i read the ecu 32920-02H00 and flashed back the orig file but the bike doesnt seem to start now
the faults are c21 c23 and c42 . the bike has always been working fine so i know it cant be a hardware problem and just to make sure i rechecked al lthe sensors relating to the fault codes.
anyways does anyone have an orig file for this ecu so i can compare with mines, i am wondering if i didnt mess up the read...
http://www.sendspace.com/file/kulhlk --- my orig file
Unlike the busa and 1000 which use the 7052F cpu the 600/750 uses the 7054F which has a 384k ROM (h'00000000 - h'0005FFFF). Unfortunately by flashing it with the incomplete bin you have erased the last 128k of the ROM and it will do no good to try to download it now.
ok interesting, do you by any chance have a complete file for a 600/750 02H00 which i can write back ?
also why i thought it was complete is because when i read a 32920-41G20 using the 7054 the remainder of the info was only FFFFF, in my 02H00 file you will see also it is filled with FFF leading me to believe the processor was 7052
anyways silly mistake, hope you or someone has something to help.
what i do have is a 32920-01H00 as well but this ecu doesnt work on the bike its porbably from a 1000 , i coded a key for the bike to this ecu to test.

Actually all Denso bins end with 8 chars of ASCII text in the last 16 bytes (h'0003FFF0 for 7052) that is the bin version id. If you don't see that then you have not read the end of the bin.
If you look at the end of your 41G20 you should see something like 'D47ASE02'
Gotcha if possible i would like to know how you gained ROM from that, i mean pinout or from CPU itself? I am going to start with 02H10 and that would be reaaaaaaaaally usefull to know where to start:)
Well i hoped i could use USB device connected to adequate pins (like 1k)
I think there may be some confusion here.
All older suzuki (k3-k6 GSXR 1000, k4-k7 gsxr 600/750 ) use the SH7052 CPU. The 7052 can be flashed from the wire harness pins but can not be uploaded (READ) from the harness. You need to cut it open and read it from the AUD CPU port.
The new suzuki (k7 gsxr1000, K8 busa, gsxr 600/750) use the m32r CPU which can be read and written from the wire harness pins.
Best would be to find bin file for 600 K6 EU version as mine and start writing definitions, but as i checked nobody has it so far and i would not prefer to open ecu that is in my bike right now... I will try asking companys that flash ecus if they have one of those:)
