Differance between 99 and 2000 A4 1.8t

[VR4-S4]

I just have a quick question for a friend. He has a 99 1.8t, and he was getting ready to do a k04-15 upgrade. I noticed that you can do a k04-20 upgrade and that GIAC has a flash for it. The problem is it said for 2000-01. Is there a way around that? I know for my S4 which is a 2000 the flash I have is for a 2001.5+ so all i had to do was upgrade the MAFS. Anything like that going on here?

Thanks

in 1999 or 200, i forgot which year, they upgraded the 1.8t from 140hp to 150hp. i dont see why it wouldnt fit. email the company and ask

[dowsett6]

they also changed engine codes. and changed throttle bodies. the 99 has a cable driven throttle body, and the 00 is controlled electronically.

99:
AEB engine
K03
150bhp
DBC
Prefacelift (2 peice headlights, no fog light in bumper, different tail lights)
Different dash and cluster

00:
ATW engine
K03s
170bhp
DBW
Facelift (1 peice headlights, different tail lights, fog lights in bumper)
Different dash and cluster

I am more there are more differences. And the reason why they had flashed tunes for the facelift is that the ECU is different. GIAC would simply load the file through the OBD II port, as opposed to the prefacelift which required the files to be on a chip solderd onto the ECU control board. The difference between flashing an ECU and chipping an ECU. If I am not mistaken, GIAC can now flash prefacelift ECU's. You should give them a call (or your freind) and inquire.

Cool, so it seems like the only thing that would need to be done is reprogramming the cluster and then potentially having to convert to fly-by-wire. Converting sounds like a PITA

If your freind is not already a GIAC customer, he could always look into other tuners. The B5 A4 scene loves Unitronics. May want to look into it. I run with CTapp. There are tuners that will have that file on the k04-20 for AEB. Do some more seaching.

you can't use the K04-020, that's the turbo the Jettas and Golfs upgrade to. The A4's can use the K04-015. It has the correct wastegate actuator location, compressor housing and exhaust flange.

99-99.5 have the AEB, '00+ have other engine codes.
99 is prefacelift and '99.5 is facelift. Do a search if you don't know the difference between the two.

Here come the search nazis, lol

The reason for GIAC is because thats the only thing available in our area, dont think hes into shipping his ECU. I am also 100% aware of what the 2 turbos look like, but it has been done before, and GIAC has software for a K04-20 on a B5 A4 2000-01.

Also pretty sure that the reason its for a 2000+ isnt because of the lights :p

Where did you see that they have a tune for a K04-20 and are you sure you are not thinking of the K04-23?

BTW the 2000 A4 1.8t has a narrow band and the 2001 has a wide band.

2000 = 150chp stock
2001 = 170chp stock

Also pretty sure that the reason its for a 2000+ isnt because of the lights :p

No its because of different engines, mafs, and throttle bodies - by no means are those minor things...

Seerlah said that already

[VR4-S4]

Where did you see that they have a tune for a K04-20 and are you sure you are not thinking of the K04-23?

I just searched B5 A4 ko4-20 and found some info. Apparently a -20 is the same as a -23.

Here is the link to the software: http://www.tyrolsport.com/index.php?...=180&parent=74

Yeah as you can see in the picture from the 2nd link that the real K04-20 has a long outlet on the compressor housing and the WG actuator is in the wrong spot.

I wonder if Tryol is just using a standard K04-15 file for that setup.

Nope. Different part numbers and different applications.
