    Chrome and nbo2s

    I know you can disable one or both nbo2s in chrome. If I disable the front, running off just the rear, does that set both front and rear trims off the rear nbo2, or does it stay locked at the prior nbo2 trim setting?

    Sets both to rear. IIRC even without chrome the rear sensor is primary so just unplugging the front will set both banks to trim to rear sensor, but it sets a CEL. I did this back when I ran the MAFT-Pro and used the wideband's narrow output and plugged it into the rear sensor wiring. I chose the rear because the rear bank seems to run leaner (4 and 6 specifically) on most 3s's.

    There is no logical reason to disable one of the NB sensors....

    I've tried everything to get my front trim to stabilize. New nbo2, checked wiring, stock injectors, new 550cc injectors, swapping back injectors to front,swapping nbo2s from front to back. Front just will not stabilize. Don't have any exhaust leaks either.

    I'll have to go back to my logs, but I don't recall it doing much of anything. Mid would move a little depending on where the stft front would decide to do
