MotorVac 200-1147 Fuel Injection Signal Generator

The MotorVac 200-1147 Fuel Injection Signal Generator is a professional-grade diagnostic tool designed to clean, test, and simulate automotive fuel injector performance with unmatched precision. Engineered for both standard and high-pressure injectors, this versatile device generates adjustable signal pulses, allowing workshops to assess injector functionality by visually observing spray patterns out of the vehicle or by measuring pressure drop during in-vehicle testing.
Featuring a clear LCD display showing RPM, operation time, and status, the 200-1147 simplifies complex injector diagnostics. The dual injector testing capability enables side-by-side spray comparison, making it easy to identify differences in flow patterns, atomization quality, and overall performance between injectors or between a suspect injector and a known good unit.
The adjustable simulated RPM range from 600 to 4000 allows technicians to test injectors at various engine speeds, while programmable working time up to 99 minutes provides flexibility for extended testing and cleaning procedures. The portable, lightweight design with intuitive controls makes the 200-1147 perfect for busy service bays and mobile technicians who need fast, accurate injector diagnostics.
Compatible with both standard low/medium pressure injectors and modern high-pressure direct injection systems, the 200-1147 detects stuck, leaking, and clogged injectors, reducing diagnostic time and improving workshop efficiency. When paired with injector cleaning equipment, it facilitates a complete testing and cleaning process for comprehensive fuel system service.
