Hello!
I have this plastic ECU and I want to help to find how you can flash it. I've found the specs:
Datasheet: http://www.xtreme3s.net/H8500/H8%20539F.pdf
Prog guide: http://other.ditcorp.com/legend/programming.pdf
I also learned about the 0 page restriction and vector table cloning to page 1, but I'm still having a lot of things I don't understand, and I'm trying to learn.
Is anyone else trying to find a way to flash this ECU. Does anyone know where I can find more information about this ECU?
