Did you try LSHHK=11 in ESKONF? (aka HSH)
There were two bit pairs for Rear O2 bank 1 and Rear O2 Bank 2.
Are you saying on top of that there is another one for LSHHK? or is that what this is? you only have mapped 7.1 and 7.5 so im going off piecemeal information off the site.
I guess i can start 11 the sections idk what it is till the car starts... but idk if that will make a difference or why the car wouldnt start if rear O2's arent plugged in.
