Description

The MegaSquirt MS3Pro PnP ECU is a standalone engine management system designed for the 1990-1993 Mazda MX-5 Miata with a manual transmission. It offers a fully plug-and-play installation with no wiring required for basic functionality and comes with a pre-loaded base map to aid in starting.

This ECU supports real-time tuning and features 8 GB of internal data logging. It is compatible with most aftermarket wideband sensors and allows for the removal of the stock airflow meter. The system boasts 16x16 fuel and ignition tables for high-resolution tuning, along with 12x12 air-fuel ratio target tables for precise adjustments.
