FOXWELL JT200 Fuel Injector Tester, Fix Engine Misfire & Rough Idle - Visualize Spray Pattern & Volume, Automatic Fuel Injection System Tester Diagnostic Tool for 6V/12V MPI Motorcycle & Car Injectors

• 【Stop Guessing, Start Saving - Find the Faulty Injector in Minutes】Tired of throwing money at new injectors only to find the problem one? The JT200 enables you to visually compare injector spray patterns and injection volume side-by-side, helping you quickly identify issues such as blockages, leaks, damage, or burnout of the injectors. No more guessing which one is weak or clogged. As one mechanic put it, "This tool pays for itself after the first job. It saves you time and money by preventing you from putting a weak injector back into your engine."
• 【See the Problem - Clear Spray Pattern Visualization】A faulty injector doesn't always trigger a code. Often, it shows up as an uneven spray pattern or poor atomization. The JT200's transparent tubes give you a clear, unobstructed view of the spray pattern and atomization. As a repair technician noted, "This is a significant improvement over traditional tools that only test continuity. It makes it way easier to spot a weak one without swapping out parts blindly."
• 【Precision You Can Trust - Measure Injection Volume with Confidence】The JT200 features easy‑to‑read graduated cylinders that let you precisely compare each injector’s fuel volume against manufacturer specs and against each other. The injection volume scale is clear and the readings are intuitive, facilitating quick comparison for injection volume deviations.
• 【Real-World Engine Simulation - From Idle to Redline】Use Automatic Mode to simulate acceleration from idle to high speed, or switch to Manual Mode to pinpoint issues at a specific RPM (100 to 9900 RPM). No need to starting the engine every time, the JT200 powers and tests injectors right on your workbench. The sealed and transparent graduated cylinders prevent high-temperature flammability and enable easy reading.
• 【Wide Compatibility for Cars & Motorcycles】Comes with a full set of Φ9–14.5mm adapters for most traditional EFI injectors, MPI top-feed injectors (Not for GDI injectors). Covers you from the family garage, shop, or DIY. Whether you're working on a 6V motorcycle or a 12V car, the JT200 has you covered. Simply connect to the vehicle's 12V battery and you're ready to test. [Notice]It is recommended to use test fluid. Kerosene or diesel may be used as substitutes, petrol is not advised, as its strong solvent properties may corrode the tubes and it is highly flammable.

Makes Fuel Injector Testing Simple and Safe

Visually compare injector spray patterns and injection volume side-by-side for easy, safe fuel injector testing. Compatible with Φ9–14.5mm injectors, suitable for most 6V&12V gasoline vehicles and motorcycles.

Automatic Engine RPM Simulation Mode

Automatically simulates a full range of engine speeds -from fast to slow -to replicate real driving conditions. The adjustable test duration (30–600 seconds) enables both quick checks and extended tests for enhanced accuracy and reliability. 

 Manual Engine RPM Control Mode

Manually adjust rotational speed in ±50 RPM every 0.5 seconds, covering a wide range from 100 to 9900 RPM, this enables precise testing at any specific speed for advanced troubleshooting.
