making a smog tune
I need to re-register my car (1987 acura integra running dsm 450s and turboEdit), and to do so, I need to do a smog check.
With a quick search, I found out that leaning out the fuel makes my NOx go through the roof (damn), so I need a lil advice on what I need to do so I can pass smog.
Am I just aiming for 14.7 afrs and stock timing? Will chanigng the timing help/hurt my chances of failing the smog test? Does it matter if I am in open or closed loop?
any advice would be helpful.
thanx.

Re: making a smog tune
putting it back to stock probably is the best option, but, it would be cool to have a smog tune use. That way I can stay lazy, take 2 mins to burn a new chip, and pass the test.
well, if nobody knows any tips to tune for smog, then going back to stock will have to do.
