Melo89Crx

Hey everyone, well I have a 89 Crx Si. I did the swap, the engine came out of a 91 integra. B18A1. Everything is set and ready, I turn the engine on like 2/3 times. it seems like the engine is not burning the gas good. The engine was rebuilt so I know the engine shouldnt smoke. U got the integra ECU, all my vaccum lines are check. But my question is do I need the OBD0 to OBD1 jumper harness?? Im not sure cause the integra is 91 and they are OBD0. Do I need one? If so what kind?
Thanks
