Tiberon V6 uses a siemens ecu with a infineon C167-CR microprocessor
The early variant ecu has a 29F400BB, the latter (september 04+) 29F800B.
The ecu flash can only be read via diagnostics with a program uploaded to ram just like the subaru, as the factory code only facilitates programming.
The ecu speaks Kwp2000 protocol on the K-line.
Attached is a read from a tiberon flash for disassembly
