HKS Japan often said that HKS reflash for S/C outside Japan is not possible on non Japan ECU.
I know that HKS Flasher for S/C writer operates only for Japanese car and it needs:
#1. ECU FW with a genuine .pak file of JDM;
#2. HKS flasher chechs if VIN and ROM are JDM;
#3. If a rewrite is almost done on a genuine ECU, HKS will not reflash.
#4. No reflash is done on an override ECU with other tune.
I know that EDM and USDM later grade maight not be fully interchangeable thus is there a different management of Baro and MAF due to US emissions rules.
My question is:
#A - If I get SSMIII (and J2534) updated which contents include all Subaru's .pak file (JDM, EK, AE and so on), can I flash an EDM ECU with a JDM pak file (you need to change VIN with a Japanese one)?
#B - after that, the JDM reflash grants me the choice to use HKS flasher to tune my S/C;
#C - JMD ECU management might be adverse in NBC or other modules?

As far as I know all ecu hardware is same just the ecu calibration (tune) is different for each country and the VIN changes with each car.
I have had people put A01G roms in Japanese cars ie A00A for example and it works fine, just did another one couple of days ago ,was Japanese import t Australia.
So you will be able to flash a say A01A Japanese rom to your A01G car and it will most likely work fine unless their is some external changes like emissons . as long as the hks editior will allow you to disable codes it should be ok. however their tune is likely locked ??
you could also change the VIN this does not effect ability to start car only effect licienced tools like ecutek hks and brzedit OFT.
I would thik you would loose your ecutek licience if you overwrite with hks editor tool.
the safest option might be to purchase an ecu and test on the second ecu. and keep your original ecu to swap back in in case of problems.
