The one that makes it run? I would go with the OBD2 but you may need to get Hondata to put one together for you.

run an OBD2 Gsr ECU

:smokin: definately OBD 2, but you MUST have it programmed to your combo or you will risk engine damage. Hondata is a safe bet, and they also make a wide variety of ECU's that are programmable on the fly so that a plus

old thread, let it die.
