Dynojet Target Tune For Harley V-Rod If you already have a Dynojet Power Vision installed on your Harley, but you're looking for the next level in performance, you need a Target Tune to convert your bike to a closed loop system. The Target Tune utilizes wide-band sensors to constantly optimize the air/fuel ration of your machine. It is capable of reading all necessary components (air flow, amount of fuel, temperature, and more) and in real time. No longer do you need to worry about bogging down when going through the mountains, or power loss when you see those extreme heat days. Target Tune is constantly monitoring your bike's performance and making adjustments to optimize performance. Features: Allows the factory ECM to interpret and use wideband o2 sensor signals Target fuel table from the calibration is achieved in real time Retains OEM closed loop and achieves adaptive fuel control strategy Learns and uses VE table corrections as you ride Does not interfere with dealer diagnostic/ service tools Includes OEM style connectors to plug into factory o2 harness, either 2 or 4 pin versions Options: With O2 Sensors: Includes O2 sensors and Y-adapters. This is correct for most users. Without O2 Sensors: option is intended for users that are upgrading from Power Vision Auto Tune to Power Vision Target Tune. These users should already have wideband O2 sensor hardware and Y-adapters installed from the previously installed Power Vision Auto Tune kit.
