With FG Galletto V54 I have the OBD+BDM+Tricore for how to operate on every control unit to load a ori, but we at the end we load a part of the whole software.
The ecu is loaded with a bootloader, firmware and to finish the maps, then data inside it, there are a lot more to adjust parameters.
Using the socket ODB on the ecu I saw that, I read the data, I have not tried to upload, but it surely does.
On a unit identical to the one I tried to BDM by connecting the various pins in the way intended, however, behaves in the same way that go to the serial port.
Then it remains for Tricore the last beach to be able to make a backup of the ECU, the Flash memory and the Firmware, someone knows the pin inside the ecu, what are they?
I would like to make a clone of the original, modified, maintaining the code, the kmt paths and all the rest...
