Dynojet O2 Optimizer -T4 for Yamaha XTZ1200 Super Tenere (12-20)

To get a motorcycle to run properly in the closed loop area, the area where the lambda sensor is active, it is necessary to disconnect the lambda sensor when the bike is to be trimmed, or to have it included as an active player. Otherwise, the lambda sensor will constantly ask the engine management to provide less fuel. The O2 optimizer here can be used as a stand-alone unit that changes the value that the lambda sensor sends to the ECU. The value is changed from an AFR value of 14.7:1 to somewhere between 13.8 and 14.0:1. It doesn't sound like much, but it is enough to make many motorcycles run noticeably better, without putting them on the road. The O2 optimizer can also be used in conjunction with a Powercommander. Check under vehicle fitment to make sure you get the correct one. NOTE regarding use: Please note that manipulation with the O2 sensor is not legal on public roads, which is why Pitboxen only sells this product for use in motorsport on closed track facilities.
