Motorsport Electronics ME221 Gen2 With Unterminated 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 complete with a full unterminated harness.
