Who We Are

Madman Developments is a small company based in Johannesburg, South Africa. Our core business is the development and distribution of electronic engine and machine monitoring systems.

The first EMS2 started it all as just another installation product for 4×4 vehicles but the industry has grown to become a self-standing business with products found in many countries around the world.
