jdm vs usdm ecu

I'm sure there is a thread out there but I cannot find it.

I have a jdm and a usdm ecu for a s6 car. What is different about them? Pinned different, different size injectors? Knock sensor timing? Ghosts?

They are pinned different , and they do not have EGR . there is a thread I used myself a long time ago that dictates those differences in the pinning , Infact someone brought it up not to long ago .

the differences are the same as the Power FC, the JDM ECU does not have EGR, AWS, two of the solenoids on the ACV or the E/L box

other than those differences it does use the same hardware (injectors, engine, etc), and seems to run the same
