Hi

I have a 2004 Honda Civic DX Automatic

and I recent JDM swap. I installed an D17 with the matching transmission from Japan. Then I bought a JDM ECU for the EX it's the 37820-PSA-J83

I also installed an EX harness from a 2004, I had gotten even thing plugged in. She will start but won't fully run. I just get the Key light blinking, I took it to my local locksmith he was able to program the ECU he was able to connect to it but he said the immobilizer possibly isn't taking the changes, or I have a bad ECU, which I bought from eBay so that is possible. Any other ideas? I know Hondata isn't for A/T but there has to be another way. I basically have all the parts from a JDM car.
