Louis,

I spent quite a bit of time looking at this during Feb/March. As I recall both Zdyne and Hondata had a solution for your car and in both cases it was pricey. Zdyne will work for the CRX at least based on my conversations with them over the phone.
As I recall, the advantages of these systems are you can program them yourself and test if you have access to a dyno. Both have extensive websites.

I am not aware of anyone else.
