Hi,

Hope someone can help me.

I'm looking to get a 1.8T Mk 4 and I'm wanting to get it remapped in the future.

I heard that theres a difference with the older engines to the newer ones.

I've seen one that I might get, its an S reg so would this be a problem getting maped?

Thanks for your help guys

It's not a problem getting mapped, you just won't make as much power. iirc its post 2000 x reg that have dbw (drive by wire) before that it will be ndbw (non drive by wire) and and agu engine code.

Remapped you're looking at 190 ish on ndbw and 210+ on dbw

Oh I see, So really, I should look at getting an X reg + if im looking for more power increase on the car.

Thanks for helping out, much appreciated :)

An ARZ engine is DBW but wont get you over 200bhp due to it lacking the K03sport turbo.

Best bet would be 2001 onwards - AUM engine which comes with K03sport turbo.

If you do get a non dbw (AGU) or the ARZ then you could always change the stock K03 for a K03sport then custom map it.

How do you tell if the car has the ko3sport or just the normal ko3? and does this make any difference to the cars standard power or torque or anything or is it just tuning possibilities?

Check the engine code - AGU and ARZ have ko3 and AUM has k03sport. Standard all 3 make the same power, you can just get more from a remap with a ko3sport.

There's a few wrong answers to your question on here about the arz

Ive got an ARZ. 1.8t GTi

Arz's start on 2000 W plate.

when you chip an ARZ (REVO, custom code, jabba) you do get over 200bhp.......The ARZ will make between 208 and 211bhp.

Look on the jabba website for ARZ figures, or contact revo/cutom code and they'll tell you the same[:D]

The ARZ will not make that kind of power due to it having the poorer K03 turbo instead of the K03sport which was fitted to the AUM and AUQ engines.

The K03 will not flow as much air as the sport at higher rpms hence lower BHP gains.

i have an AUQ the 1.8t 180bhp version but my remap only takes me to 200bhp why is this ?
Thats low for a K03sport based car, who's is it?

I have the same AUQ engine and make 235bhp though I have a few bolt-ons also.

Revo 4bar would make around 212-215bhp on an AUM / AUQ.

According to jabba and revo ur wrong mate[:p]

are you giving us these facts because youve owned an ARZ b4?

Have you checked the jabba website??.......Give it a read and be enlightend on the pleasures of running a 'poor' k03[:D] with DBW with OVER 200bhp

LOL

Can we get this cleared up once and for all, everyone states that AUM was 2001 plus, but in fact it was mid way through 2000 that it came out.  Some X plates (like my old one) are AUM.  You really must check the stamp on the engine to make sure.

According to Jabba anything is possible (joke!!) [:p]

Well it seems Jabba do state 208-211 on their site.
Anybody actually got that on an ARZ?

So the only difference between the AGU and ARZ is that ARZ has fly by wire.
How does this enable the ARZ to make more power?

Like you say though Gary it is Jabba who is stateing that, my mate who has a Ibiza 1.8t with a Ko3 gets just below the 200bhp mark and thats with APR.Cant see how a Ko3 can get the same power as a Ko3s.

Star Performance,my only real gain was the torque up to 234lbs car is standard with only a k&n panel filter,hoped for more bhp,but torque will suffice[au]

I have an ARZ and was looking around at what remap to get - the one
thing I've noticed is that Revo refer to the cars by DBW or non-DBW
(i.e. pre-2000 or post-2000 cars) so I feel they're making the
assumption that all DBW cars are ko3sport.

I'm no mechanic but I too fail to see how a ko3 DBW can make any more
power than a k03 non-DBW and even if it does the difference must be
marginal. With that in mind I think 190bhp is probably a fairly
realistic figure to expect from remapping an ARZ.

As I don't plan on tuning the bejaysus out of my mk4 I decided to go
with Upsolute because at 360 euro (vage.ie group buy) it's 450 euro
cheaper than Revo!

I think the DBW engines also get VVT and possibly bigger injectors, so even if you have one that runs the k03 turbo they put out a little more than the non-DBW AGU engine.

My A3 T Sport was a '99 non-DBW and put out 200bhp with an AmD remap and Milltek cat back system. Possibly it would have been more like195bhp from the remap alone.

Heres some more info

Adding VVT and slightly injectors will not make a difference as the
turbo can still only flow the same volume of air, and unfortunately it
is on the limit at 200bhp.

The ARZ DBW engine didnt get VVT, that only came with the later AUM and AUQ engines.
In any case I believe its sole purpose is to help with emissions and in no way increase performance.

The flow of air by a K03 compared to a K03sport is exactly my point - AFAIK thats the only real performance difference between the AGU and ARZ.

Upsolute, Revo and APR both get less than 200bhp with an AGU and I expect the ARZ will be very similar.
