Question regarding my tune and emissions passability...

[scttydb411]

from what you've said you won't pass.

when i tune i shoot to keep the fuel trims low and close to stoich just in case the o2 doesn't work when it's re-enabled you'll at least get good economy in the lower load areas. even if it's flat 14.7 w/o a cat it'll fail most of the time. you should re-install the cat and re-enable the o2. the cat will clean up the emissions and the o2 will average out flipping back in forth rich/lean. it may possibly pass w/o the o2 and a cat, but based on you saying while cruising you're smelling fuel and not the best mileage i doubt it.

thanks for clarifying!
