Work Description: FSOS:EFI: TIME: 1:00h
This service is focused on fuel-saving optimization and precision calibration for EFI-equipped scooters experiencing excessive fuel consumption, mileage drop, unstable RPM, throttle hesitation, engine overheating, or inefficient combustion behavior.

Each scooter undergoes ECU data scan, fuel trim optimization, O2 sensor performance check, injector flow analysis & cleaning, throttle body airflow inspection & calibration, IACV/ISC adjustment, MAP/TPS sensor health test, CVT system inspection (roller/belt condition), fuel pressure & pump performance evaluation, and intake–exhaust efficiency analysis.

We utilize OEM-grade diagnostic equipment, manufacturer-standard testing protocols, and real-time live data interpretation to identify actual fuel loss causes—not assumptions. Optimization actions may include injector cleaning, throttle body service, idle recalibration, sensor synchronization, CVT tuning, fuel-air ratio correction, and electrical signal verification.

Outcome: improved mileage efficiency, reduced fuel wastage, stable RPM, smoother throttle response, optimized combustion, and overall enhanced riding performance under real-world conditions.

Includes: Post-service diagnostic report & 30-day service assurance on performed optimization.

Engineered for modern EFI scooters. Tuned for maximum fuel efficiency and operational reliability.
