2) Not understanding how you can use BOTH AFC mode and MAF mode -- can you explain?
3) Under "Config" -- "Load Source" should this be set to TPS for using as AFC, or "MAF/RPM".....? See question #2
4) "MAF Sensor / tune" - I have zero frame of reference on this one....what should the values be here?
5) Spark advance option is not availble / compatable with 3S - correct?

Thanks again,
Aaron
1: mainscale shifts the entire tune and is the starting point if you are running oversize injectors. with stock injectors leave it at 0
afterstart is used if you have lean running after you start the engine, most notably when the engine is warm. leave at 0 for now.
leave the load points where they are.

2: there is a value called "UserTune" which is the sum of all your tune settings. If you have a lean spot and you know it always happens at 35 grams/sec airflow, you can add fuel at that point in the MAF page, if you have a rich spot that you know is at 4000 RPM, you can remove fuel there in the tune pages.

3: leave it at MAF/RPM.

4: leave them all at 0 for now

5: not with a Gen-II
