The Suzuki DF90A Engine Control Unit ECU 33930-87L20 is a genuine Suzuki OEM electronic control module designed for select DF90A four-stroke outboards. The ECU manages critical electronic engine functions using input from the engine's sensors to control fuel injection, ignition, and overall engine operation.

Suzuki parts diagrams identify 33930-87L20 specifically as the Engine Control Unit for DF90A applications. A model-specific 2013 DF90A diagram shows this exact ECU in the PTT Switch/Engine Control Unit assembly.

Compatible with the following:

• Suzuki DF90A (Select Models)
• Confirmed on 2013 DF90A applications

Because Suzuki used multiple ECU part numbers within the DF90A family depending on production year and engine configuration, the existing ECU part number and engine serial number should be verified before ordering. Suzuki listings, for example, identify 33930-87L20 as the DF90A/K13 ECU while later DF90A versions use other control units.
