APR ECU and APR HPFP

[Romp]

What kind of power outputs does GIACs EUC pump out?

Look up sammy's car... He just did a 222kw atw... He has a k04 tho

Think he did 171kw with dp and intake

Hey guys just bought a 2006 golf gti and was interested in doing the following things:

APR ECU
APR HPFP

Apparently from this i get the power will go up from stock 147kw 280nm to 188kw and 411nm. The APR HPFP from what i'm told gives approx 20kw at 3000rpm-5000rpm which i think is quite good.

Has anybody fitted the HPFP and what are the results and opinions? ALso do i need a diverter valve if fitting an APR ECU?

Also i know fitting an ECU doesn't alter insurance much how about when fitting the fuel pump? Any advice on this subject guys?

Sorry another question do most guys who fit the ecu upgrade brakes and or suspension?

Thanks in advance guys.

I have a GIAC tune with the upgraded HPFP, intake and downpipe and at the last dyno day in Melbourne I scored 164.8kw.
No other "Stage 2" car came close.

With APR you don't have the option of picking whatever brand of HPFP you want, if you buy a fuel pump that ISN'T theirs you have to pay to have the tune upgraded to account for it. You don't have to with GIAC.

The APR fuel pump is $1700 which is a ****ing rort. I'm fairly sure you can pick up an Autotech HPFP from the US for half that price.

The HPFP makes the car feel a ****load stronger in the midrange than what it is stock. I disagree with John. An appropriately tuned car with a HPFP and downpipe makes a massive difference in power in the midrange.

I also have a dyno graph to backup my results.

Speak to Arthur at Exotic Cars and he'll be sure to help you out.

John, I'd love to see a Stage 2 DNA Tuning GTI that compares.

Just want to clarify that our "Stage 2" file is not the same as your Stage 2 file in terms of boost. Our "Stage 2" is a file that makes no requirements for other modifications; instead it is a level of tune that is more aggressive than our "Stage 1" and is safe to run on a stock vehicle, as in the case of David's Octavia which did 150kw on the same day as your car.

We have a further level "Stage 2+" which is designed to accompany downpipe/intake/intercooler upgrades which would easily lift the performance level up to if not beyond the 160's. In fact, even on his current tune, downpipe/intake upgrades could quite easily bring the car close to the 160kW mark on the same day.

I hope this clears up any confusions or misconceptions people may have regarding "Stages"; what one company defines is different to another. We rate our Stage 1 program at 184kW, Stage 2 at 188kW, and Stage 2+ at 196kW. As such, the different in peak power is greater between the 2 to 2+ than between the 1 & 2.

OP, John has gone out of his way explaining the general principles of 2.0T tuning.
He has conducted himself well, and offered a great product at very competitive prices.

As for the basic ethos of tuning, there is plenty of information on here, vwgolf.net, golfmkv.com about the options (software, DP, HPFP etc). It would take a lot of strain off John you finding out what you want to do with the car, and what you need to get there. Then make contact with the relevant people.

Much easier, HTH

Well said

I suggest just going for the APR ECU as their fuel pump will not add power to your car. The fuel pump may come in handy for Stage 3 setups but you can always get that further down the track.

As you can understand, having the capacity for more fuel delivery is great, but if the stock K03 turbo is unable to generate enough air/boost to require this extra fuel then it is pointless; ie. the fuel pump itself does not magically add 20kW.

The fuel pump adds a nice chunk of mid range torque where the standard cam driven pump struggles to supply enough pressure (more revs = more ability to supply fuel).
Adding the pump allows the tuner to increase performance where it really matters. Its a night over day comparison imo. Obviously the fuel pump needs a tune that takes advantage of the extra fuel available at low rpm though.

Fair enough John, but note that the Octavia runs a TSI engine, not FSI. Different beast, you can't compare the engines at all.
A GIAC MK6 GTI (TSI) in Sydney ran 172kw with intake/downpipe.

It's a BWA code engine, Bosch MED9 ECU platform, just like the Mk V GTI. It is one of the last second gen Octavias, so despite it being relatively new, it is not the new "TSI" engine as in the third gen Octavia.

However, we rate the Mk V and Mk VI gains the same, so I can't imagine the Mk VI's posting much higher figures. 172kW on an aggressively tuned 2.0T + intake/downpipe on a different day/different dyno sounds about right though in terms of relative performance.

Ah okay, fair enough. Interesting though that you consider TSI/FSI gains to be the same though, TSI engines always seem to have the clear advantage.

I don't set the specifications for DNA Tuning UK's ECU upgrades; as such I can really only go off the information provided to me. I haven't seen solid evidence that the 2.0TSI is stronger than the 2.0TFSI, especially when tuned.

Actually, taking a look at the specs of the other tuners, they are also virtually identical to their Mk 5 counterparts, so yes, based on that, and also subjective comparison between Mk 5 and 6 tuned GTI's, they seem to be the more or less the same power-wise. I'm looking forward to seeing comparisons between some Mk 5's and 6's on the same day, same dyno, same tuner, etc. though for sure!
