Default Tuning tips for emission test

I am trying to at least get close to my emission limit for my test.

I have done some work already, but mainly adding the cats made a huge difference.

What can I change in my program to help with the e-test numbers? Fuel, timing???????

Thanks,

Roman

less timing will help HC. Try to get the A/F as close to 14.7 as you can

Ok so retard the timing a few degrees and pull out some fuel too.

That was simple.

Anything else?

hard to say without knowing what your test limits are, and what your car is like.
