FECO X3 INSTALLATION GUIDE FOR CARS
Step 1: Start & Initial Check
-
Start the engine and let it idle for 3–5 minutes.
-
Check: engine vibration, engine noise, exhaust smell, black smoke (for diesel), muffler temperature.
👉 Purpose: create a “baseline” so customers can clearly notice the difference after installing FECO X3.
⚠ Note: FECO X3 only optimizes fuel intake combustion; it does not fix engine or mechanical faults.
Step 2: Preparation for Installation
-
Tools: heat-resistant cable ties, cleaning cloth, flashlight, pliers.
-
Product: FECO X3 set (depending on engine displacement).
-
Task: Activate electronic warranty before installation.
👉 Number of FECO X3 bars according to engine displacement:
-
≤ 2.0L → 3 bars (2 on the fuel line + 1 on the air intake).
-
2.0 – 3.0L → 5 bars (4 on the fuel line + 1 on the air intake).
-
3.0L → 6 bars (4 on the fuel line + 2 on the air intake).
Step 3: Installation & Fixing
Fuel line:
-
Mount FECO X3 on the fuel supply hose, as close as possible to the injectors and engine.
-
Secure tightly with cable ties to prevent looseness or slipping.
-
For enclosed engines (injectors under the intake manifold), ask customer permission if disassembly is required.
Air intake hose:
-
Mount FECO X3 after the valve/airflow sensor, as close to the engine as possible.
-
Secure tightly with cable ties.
👉 Technician tip: Cross the cable ties in an “X” pattern to prevent slipping; tighten firmly but avoid deforming the hose.
Step 4: Product Activation
-
Start the engine, press the accelerator and hold at:
-
2000 rpm → hold for 45s.
-
3000 rpm → hold for 45s.
-
3500 rpm → hold for 45s.
-
-
Then press and release the accelerator repeatedly for 60s (from idle to 3000 rpm).
-
Recommend the customer to take a short test drive to feel the effect.
👉 Purpose: flush out old fuel and allow fresh fuel to pass through FECO X3, activating its effect immediately.
Step 5: Inspection & Handover
-
Together with the customer, re-check: engine vibration, engine noise, exhaust smell, black smoke, muffler temperature.
-
Compare results before vs. after installation.
-
Complete installation form and warranty confirmation.
-
Advise customer:
-
FECO X3 lifespan is 5–7 years, with 3-year official warranty.
-
Effects are noticeable immediately and will become more stable after several dozen kilometers.
-
✅ Customer’s expected results:
-
Engine runs smoother, with less vibration.
-
Exhaust smell significantly reduced, cooler muffler.
-
Better acceleration, more responsive throttle, and noticeable fuel savings.
