why is aww 1.8t 01 jetta uni stage 2 only 206hp?

[taverncustoms]

what needs to be changed to get the 230hp out of a stage2 2001 jetta AWW 1.8t. the unitronic website says stage 2 is only 206hp but the 2002 jetta is 230hp they bolth have K03s turbos and the same wastegate?

[AmIdYfReAk]

I'm in for this as well, there are a few tunes that differ from the AWW to AWP, then hardware wise they're identical.

But i think the only one that can answer this question is uni them selves.

[sponcar]

Honestly i have always thought the AWW comes with the k03 while the AWP comes with k03s. PLUS THE VVT. but i dont think tuners such as apr, unitronic, eurodyne, revo or giac play with that stuff with tune for stock turbo.

[groggory]

Is the AWW wideband?

Is the AWW wideband?

yes they prob get mixed up because non wolfsburg 2001's have the k03. wolfsburgs got the k03s and wideband. not sure if the 2001 non-wolfy's are wideband i think they are narrowband, that's what i've seen around. i do know if you chip a aww w/ k03s you will get the power as awp. maybe a little less if you have narrow band and k03

And for this I'm glad I have an 02 awp. Keeping it simple and easy.

wow really? i own a 01 jetta wolfbourg edition, I know AWW are wideband but im confused of the turbo. My turbo doesn't have the silencer thing (however it's call the cylinder thing on the air compressor tip) like those from awp turbo does.

[Rod Ratio]

Aww has k03s.

yea, the aww ko3s has no silencer on it mine did not. i need to be a little more clear on my 1st post too. AFAIK all 01 wolfy got the aww wideband setup. all aww got the k03s, most if not all without the silencer. also, AFAIK any other 2001 or lower model year 1.8t golf/jetta was narrowband with AWD engine and ko3.

lol, I'm glad i bought a wolfy i didnt know any of the k03 or wideband/narrowband specifics when i bought the car

[AmIdYfReAk]

See, Now we're all getting into the confusion...

the AWW is identical to the AWP, Hardware/compression/etc minus the small detail of the silencer on the output of the cold side of the K03S.

so whats the deal?


On a side note, my AWP tune works awesome with my AWW.

Lol me either. I guess we both kind of dodged the wideband conversion bullet there.

[Dave926]

I was always under the impression the aww was wideband and immo 2, whereas all the other wideband cars were immo3.

Thanks for the clarification that the aww had a k03s, thought the same as the other poster with the silencer thing.

i dont know anything about the immo stuff. my car is not immo defeated yw about the turbo stuff tho

We're talking about hardware, if you add software...

Yes, the aww id immo2, while awps and etc are immo3

i learn something new everyday

I have a 2001 Wolfsburg. Question - What does "Wideband" mean? I see this a lot but can't find anything explaining what it is. Thanks.

this applies to your o2 sensors. wideband is better than narrowband. you have a 01 wolfy so you are wideband no worries

It's in reference to the type of front (pre cat) oxygen sensor

For gasoline, the perfect ratio of air to gas is 14.7 to 1. If you are below that number you're running 'rich'. If you're above that number you're running lean.

It's a very important measurement in a fuel injected engine as it is used in the calculation of how much fuel to spray, how much to retard timing, and how much to open the throttle body.

A 'narrowband' sensor has a narrow range of readings. It tells the computer, "I'm rich" or it tells the computer "I'm lean". If the computer wants to run at say, 13 to 1 AFR it will use that plus other measurements in order to estimate the air to fuel ratio. Often, a temperature sensor will be added to narrowband equipped engines in the exhaust manifold (pre turbo) as there is a strong correlation of exhaust gas temperature to calculating the afr for a given engine configuration. Also, narrowband sensors output generally 0-1 volts, in a digital style output ( high or low)

Narrowband sensors have been around a long time (~35 years)

Wideband sensors have only been around since the mid 90s. They output the air to fuel ratio directly. No multiple sensors. No weird calculations. They react fast and are accurate. Awesome technology, thank you Bosch! They generally output 0-5 Volts with an analog style output
