FYI - I did a diff of this and my MY04 Wagon ECU dump(
http://forums.openecu.org/viewtopic.php?t=83) and they are 100% identical.
Not too surprising that the sedan and wagon use the same programming, but good to know anyway
FYI - your ECU is AH792 (from the info you have above) just like mine, and your ECU image dump is version A4TF500F (same as mine). You can see that at offset 0x200 in the test_cpu.hex file.
Thanks for posting!
