It would seem that the Zippers unit should be able to do the same thing that the SERT allows for, in terms of reading the max advance possible before knock sets in, and then backing the timing down by some offset level. It's a solid approach, but not one that necessarily peaks performance.

I do not know enough about the unit to guess.

To find optimal AFR values for peak HP/TQ, you still need a good tuner, no doubt. I purchased the unit because I think the Zipper will out perform most tuners out there without the need to dyno it; certainly in my area. I think any performance gains from a dyno run would be splitting hairs and I would not be able to tell the difference. (IMHO)
To answer your question, yes you can run it open-loop and dyno tune for optimal AFR and timing settings. Once back in close-loop, it will work to keep meet your settings.
