Is it possible? (Upgrade 150HP-180HP 1.8T)
fjhu...@hotmail.com
I own an A3 1.8T, 1999.5 (no drive-by-wire, yet labeled as a 2000).
Great car, still I have a craving for more power.
I wouldn't want to put an aftermarket chip in my car(I cannot imagine
losing the warranty at 300 miles!), yet I think the 1.8T is a little
tame in stock form (yeah, right =). I would love to upgrade the HP
rating "the Audi way", that is, using an ECU designed by Audi.
From what I know, the A3 1.8T 150 HP and the 180 HP share the same
engine and turbo. So, it might be easy to think that the difference is
in the ECU. Would it be possible to put an 180 HP ECU in my car? Do you
think Audi might be helpful with this?
I also think that my car not being a drive-by-wire model might cause
trouble, since all the 180 HP models (TT, A3) use drive-by-wire. Any
ideas?
Take care!
Francisco.

110kW engine:
1. e-gas
2. tumble-type intake manifold
3. ecu
4. ASR/EDS/ESP made possible by CAN bus
5. electronically controlled boost recirculation (blow-off) valve
It's probably not reasonable in a cost/benefit sense to try this upgrade,
I'd recommend Abt or MTM sourced upgrades - I have good experiences from
both, both in ECU-only and further modifications as well-form.

the 180hp was fitted with ASR (Electronic traction control), EDS (Electronic
Differential Lock) and of course ABS. The engine was aslo fitted by e-gas
(no cable from the accelerator pedal). The 150 hp had only EDS, ABS fitted
before 0899. On 2000 models (0899) the two engines are fitted with ESP
(Electronic Stability Program), e-gas. ESP includes ASR, EDS and ABS. So the
only difference, due to Audi, is the ecu. I have spoken to Audi (I own an A3
150hp) and it is possible to change the ecu but Audi have made it very
difficult because they have also changed the wiring harness. Your tacho
meter etc will not work if only the ecu is switch. So it is possible but the
costs will be higher than it is worth I think. Try an ABT or MTM chip. They
will provide a certain warranty.
Just be aware of that the 150hp in A3 is not the same engine as the 150hp in
A4. Also the 180hp in A4 is not the same engine as the 180 hp in A3. TT and
A3 share the same 180hp engine. Confused?

A4, and they look pretty much the same (except his car has the e-gas
feature).
My guess is they cannot be the same due to differences in the A3-A4
architecture, the A4 having the transverse engine.
Thank you very much for your info. I am still confused, though, because
the dealer sold me my car as a 2000 model without e-gas. I have talked
to them about the subject, and I have received 3 different responses:
first is that all cars are the same, second is that my car does have
the e-gas (then what is that mechanical link doing in the throttle????
=) and third is that they switched production to the e-wire, but that I
shouldn't worry since my car was sold as an 2000 model, and it will
depreciate as such.
Not very Audi-esque, I think =)

You will then see the definitive difference between you and
your father's car.
Engine, engine number, date of manufacture and so on.

I seriously doubt Audi would do this, but the main problem is that the drive
by wire ECU is a different part from the earlier ECU. They are not
interchangeable. A chip is the most reasonable approach. Audi cannot legally
void your entire warranty in the USA if you install a chip, though they will
likely give you trouble if they think a problem was caused by the additional
power.
My advice? Keep the car stock for about 10,000 miles so that any initial
problems can be corrected under warranty. Then chip it, but stay at Stage 1
level (about 200 hp)through the rest of the warranty period. Pump it up
higher if you desire after three years..
