I'm having problems with my high milage bike (100K miles). I think it could be the ecu so I bought a 49 state ecu thinking it would be no issue. The bike has the o2 sensors bypass and a DJ PC3. When I swap the 49 state ecu into my CA harness it doesnt see the map sensor. I'm wondering if I got a bad ecu off ebay. Has anyone had any issues swapping ecu's but not the harness?
