Closed loop lambda control.

Hi- After watching the webinar on G4+ closed loop lambda control i thought id have a go and turn the function on . Id set up a table a while ago but never tried it . Anyway - i enter closed loop lambda mode - click on lambda mode and there is no option for Auto mode- wide band . The only options are OFF - Stoich NB and Stoich WB . The version im running is 5.5.3. Does this matter ? If i update the firmware will it change anything in my tune ? Forgot to add -i have a ecotrons ALM wired in via can . -----

Just read the same question in Webinar questions . Its locked out on Atom . So -can it be unlocked ?

No, This option isn't available on the Atom at all just now
