AT-133 - Dynojet Power Vision 4 Autotune Kit with Bungs Harley-Davidson (ECU G26 / MT22)

The Dynojet AT-133 Autotune kit is an advanced calibration module designed to integrate directly with the Power Vision 4 (PV4) device on Harley-Davidson motorcycles equipped with new generation G26 and MT22 ECUs.

Unlike stock narrowband O2 sensors, the AT-133 utilizes Bosch wideband lambda sensors capable of measuring the true Air/Fuel Ratio (AFR) with extreme precision across the entire RPM range, from idle to full load.

The system analyzes data in real time and automatically corrects and refines the Volumetric Efficiency (VE) tables via the Power Vision 4 ecosystem. This ensures optimal performance, immediate throttle response, reduced operating temperatures, and smooth power delivery, adapting the fuel map to any mechanical modifications (aftermarket exhausts, high-flow air filters, cams) or weather and elevation changes.

Key Features

• Real-Time Tuning: Continuously measures AFR values, sending live data to Power Vision 4 for automatic map correction.
• Bosch Wideband Lambda Sensors: Full-spectrum air/fuel measurement for precision unreachable with stock sensors.
• Automatic Optimization: Eliminates the need for expensive dyno sessions after installing new performance parts.
• M18x1.5mm Bungs Included: Supplied to be welded onto exhaust headers at the optimal position for wideband sensors.
• Seamless PV4 Integration: Direct communication with Dynojet Power Core software and the Power Vision 4 mobile app.

Package Contents

• Dynojet AT-133 controller module
• 2x Bosch Wideband Lambda sensors
• 2x Weld-in steel bungs (M18 x 1.5 mm thread)
• CANBUS and power connection harness

Note: Requires the Dynojet Power Vision 4 device to write and flash maps. Included M18x1.5mm bungs must be welded into exhaust pipes at a minimum 10° upward angle to prevent moisture accumulation on O2 sensors.
