I saw the same add. The only way to legally integrate Hondata into the CRX is to convert to OBD1 and it requires an OBD0 to OBDI harness and an Integra OBD I distributor and crank angle sensor which is obviously illegal.

The other way to go with OBD0,I,II is to the DIY route. I've been working with this for a while. The learning curve is steep though. www.pgmfi.org
