KMS MD35 Engine Control Unit

The KMS MD35 ECU is a fully programmable engine management system designed for motorsport, performance vehicles and advanced engine development applications.

Suitable as a standalone ECU for most gasoline engines up to 12 cylinders, the MD35 delivers complete engine control while maintaining a user-friendly tuning environment.

One of its key strengths is its integrated 38-channel data logging system, allowing detailed performance analysis and professional-level engine development. This feature enables tuners and engineers to optimize engine behavior based on real-world operating data.

The MD35 can take over ignition and fuel control at any desired engine speed, boost pressure or throttle position, providing exceptional integration flexibility.

When combined with KMS UEGO CAN controllers, the ECU provides self-learning lambda control for accurate air-fuel ratio management, helping maximize performance, drivability and engine efficiency.

With advanced functions such as launch control, anti-lag, traction control and boost control, the KMS MD35 is perfectly suited for motorsport and high-performance applications.
