I installed a turbo onto my LQ4, it has a log manifold and i have the drivers o2 sensor in the drivers side manifold and the passenger in the the down pipe of the turbo, i have changed the injector bank select for all injectors to "1" for bank 2. Since i have both o2 sensors installed i still have my STFT working, i am just wondering since i have the injector bank select set to bank 2 is the STFT for bank 2 now controlling all fuel injectors?
