I'm from the US, and currently ride an SV650 k5 (16 bit MH7203FA cpu). I'm a computer engineer by trade, and have started to disassemble the ECU, and found the tables in IDA. My primary expertise is in Motorola-based ECUs, so these Hitachi/Renesas/Mitsubishi ones are tricky for me. Looking forward to working with everyone, let me know if there's something I can do to help. (and if you have an XML for an SV650 it would be greatly appreciated!)

Thanks,

Fantastic! I have the same bike and am attempting to do the same. I did buy a spare ECU we could run some tests on, but I am still stuck at basic connectivity/communication at the moment. Any information you collect and are willing to share would be greatly appreciated.

Welcome :) :)
