VERY IMPORTANT: Please make sure you are flashing the correct file!

We've been having quite a few instances of customers flashing the wrong file into their Yamaha FZ/MT-07 and ending up with a non-running motorcycle that is showing numerous error codes. You need to double-check to make sure that the file you're going to flash has the exact same part numbers as your ECU; we have multiple files for each year that are for different countries, so don't just see "2018 Yamaha MT-07" and think that it's for your bike. If you flash the wrong file into your ECU, you cause a major write error in the ECU that triggers error codes that don't exist, and you end up with a non-running motorcycle. And unlike other error codes, you can't simply have your dealer reset them.

You will need to "reset" your ECU by flashing our specific reset file into your ECU first, then flashing a new correct file immediately afterward. We will have the reset file available on the server soon, but in the meantime, please post on the forum and we'll email the file to you.

    I have emailed the reset file to you. Please flash that file first before flashing the correct FT file.

    hello, can you please send me a reset file for B34-9591A-10(EU). Cordialement, David

    Hi David,

    There is no reset file for that ECU. Please flash the correct stock ECU image file into the ECU and it should return to normal.

    Hello, I have a B34-8591A-10(EU). I tried flashing the correct stock ECU image file, but my engine trouble warning light turned on and the bike won't start. Is there anything else I can do?
