    i am trying to figure out what ecu i can put into my 1989 honda prelude si 5 speed to increase rpm and horsepower. someone told me a p28 from a gsr, but to be honest, im new to these cars and im not sure what to do. i circle track race with this car so im not worried about it being street legal. if anyone has a suggestion i would appreciate it. if you could give me the make, model and years the ecu was available in i can start to look for one. the engine in my car is a B20A5. thanks

    The P28 will not work it is an OBD 1 ecu. You have a PRE OBD ecu. wich means the plugs are not even compatible.
