Just got my Vag Com

Where can i find a list of channels that i can use to run in the logs for the engine ?

I was on http://www.mjbmotorsport.com/datafaq.html and i tried to use the same numbers they were (034,20,115) but they will not work.

i think the ones i normally log are 003, 020, 031, and 115 (i might be wrong on the 031)

Alright i will try those , im just looking for air fuel ratio and boost really just the needed ones.

i tried to do some of the other stuff that was in http://www.audizine.com/forum/showth...g+dollar+cable

and the values that were in the ecu were not the same as the write up and would not work when i changed them. the only thing i could get to work was the remote windows

If you notice they are coding a B7 in that thread not a B6, but the thread does get the cable to work.

oh ok, well do u know where i can find the codes to change the rest of the things in the thread for a b6 ?

I know the ross tech website teaches you how the coding is done, but I haven't been able to come up with any step by step instructions yet. I did my seat belt chime off of the ross tech instructions and it worked.

ok so other then scanning and changing some of those codes
what else can u use this thing for ?

Can i reprogram the ecu a/f stuff ?

it's a diagnostic tool.

maybe i should ask, what did you expect it to do?

**03 silverbullet** · 12-19-2008 11:10 AM

i was not sure what all it could do really

I found i can use limmiwinks to do what i want, tune the fuel and timing.

I guess i can use this for logging a/f ratio then

I was originally planing on getting an STI but ran across this A4 first at 2,500 under the " worst " conditions for Kelly blue book and bought it. Car looks great they had it on there lot for 4 months and wanted it gone.

So anyways the EVO and STI crowed is using OPEN ECU for the logging and tuning, since i am not familiar with the A4 i wasnt sure what all i needed to tune it.

VAG Blocks: These are some of the more common ones used

002 Injector time and MAF

003 overall timing and MAF

004 intake air temp and coolant temp

015 mis-fire count cyl 1~3
016 mis-fire count cyl 4~6
20/21 Timing correction (CFs), or “timing retard”
22-24 Timing related data

26/27 Knock Sensor for Cyls 2/5
034 EGT temp bank 1
035 EGT temp bank 2
031 O2 voltage
032 LTFT

114 N75 Duty Cycle

115 Boost (Request and Actual)
120 Torque

Audi doesn't have any software like OPEN ECU, so you can't really "tune" it yourself, for the audi you need to have it done by Revo, APR, GIAC, or Uni. you can tweek it with limmiwinks, but thats about it. I have heard rumors about someone trying to make such an app but nothing ever came of it.

Vagcom is a diag tool used to log and scan. you can change some codes (coding the key FOB to roll the windows up and down, ect), but again, it's not tuning software.
