FAQ
1. How to determine if ECU replacement is needed?
Intermittent stalling
Persistent DTCs (especially P0600 series)
Multiple sensor failures
15%+ abnormal fuel consumption
Failed programming attempts (3+ times)
2.Does post-installation calibration require special tools?
Solutions by tier:
Tier1 (Hitachi/CAT): Requires factory diagnostic tool
Tier2 (Chinese brands): Auto-adaptation available
Tier3 (Legacy models): Manual learning possible
3. What if ECU flashing fails?
Troubleshooting:
Verify CAN termination (60Ω required)
Ensure power supply >13.5V
Use shielded twisted pair (Belden 9841 recommended)
Request remote technical support
4.Bulk purchase benefits?
20+ units: 15% off + free programming
50+ units: 20% off + on-site training
5.: MCU vs ECU difference?
ECU: Controls fuel engines (injection, ignition).
MCU: Only for electric motors (no fuel involved).
