Turbo and passing smog

By couch_c
- Mon Sep 03, 2012 2:55 am #314854 Wondering if there is a way around this, having a turbo without a carb legal sticker will not get you to pass smog legally, i even heard w/carb number it's difficult to pass. How do I get around this?

I was actually thinking (since I'm going low psi) keep my stock injectors, stock fuel pump, stock everything but the turbo, keep a spare ecu that way when it's time for smog i can just remove everything and throw back on the old ecu, but i wonder if that'll work.

- Mon Sep 03, 2012 4:58 pm #314883 just an idea, but why not run dual program on the ecu. run your boost level whenever then when you are going for smog check, run 0psi and a lightly lean tune, but no too lean to cause damage, so you should pass.

not making boost at 15 or 25mph.
most tunes are way to rich however.

i'm was assuming you are running decent boost and larger injectors. if not then an open wastegate and stop ECU works.

or like a said a boost tune and a stock tune on a chipped ECU

the inspector might check under the hood and most will not pass cars with any mods. unless you know someone like mentioned before. so the dual tune might not be the best

exactly what i was saying, so I'm guessing my idea will probably work, I just want a little more torque, not trying to upgrade fuel injectors or do any engine mods, just low psi, that way I can keep my stock parts and when smog time comes, remove the turbo and put back the exhaust and throw back on the original ecu
