I have been fighting a lean instance from around 4800 and up.
I did a couple logs today and this is what I found.
The injectors are hitting 16.32 m/s at 4800 and staying there thru to red-line [100% maybe?].
I am not familiar with vag-com in fact today was the first day doing anything other than a TB alignment or code clear. the car has had this issue with 2 ECUs now.Here is the rundown.

at 6520 rpm
Maf= 179.17 g/s [close i think but i have a 3 inch housing so ??]
injectors= 16.32 m/s [from 4800 to 6800 rpms]
timing= -17.3 to -19.5 [should I also pull near -30* under normal driving]
O2= 0%
Now the only thing that looks weird to me is that the O2 is staying at 0% while it is runnin lean??? But like i said I am not familiar with Vag-Com so it may be correct.
Any help is greatly appreciated.Man do I need it http://****************.com/smile/emthup.gif

The car has a 99 Audi A4 AEB 1.8T with 3inch maf housing,T3,brand new 440cc from Scott and three inch exhaust.

Re: What do you think?? [vag-com content] (DubGray1.8T)

can you post all the data that you have in your spreadsheet instead of the graph. Looks a little confusing on there.
MAF data seems kind of low. I know that the 3" housing will affect the values somehow but 179 seems low.

Re: What do you think?? [vag-com content] (chaugner)

Like this?
this is the raw data and the only other info I have. Thanks for responding by the way
http://****************.com/smile/emthup.gif You can just save it to note pad and put it in vag scope yourself.. The two spikes are 2nd and third to rev limiter.

Re: What do you think?? [vag-com content] (DubGray1.8T)

You would think in the worlds largest VW and Audi enthusiast site some might have some input. seriously can anyone tell me if the MAF,timing and or O2 look normal. I am starting to think this is the MK4 forum.

It looks like your car is going to blow up at any moment.
Just kidding. 179 is a little low otherwise looks good.

thanks to Dave and you. LOL. but what are the injectors doing at 16 m/s from 4800 to 6800?? i am unsure as to what m/s at 100% duty cycle is?? anyone know.

Re: What do you think?? [vag-com content] (DubGray1.8T)

since you are worried about timing, MAf and o2 try the following.
003 - MAF, Throttle Body, Timing
020 - Timing retard on all 4 cylinders
115 - requested/actual boost (not sure if you clamp)
Put up graphs (excel not vag scope) of each one individually.
MAF
Throttle Body
Timing
Requested/Actual Boost
There are 2 others (I think 31/32) that allow you to log the O2 sensors to find out if they are wrong.
Injector Duty Cycle. Not sure how that will work since you have different injector size and fuel pressure then stock.
http://forums.vwvortex.com/zerothread?id=1378654
Not sure if that link will help.
Its hard to help out if you have to read the vag scope graph since its not easy to see whats going on. The data you pasted cannot easily be imported into excel for viewing.

Re: What do you think?? [vag-com content] (chaugner)

Re: What do you think?? [vag-com content] (DubGray1.8T)

thanks. and what are the units for the injectors? m/s looks like meters per second...should it be ml/s or cc/s ?

Re: What do you think?? [vag-com content] (DubGray1.8T)

ms = milliseconds of injector on time
3" MAF and 440 cc injectors
Is that 440 cc/min at 3-bar?
What is the stock MAF size and stock injector flow rate (volume at a rated pressure)?
When running open loop O2 correction will show 0 (no O2 feedback correction).

Re: What do you think?? [vag-com content] (john s)

yes the 440s are being run at 3 bar.
The stock Maf size is 2 3/4 ish and injectors are 210cc at 4 bar.
also do you think pulling -30* timing is strange.

30° bTDC is not unusual at part-throttle
You need to do a new run, use the tallest gear you can and run WOT from the lowest speed you can right to the rev limiter (don't row through the gears).
