I have seen the other guys on the forum are doing for PowerLab6 settings.

Basically charging the cell to 3.65v, then discharging it at 38amps down to 2.25v while keeping compression on it.

I thought I'd start there.

I would do 3.65 for top voltages for charging but I would not go down to 2.25 volts. No need. No need for clamping either. Clamping will do nothing to save a battery from being over discharged. You will not have bloating issues at 2.25 volts. But if you take it below zero volts and a pretty healthy current you will kill your cell.

I would go to 2.6 volts for the low voltage and I would bottom balance my cells. Remember that some of the cells will bounce up from that low voltage to about 2.7, 2.75 volts resting. If you then discharge it again to the same 2.6 volt you might get it to stay nearer 2.7 volts resting. Then connect all your cells together and charge to 3.5 or 3.6 for your ending voltage. You will be at about 90% full at that point.

I will help with a log profile if you need. Be sure your USB driver is installed correctly so your CellLog 8 will see the computer. If you can't save a change in your profiles then your not talking between the cell log and the computer.

Could also use the CC/CV discharge option ... That is a common method of trying to squeeze out the last of a cycle.

That is how I have mine set. CC/CV for both charge and discharge.

Well, the PowerLab arrived today but got too much on my plate to be able to play with it today. Guess it'll have to wait. Dang.
