i have a 90 crx hf that has a ecu pm8 this guy said that he would sell me a pm6 i guess thats the si from what he said and it should run better and stronger now im stock will this mess my car up in any way or is he not knowing what hes talking about help please! thank in advance

 

don't do it. leave your ecu in there. you'll just waste gas, and still don't go anywhere best bet is a swap, and use the ecu intended for that motor

 

cool man thanks for your advice!
