Jdm ecu
We did a swap in an 03 civic ex with an k series type r motor. we had it running great with a type s ecu, we used the honda HDS to program the key to it. we now have the jdm computer that we were supposed to get. The immobilizer light is now flashing and The honda HDS will not let us program the Key, it dose not communicate with the ECU. I have read the JDM ECU dose not have an immobilizer. if that is the case why is the key light flashing. If anybody knows how to get this ecu to work properly can you please help me out Thanks.
