MX5 ME442 Plug-In ECU Engine Management System

A Motorsport Electronics ME442 MX5 Plug-In ECU engine management system for the Mazda MX5 NBFL (2001–2005).

This easy-to-install Plug-In ECU with an integrated lambda sensor replaces the original circuit board inside the Mazda MX5’s factory ECU housing. Because the ECU fits into the original OEM housing and uses the original connector, this is a discreet and efficient way to upgrade the engine management system.

The system supports both the 1.6L and 1.8L engines with the same hardware.
