WHAT IS ECU FLASH IN YAMAHA FZ09 SERIAL

Don't know Woolich if they are getting it right these days great, but get the word out for God's sakes. Most maps are based on it and older versions of the Yamaha ECU firmware.

2018 MT-09 with Akrapovic Titanium alloy exhaust with Carbon fiber cannister. Not only did going back to the stock mapping give me back all my horsepower and torque the popping was reduced as well. My main point is do not reflash without knowing and riding the bike with a new full exhaust first. If the electrode insulators or a light cocoa color. Run it and check your plugs after 100 miles. If you are so concerned about leaning conditions. Do NOT send your ECU in for a tune without first testing if with the stock ecu first. I don’t care if you spend all day on the dyno the exhaust sniffer will read lean when it is not.īOTTOM LINE. The old firmware (pre2017) allowed FlashTune software to turn off AIS (Air Injection System). If you take your bike to the dyno guy and he doesn’t know this bike well and doesn’t ask if you have added the AIS block-off kit.

If your ECU serial # ends in -10 DO NOT REFLASH ECU when you add a FULL EXHAUST from some outfit using maps developed for the old pre-2017 firmware. However, the Yamaha engineers fixed those issues starting with the release of the 2017 models, MT/MT 07,09,10. Those improvements were indeed spectacular because Yamaha’s stock mapping was poorly implemented in many ways. The system is lean already and adding the exhaust will lean it further so naturally we send off the ECU to a bunch of tuner heads that have been improving FZ/EuroMTs since 2014. Put on a full Akrapovic and thought like most of you send off the ECU to be flashed.
