Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing ECU controller can initially manifest as intermittent engine sputtering or a check engine light illumination. If ignored, the engine may experience unpredictable power delivery, stalling, or fail to start altogether. Continued operation with a faulty ECU risks damage to other engine components due to improper control.

Installation Tip

Ensure the battery is disconnected and properly grounded before removing or installing the ECU controller to prevent electrical surges. Avoid exposing the ECU to excessive moisture or extreme temperatures during installation.

Service Note

After installing a new ECU controller, it is crucial to perform a diagnostic scan and recalibrate the engine control module to the specific equipment.
