Need Tune to Pass Smog Testing in Colorado

[WeathermanShawn]

Hi everyone ~ This is Kristen, Shawn's wife. I am hoping that someone can help me with a tune to pass emissions in Colorado. Tags expire in May; need to get the Camaro to pass emissions so I can re-title and register the car in my name.

If you are familiar with Colorado emissions testing, they put the car on the rollers, put sniffers up to the tail pipes, and hook up to the OBDII connector. They test the car at various speeds, trying to imitate "normal" driving conditions. If I had to guess, they only take it up to 4th gear - it didn't sound like they shifted to 5th at all. (JoeCar suggested I ask them to shift telling them that I normally drive in fifth or sixth - I will do this next time). I've run the car through twice; failed on Hydrocarbons both times; everything else passed.

Shawn has some details on the car setup in his signature (hopefully will show up at the bottom of this post) ... It sure is a lot of fun to drive!

I'm attaching several documents to the post. Both emissions testing results - including trace graphs of the various emissions related criteria v. speed and time. I am also attaching a copy of the current tune. The only difference between the two tests is that I changed the PE modifier in table B3618 from 12.17434 to 14.59447 for all RPM's up thru 6000 for the second test. Hydrocarbons actually increased on that run.

I can run some logs, if necessary, and post them. I'll try to answer any questions I can; I helped Shawn a lot with the tuning initially, then he really took off with it and his knowledge far exceeded mine. I have limited records on the modifications that have been made to the car, but I'll do my best. Any help that anyone can offer would be greatly appreciated!
