The compact and lightweight MLS is dedicated to Chevrolet LS1 and Lexus/Toyota V8s, providing a price competitive solution for this range of popular engines.

A derivative of the M4 engine management system, it has all the benefits of performance and reliability associated with this earlier generation ECU.

The DOS-based tuning software is efficient and easy to use with the same functionality as the M4 ECU Manager software.
