Difficulty Passing Emissions on my CRX

[KevinT707]

So after reading the DIY thread on passing emissions numerous times failing 3x now my tag has been expired. I already purchased denatured alcohol and intend on trying it out on the CRX. As it sits with the proper street tune it fails 3/3; when I turned the fuel pressure down (via B&M min. 42 psi min.) it passed 2/3 but would still fail HC (which means it's too 'rich'); It's a little over double the allowed amount on HC. So my question is should I try running the alcohol without modifying the fuel pressure at all 1st? and ALL 32oz. mixed w/ 1/4 tank gas?

I don't know the chemical reaction that happens when using denatured alcohol (make engine run lean/rich?) so that's why I want to be safe. Also running on a high-flow cat, never used O2 and has always passed every year (except this) by turning FPR down all the way.

Suggestions, insights, comments please, thanks!
