Then I open the ZA1JA00C rom. It says the checksum needs to be corrected. My understanding is that correcting this then flashing is what bricked Skullworks's car.

Questions then.

Can I flash the ZA1JA00C rom?
Should I modify the definitions file in some way to get the ZA1JA01C rom to flash? I believe they're the same ROM with a slightly different name. Or perhaps I'm adding the wrong ecu defs somehow. I don't think I am, though.
Should I fix the checksum? My understanding is a big NO.

Thanks! My intention is to make a guide for this to make it easier for others.
