I am assuming that to tune with a flash system you would make a logged run on a dyno, look at the logged data, flash and repeat. Anyone want to share their procedure that works for them?

Yes correct for "flash" tuning sequence is, log, Analise results , change,flash ROM, log, Analise change flash ect.
To do true live tuning you would need a different ECU or emulator where some or all of the map tables are stored in RAM so they can be changed on the fly . I believe hydra
http://www.hydraems.com/ can do this to some extent but it costs $$$$$ not really worth it for average person. Probably Motec and other as well.
Saw somewhere here where some Ecutek guys has a pseudo live tuning setup where they hijacked a couple on inputs to the ecu to switch/offset some custom maps on the fly for a sort of live tuning effect.
