I'm out there man, thanks to $EEx I'm in OLSD 95% of the time, usually just use CLMAF for startup/warmup and when the motor gets heat soaked and my IAT's skyrocket due to my warm-air induction setup, my SD tune, or lack thereof, doesn't run well with IAT's above ~150f.

My ultimate goal is to be able to get the PCM to do my Lean Cruise stuff without necessarily having to run my laptop and $EEx all the time to do the manual AFR command. I'm thinking that really devoting a lot of time to developing an SD tune to give me what I want, is probably the only way to get to that point, but I'm wondering if it could be done just as well in closed loop, which is arguably easier to tune and has the benefit of the feedback from the O2's
