I have a few questions. I was looking at the economy tuning sticky in the V8 ls section and was unable for some reason to open the file that EC_tune posted but further down in the thread it talks about what I think is in the attached file. It talks about moving the switching voltage at stoch. from .431volts to a lower number. I looked at my tune file and found "02 rich/lean vs airflow" under fuel, is this where EC_tune adjusted the voltage to lean out the cruise? Also in DFCO, what is "Enable Clutch Transition"? Is it something with the TCC? If so, mine looks to be turned off. The DFCO MAP settings are well below my idle readings. Should I move them closer the my idle reading and if so how close should they be? Thanks for the help.
