ok, im doing the conversion and I am getting the harness already. What I am confused about is the ecu. I see lots of OBD1 prelude, gsr and si ecu's for sale. Can I only use the gsr one or will a civic one work? Whats best to use?

 

ok, well we have no idea what motor you have? or even car for that matter of fact.

 

97 gsr

 

so with a p28 my secondaries wont open? in what ways would it affect my car? make it a lil slower?
