My stick-level job restored a lot of lost capacity. But since then I've achieved even better results with a DIY grid charger, but probably more importantly, deeper-than-normal discharge. I'm pretty certain just this last cycle I did, where I let the pack discharge by leaving the car in autostop, put it over the top.
Using autostop I was able to discharge the pack quite a bit more than other in-car means, down to 137V, about 17% SOC, and then I used the grid charger to balance charge ('soak' charge, full charge). Whereas before I was only able to discharge the pack in-car down to about 45% with multiple state of charge resets using the OBDIIC&C gauge/controller (and got my first negative recals at about 52-62%), now I was able to take the pack down to 46% without any problems, still get 40-50 amp assists, and the pack rebounded to 150V (at 46% it was down to 147V, but after sitting it came back up to 150V; normally the pack sits at about 158-162V at about 75%, so the fact that it came back up to 150V is probably a good sign)... I could've gone even lower than 46% under normal driving circumstances...
