I'm going to assume they flipped it, as the timing setup in the AEM is catastrophically wrong.
Once it is fixed, they'll likely need to swap it back to normal.
Well, actually I would appreciate it if the car world could get away from using that terrible North American thread form, and use BSP. But yes. Pipe thread all the way.
Point of order - the Japanese do NOT use NPT. Their pipe threads are The Japanese thread form, which is same same to BSP.
Your best and only option is to verify your CAS is reading properly with an oscilloscope (I'm presuming the V2's had a built in one) and then properly sync your ignition and mechanical timing using your offset angle within the ecu. I don't understand why you flipped your CAS.
