Hi Steve,
Just wanted to get your opinion on my issue.
You recently tuned my RX7 back in Feb '12 in San Jose, CA and I wanted to know if the tuning has any effect of my car failing my smog test this week.
I have an Apexi Power FC, can adjustments be made with this?

Here is the failed reading:

NO (PPM)
Max=704
Ave=194
Measured=1074 - FAIL

Let me know what to check for.
Thanks,
AL

Do you have the airpump working? it's almost impossible to pass smog w/o the air pump. I would change the spark plugs and run some alcohol in your fuel to help with NOx
