Im fine now and have learned that some things can be tuned in normal closed loop. Honestly i just watch the graphs and so far have not have too many issues. For me, startup....warmup and idle was the toughest. Cruise and WOT was not too tough to figure out. Seriously, all I did in some cases was to watch my torque and trims. If I saw a trend after a change, good or bad I adjusted accordingly. Usually in closed loop. I'm fine with open loop tuning but have proven it to myself that some things can be tuned in closed loop. After all that's how its driven.Open loop tuning does take a LOT less time of course, but I'm not running a shop.
