At Badger5, we have invested in the industry-leading ASNU Classic GDI Injector Diagnostic Testing & Servicing System to ensure our customers receive the most accurate, safe and detailed injector analysis available.

Modern direct injection engines demand far more from their fuel systems than ever before. If you run a vehicle with Gasoline Direct Injection (GDI) – also known as:

Fuel Stratified Injection (FSI) – VW / Audi

Smart Charge Injection (SCi) – Ford

High Precision Injection (HPI) – BMW

Charged Gasoline Injection (CGI) – Mercedes-Benz

Direct Injection Spark Ignition (DISI) – Ford / Mazda

— then precise injector performance is critical to power, economy and emissions.

Why Injector Testing Matters More Than Ever

Unlike older manifold injection systems, GDI injectors operate at extremely high pressures – often between 75 and 200 bar – injecting fuel directly into the combustion chamber in milliseconds.

Modern engine management systems can adjust fuel trims by up to 15%, but here’s the important part:

Fuel trims compensate for a problem — they do not fix poor spray distribution or atomisation.

No current ECU can measure or correct faulty spray patterns. That means uneven fuel distribution can still cause:

• Loss of power
• Poor fuel economy
• Rough idle
• Increased emissions
• Long-term engine damage

To truly diagnose the issue, the injectors must be removed and properly tested on specialist equipment.

The Badger5 Advantage

With our ASNU Classic GDI system, we can:

Simulate Real Engine Conditions

• Sequential and simultaneous firing modes
• ECU-matched peak and hold current control
• 18 programmed millisecond and RPM test settings
• Static and dynamic operation testing

This means we replicate real on-car spray patterns and flow rates — safely and accurately.

Test Up To 8 Injectors at Once

We can compare injectors directly against each other, identifying inconsistencies in:

• Spray pattern
• Atomisation
• Flow rate
• Electrical inductance
• Opening and closing response

This comparative testing is essential for performance and tuning applications.

Safe & Controlled High-Pressure Simulation

While GDI systems can run at dangerously high pressures on the vehicle, our ASNU system allows safe testing at controlled pressures (up to 10 bar) while still accurately simulating ECU behaviour.

This enables detailed visual analysis without risk.

Professional Ultrasonic Cleaning

Our system includes a built-in ultrasonic cleaning bath with manual and automatic cleaning cycles, helping restore injectors where possible and ensuring:

• Improved spray consistency
• Better atomisation
• Restored performance

Suitable for Multiple Applications

Our system supports:

• All manifold injectors
• Most GDI / FSI injectors (excluding piezo unless specified)
• Motorcycles
• Marine engines
• LPG injection systems

Why Customers Trust Badger5

We didn’t invest in this system to “check a box.”
We invested in it because accurate injector diagnosis prevents unnecessary part replacement, saves customers money, and ensures engines perform exactly as intended.

Whether you are experiencing running issues, preparing for performance tuning, or simply want peace of mind, Badger5 offers:

• Detailed injector performance reports
• Before and after spray analysis
• Honest advice on serviceability
• Precision testing using industry-leading equipment
