Professional VP44 Diesel Fuel Injection Pump Tester and EDC Simulator for 4/6 Cylinders

The VP44 Tester is a high-precision electronic diagnostic tool specifically engineered for the testing and calibration of Bosch VP44 electronic fuel injection pumps. This advanced simulator replicates the engine control unit (ECU) signals, allowing technicians to evaluate pump performance without a vehicle. It supports both 4-cylinder and 6-cylinder pump types, with a user-friendly interface to adjust critical drive parameters such as PWM duty cycle and cam speed. Designed for professional diesel workshops, the VP44 tester enables comprehensive diagnostics of zero-load, start-up, optimal efficiency, and maximum fuel delivery stages, ensuring every pump is restored to original factory specifications.

Professional VP44 Diesel Fuel Injection Pump Tester and EDC Simulator for 4/6 Cylinders Advantage

Dual Configuration Support: Easily switch between 4-cylinder and 6-cylinder modes with a simple rotary button short press.
Precision PWM Control: Features adjustable PWM duty cycle (0-100%) via a rotary knob or direct touch-screen input for accurate fuel delivery simulation.
Comprehensive Test Stages: Pre-programmed with standard test steps including Zero Oil, Start, Optimal Efficiency, and Max Oil Quantity.
Multi-Language Interface: Built-in support for English, Russian, and Chinese, making it accessible for global diesel service centers.
Advanced Parameter Customization: Allows technicians to set lifting current time, hold current duty cycle, and protection current (mA) for deep-level diagnostics.
Real-Time Data Monitoring: Displays cam speed, PWM percentage, and actual oil quantity on a high-clearance digital screen.
High Safety Standards: Integrated protection current settings (up to 15,000 mA) to prevent damage to the pump's electronic control unit during testing.
