Hi folks

Hope your are all doing well.

I got a trouble with this 350z from Japan. Impossible to read by obd ! Nisprog, KESS3 .etc.. impossible.

I read it i jtag with KESS3, but now, can't find a compatible ori file nor a working definition file

Can someone please check in the file ? If you have the original file corresponding it will be very cool if you can share it with me (the car is already tuned, but i want it to be back to ori to make the tune myself)

Can someone also help me to have a working definition file ?
Tried all XDF from github repo, but always got : can't load, unexpected error

EDIT : The strange part is that if i flash the qrcode on the ecu, it give me that it's a CD700, and not a CF710. Car is running, not that well, but could it be a wrong file uploaded on the ecu by the revious owner ?

Thank you very much

This .bin is called 1CF170 and it seems to have the wrong K value or is configured for E85. Special injectors can be installed on the engine. Be careful when replacing K. Get the original .bin here viewtopic.php?f=64&t=19445

I write this SW to the test ECU on the bench by OBDII.
Then i read back the same by OBDII without any problem.
Don't know why you are can not read it by OBDII.
