Unlock the full potential of your engine with the ME221 Gen 2 Wire in ECU. This advanced engine management system delivers unparalleled control and precision tuning capabilities. Seamlessly integrated with your vehicle, it maximizes power, efficiency, and performance. Experience ultimate driving satisfaction with its user-friendly interface and cutting-edge features. Comes with the main connector and terminals to build your own wiring harness.

The ME221 Gen2 Wire-In ECU is a feature rich and future proof four cylinder injection engine management system. Built from the ground up using the latest control strategies means a modern, powerful, VE based ECU, with enhanced feature set including closed loop boost, in-built Wideband Lambda Control, CAN, on-board data Logging and VVT control – all in a compact form factor. Massive IO means the ME221 Gen 2 can handle anything thrown at it, and custom tables means any specific algorithms required can be easily derived.

The ECU comes with the main connector and terminals to build your own wiring harness.
