For us (the unfortunate) that can't get a remap, and have to buy off the shelf ECU's, a browse through Abt (very popular here in GR as Skoda-GR is official dealer of Abt) shows the following:

For AGU (older 150bhp) -> 193Bhp

pdf in german for 193bhp

For AUQ (vRS 180bhp) -> 210Bhp

pdf in german for 210bhp

However, for the current ARX (4x4) motor and since it's identical to the vRS AUQ (apart from stock ECU), wouldn't the second ECU (210bhp) work just fine?

Currently Skoda GR offers the ARX only with the former (eventhough it says it's for the AUQ) while the latter only for the vRS.

Any ideas?

I'm confused here, otheos. (Also by Abt's site, incidentally, which is a mess, but that's another story.)

You say that Skoda GR offer the 4x4 with the 193 chip.

And yet you have an Abt-Skoda with 217 hp.

So what's going on?

Or would it be that the Abt site - messy as it is - just isn't up-to-date?

Also factor in that fellow chip brewers Oettinger didn't have an ARX chip until I ordered one.

Finally, with Abt's focus on Audi it could that they just don't know too much about the intricacies of the various Skoda 1.8Ts.

Mine has other stuff too, and I'm sure the dyno test was a bit optimistic . Also Abt says the word aproximately, and people here with the 193 ECU have found that to be true (anything from 188 to 217 ). But this is besides the point.

You say that Oettinger only brought a chip for the ARX until you ordered one, yet Abt (and Skoda GR) use the former's ECU for the latter's AGU engine on any 1.8T apart from the AUQ.

So if Oettinger thought they should make a seperate ECU for the ARX yet Abt don't, there's something fishy here (on Abt's side). And still the initial question remains: if the AGU's ECU can be used on the ARX, why not the AUQ's.

Unfortunatelly people here are NOT very knowledgable eventhough they are the official importers of the Abt ECU's. There is an "I know all" mentality that is difficult to put aside and go into the "I'll find out" mentality.

So any ideas would be great.

Oh, fluent german is not my strong point so I got to say that Systran was really confusing too

Don't Abt do a chip for the AUM? That's the 150 hp FWD engine that's replaced the AGU and is also similar in characteristics to the ARX and AUQ, i.e. with a performance upgrade range up to 210 instead of 193.

I know Oettinger already has one, as I happen to know a couple of Dutchmen who have it in their cars. Still, Oettinger deemed it necessary to make a chip specifically mapped to the ARX.

I've been wondering about Abt too lately, having heard stories of Audi drivers having bought an Abt upgrade from 163 to 193. That is making me wonder... The 163 hp version is definitely similar to the AUM/ARX, with the increased input from the old 150 hp AGU due to the bigger turbo and injectors openly marketed, whereas Skoda do not, probably not too upset its bigger brothers in the VAG group. Equally, the standard 193 hp figure on other Audis fits with the 180 hp AUQ engine which is usually dynoed at 193 hp anyway, but which is only quoted by Audi and not by Skoda. So Abt are in fact simply selling a programme that will undo the downtuning performed on the 193 hp engine to make it a 163 hp engine - to put it back to 193 hp. And are asking big money for it - only slightly less than Audi would do for a standard 193 hp car.

Why not hike it up to 210 hp at once, as Oettinger do? That would be real tuning.

So you are right, there's something fishy going here - and I fear the strong ties between Abt and Audi have something to do with it.

And then, why use an ECU designed for the AGU (no VVT, smaller injectors, no DBW and simple K03 turbo) on the ARX, while the one for the AUQ takes all that into account and delivers more.

It's the same thing in Sweden. There isn't any chip upgrades offering more than 193 bhp for the latest 4*4 Octavias.

The reason Audis 163bhp engine don't gain more power than 193bhp is because of the injectors wich differs from the RS and later 4*4 skodas. My friend got his new A4 a couple of months ago. It has the new 190bhp 1.8t wich I think has the same turbo and injectors as the AUQ. The difference is that engine has twin intercooler setup as in the TT225.

That's interesting!

So where does the 163 hp come from compared to the "150 hp" (which is in fact 163 hp) on the AUM/ARX?

I thought all newer VVT/FBW/K03sport were 163bhp but only Audi advertised it as such for (a) to keep up with the Merc 200Kompressor without ( being matched by other group 1.8T's

According to what Audi told my friend it's just a modestly tuned version of the 150bhp engine. Just different software, they said. The 163bhp version does feel quicker than the 150bhp dito.

Exactly my understanding, but apparently Audi told Chrille's friend otherwise. (Or wants him to believe otherwise.)

As I said; the 163bhp A4 does feel quicker than the 150bhp A4( tested both) Would be strange to sell the 150bhp and the 163bhp versions at the same time if they infact deliver the same power :confused:

But they did not coexist, or did they? As soon as the VVT 163bhp came about the older 150bhp non-VVT was replaced.

So comparing the two cars would show a difference. What I'm saying is that ALL VAG "150bhp" VVT engines are actually 163bhp, only Audi makes a fuss about it though.

No, I think you are right. The 163bhp engine replaced the 150bhp dito. It would be strange if a 2002 1.8t 150bhp didn't have the vvt. Right? Hoewever, back then( last year) my friend had another A4. A 2002 1.8t 150bhp. When the 163bhp A4 got to the dealer we testdrove it and it sure felt quicker than my friends car. After that he ordered the 190bhp A4 wich was delivered a couple of months ago. Really nice car! But the price tag is redicoulous He could have bought 2 Rs's for that kind of money:rolleyes: :rolleyes: :confused: Badge snobbery some would say. I would definately agree...

For AGU (older 150bhp) -> 193Bhp

I has a 2002 AGU engine. Were I can get this info in english?
