your going to need a OBD1 ECU man. I have a GSR OBD1 p72. I bought this ECU like a dumb newbie not knowing I was going to hondata the motor sooner or later. This ECU is wanted buy allot and it really pricey. The Hondata, Boosted ECU of choice by most is the p28 (Civic, VTEC ECU). Really cheap ECU and it gets the job done with a Hondata. If I had to do it again I would have got this ECU...it's cheaper and does everything my p72 does. Jan is right though hondata site has lots of info. Good luck
