As far as I have been able to tell, the 'tap method' just changes between the different profiles already loaded into the charger. If you get a non-zero 96v QuiQ, they come with PbA profiles loaded by default and will almost surely not do what you want. You need the programmer and profiles to change it.
The part number that Zero uses is unique, so I've made sure that I always get ones that were originally from Zero to avoid that problem. They also come with the right connectors, not that they would be difficult to crimp on. Watch ebay, they come up every so often for a reasonable price; I just sold 3 of mine.
Previous discussions stated that algo '123' was what Zero was previously programming.
http://electricmotorcycleforum.com/boards/index.php?topic=2836.0Most of my charging up until recently has been with the onboard and 1,2,3, or 4 QuiQ. The more current you can push from outside the bike, the better for the temperature of the pack to not have it cooking on the onboard.
