or no?

Not sure on test pipe power honestly, other dyno's show 7-10hp on stock software, no idea on chipped cars.

As far as the software goes, it's like flipping a ballistic missile switch. No comparison at all, night and day. I have a "low profile" gasket that seals the bay to the hood/windshield area. That & the added boost make the turbo & BPV noises loud as hell. It's like driving a totally different car now.

Cant wait to fully de-cat and try the 100 octane tune.

[MitchyRS]

12.29 @ 116.2 isn't a bad effort. What was your 60ft time. You should be aiming for 1.7x's

Tyre pressures low, not high. F 28 R 26 (Hot)

As to secondary cat bypass, doubtful they make any power, a couple of horsepower at most, they are more like noise suppressors rather than a power sapping restriction. The main culprit is in the downpipe. Get rid of that cat, dial in a bit more timing (not boost) and bobs your uncle. You should increase trap speed by another 2mph and cut the 1/4 down by around 2/10. You will easily get into 11's with some higher octane fuel, decent 1.7x launch, and a little weight out the car. Front passenger seat - 35kg, 5 min in out job.

Good efforts though.

[joneze93tsi]

Thanks Mitchy.

I was about to gut the primary cat, but APR is supposed to be releasing a nice large catless downpipe that will mate with the stock cat-back. Figured I'd hold onto it in case my region decides to do emissions testing in the future.

Huge difference this time launching vs the first time.

Had about 33-35psi in the tires vs 40psi+
Had the car on non-s (softer magride!)
Left at 4-5 vs 5-6.

Only make 3 passes 1 1.7 and 2 1.8's.

I'm done with drag racing for now. Rest of the season will be Auto-X and maybe a road course or two. I figure by the fall 1/4 mile days it will be cool, I'll have the cat sorted out, good fuel & 100octane file and less weight.

Great times Joneze! What was your MPH at mid-track? Good job in any case!

[joneze93tsi]

Great times Joneze! What was your MPH at mid-track? Good job in any case!

1/8th MPH was consistent 91.2 - 91.4
