It seems that the Smart Tune feature in the Screamin Eagle Super Tuner and the V tune in the TTS system use stock O2 sensors while the Power Commander and the Thundermax use wide band sensors for their autotune functions.

Can the wide band systems do a better job? Or are there details that I am missing?
Thanks for any input.
