⚙️ ECU Tuning Services (Send-In)

We offer professional ECU calibration services for many modern outboard motors. All tuning is performed in-house on customer-owned ECUs that are sent to our Swedish facility.

  • Yamaha outboard ECUs
  • Suzuki outboard ECUs

⚠️ Disclaimer: Our ECU services are intended for off-road, competition, or closed-course use only. It is the customer’s responsibility to ensure that tuning complies with local laws, warranty terms, and insurance policies.
