R25ECU

rsk@katakurarsk.com · August 1

I have a question.

I am attempting to flash the ECU on my Yamaha R25 (part number 1WD-H591A-00) after a long break.

I have connected the 4P-08 bench harness and am trying to perform the flash, but I am unable to write data to the ECU.

Do you have any idea where the problem might lie?

Incidentally, I have another ECU with the same part number, but I get the same result with it as well.

I have uploaded some images that might be helpful. they are arranged in order from the bottom up.

Please let me know if anything is unclear.

Thanks.
