Why We Need The JT200?
- Engine Misfire? Rough Idle? Poor Fuel Economy?
- Fuel injector problems are often hard to diagnose.
- Without proper testing, mechanics and DIY users may replace parts blindly.
The JT200 lets you see exactly how each injector performs.

Hard Cold Starts
Struggling to start your engine in the morning?
Clogged or weak injectors may fail to deliver the right amount of fuel during cold starts.

Rough or Unstable Idle
Engine shaking or inconsistent RPM at idle?
Uneven fuel injection can cause misfires and unstable engine performance.

Increased Fuel Consumption
Noticing higher fuel usage than usual?
Leaking or inefficient injectors can waste fuel and reduce engine efficiency.

Excessive Emissions
Seeing black smoke or strong exhaust fumes?
Poor atomization leads to incomplete combustion and higher emissions.
Observe the spray pattern of each injector to detect clogging, leakage, or uneven distribution, ensure better combustion, smoother performance, and improved fuel efficiency.
Compare injector flow and detect leaks with clear graduated cylinders. Quickly identify faulty injectors—no need to replace the entire set.
Simulate Real Engine Conditions
Test injectors under different RPM ranges to simulate engine acceleration and operating conditions.
Manual Mode: 100–9900 RPM adjustable
Automatic Mode: Simulates idle to high-speed acceleration

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. Ideal for targeted testing at specific engine speeds during advanced troubleshooting.

Automatic Engine RPM Simulation Mode
Simulates engine speed automatically -from fast to slow, simulate real driving conditions. Adjustable test duration from 30 to 600 seconds supports quick checks or extended testing for more accurate, reliable diagnostics.
Batter Observation
Safer Injector Testing
Works with 6V/12V MPI Vehicles & Motorcycles
Monitor pressure in real time, track fluid levels with accuracy, and compare injector performance at a glance. Everything is designed to give you clear, reliable results - without guesswork.
Test fuel injectors safely without open spraying or flammable exposure. The JT200 provides a controlled, enclosed testing environment. No open spray, No fire risk, Stable and controlled operation.
Compatible with 6V/12V MPI top-feed injectors for vehicles and motorcycles. Includes a full set of Φ9–14.5mm adapters. Powered directly by the vehicle's 12V battery for convenient operation.
