Data Logging VCDS

I finally will have a weekend to Data Log my EPL 93 and 104 tune, but want to know what you guys are recording. I noticed there are redundant lines for what seem to be the same thing. So I need the Loc # for what I need to data log using VCDS.

Contact Chris at EPL. This is what he told me for my '17 3.0T Q5 with Stage 2 93 octane tune:

For logging you want to make sure that you select Group UDS and turbo before starting and do a 3rd gear full WOT pull to the 4th gear change and log for

Group 15 - Field 0 Vehicle speed
Group 25 - Field 0 Engine speed
Group 216 - Field 0 IGA_AD_1_KNK[0]
Group 222 - Field 0 Ignition angle; actual
Group 233 - Field 0 Lambda probes actual; bank1
Group 345 - Field 0 Air mass
Group 352 - Field 0 Intake manifold pressure
Group 556 - Field 0 Intake air temperature
Group 623 - Field 0 Charge air pressure specified value
Group 625 - Field 0 RFP_AV

So for a 3rd gear pull you start at the lower RPM range in 3rd gear then run it out to the 4th gear change correct? I haven't logged in like 10yrs
