    They have completly different fuel and ignition maps on them, even though it would plug into your harness. Also i do believe that the prelude uses peak and hold injectors that have a resistor box while your integra uses saturated injectors which dont have a resistor box and work totally differently. Chances are trying to use that ecu is just going to damage your engine. Just buy another one, they are not that expensive!!
