and all codes were for bank 1 sensor 2 voltage low input. and bank 1&2 both sensor 1's were stuck rich.
then you should contact AA. i also have AA tune and was thinking of getting the off road version but after talking to karl, he did not guarantee it will turn off all the O2 codes, so i went with the normal tune and got O2 sim from BMS.
