Im in Texas. I will check into the obd scan. So, i can run the jdm ecu with my dash harness. The obd2 scanner will not work. If i need to.scan the ecu i will have to connect directly to it. If my state does check the engine year info when getting an inspection i can just unhook the jdm ecu and replace it with my usdm ecu. There shouldn't be any issues, just that my avcs will not work.
