Which year is your VE...? (which engine RPO code...? Which PCM/ECM...?)
Which wideband are you using...?
Are you logging from the scantool (V7 software running on laptop) or BBx (FlashScan V2 standalone)...?
What specifically are you planning to do (correct VE, correct MAF, idle tuning, spark tuning, transmission tuning)...?
The maps (histograms) are easy to set up.
The charts are easy to set up.
The pids to log are easy to set up.
(the installed software has a scantool user manual pdf showing how to set up each of those).
This thread contains info you need (and also explains what you need in the calc_pids.txt file relevant to your wideband):
