Default What PID's to log for initial tuning?

I will be going to our local "1/8th" mile track tonight (really 550ft) to start my tuning... Will be using EFILive and have already done my basic code/ce light/trans tuning... But am new to tuning spark/fuel on ls based vehicles... What PID's should I log to get me started (and to post up to get yall's help)?

Mods include: NGK TR6, MTI Lid, K&N, Smooth Bellows, TB Coolant Bypass, TSP 1-7/8 lt's, TSP O.R.Y., Magnaflow catback, Built Trans, PT4400 converter, full rear suspension, QA1 fronts, Spohn Solid MM's, weight reductions, !A/C, !EGR, !AIR, Bogart's, Skinnies and Nitto 555r 275/50/15 (soon to be 26x10.5x15 ET Drags)...

Do you have FlashScan V1 or FlashScan V2...?

V1: use wideband analog AFR
V2: use wideband analog or serial AFR

Which wideband do you have...?

I am using V2 commercial and do not have a wideband yet... Which I know will make it tougher, but I'm going all motor currently and am just trying to get as close as possible before the heads/cam...

Then log HO2S11 and HO2S21 to get a very rough idea of what is happening.

You really can't do without a wideband AFR sensor.
