Flash V1.2 System

The KTuner Flash V1.2 System is a flash-based tuning solution engineered for 2008-2012 Honda Accord 4-cylinder models, including LX, LX-P, LX-S, EX, and EX-L trims, as well as PZEV variants with either automatic or manual transmissions. This system allows for direct ECU reprogramming via the OBD2 diagnostic port, simplifying the tuning process without requiring ECU removal. It offers a comprehensive suite of tuning capabilities, including real-time logging, ignition and fuel tuning, VTC tuning, knock tuning, throttle control maps, rev limiter adjustments, 2-step settings, and VTEC window control. The KTuner software also provides the ability to disable sensors and OBD2 monitors, and it removes the speed limiter, though this feature is intended for off-road use only. A laptop running Windows XP or newer and an internet connection are required for registration and use. While the KTuner Flash system aims to maintain factory drivability, emissions, and reliability, it is crucial to note that **THIS PRODUCT IS FOR OFF-ROAD MOTORSPORT/COMPETITION RACING USE ONLY, NEVER TO BE USED ON ANY POLLUTION CONTROLLED MOTOR VEHICLE.** The manufacturer advises flashing the vehicle back to factory settings before driving on public roads. Dyno testing results show potential gains, with one test demonstrating +15hp and +13tq with specific modifications and tuning, and another showing +17tq and +13hp with an intake and tuning. The system is compatible with specific ECU part numbers within the 2008-2012 model years. No aftermarket wideband O2 sensor is required, as the factory sensor performs adequately for tuning.
