3 - I read some of the "AccessTUNER_HelpFile_Subaru" manual from COBB tuning. The way it reads, it sounds like the manual is suggesting that you can make modifications to parameters in the MAPs (obviously in RAM, not flash) while the engine is running. Is that the case?
If not it seems like having to reflash for every tiny adjustment would be a huge PITA (not to mention a risk to the ECU having to do it too often).
Am I close?

Your talking about real time tuning and that is a ways off to say the least.
