Do a Region capture of your screen w/only the salient bits, then save it as a medium resolution jpeg file.

Viola! Post ahoy!

Save it as a jpg file. Don't forget you need to let us know what gas and mods you run as well as the procede settings

I just want to know if this datalog is showing any signs of knock or cutting timing...? I may need to raise Ign. Correction to 80%

Timing curves look great!

Steady upward timing advance as rpms increase with no sharp dips at all....so no knock

Noticed some throttle closure as you got near the gear shift.....but that could be the Procede controlling boost pressure as you neared the shift point.

Timing looks good!

Lower IC to 60% and see what happens...
