With its distinctive gold ECUs and a philosophy of engineering excellence, MoTeC has grown from a modest home workshop producing a screwdriver-adjusted ECU in the late 1980s to a world leader in twenty-first century motorsport technology. Now boasting a network of over two hundred authorised dealers worldwide, and with main offices in Europe and the USA, this innovative Australian brand has become synonymous with motor racing success in almost every category across the globe.

The C125 is striking in design and powerful in functionality, with display, data logging, auxiliary control and programmable LEDs all in one compact device. This model now also provides a composite video input as standard (e.g. for a rear vision camera), and USB Logging to a removable storage device as an optional upgrade.*

The vivid 125mm screen (approx 5") is high resolution, ultra bright and anti-reflective for easy reading in direct sunlight. Choose from numerous selectable layouts and configure the channels and labels to suit, or opt for the Display Creator upgrade and treat your screen as a blank canvas with unique graphics, images, logos and custom icons. Create multiple pages to suit different scenarios, optimising the screen space for your application.

The C125 also features ten full colour LEDs integrated into the unit for use as shift lights, warning lights or other driver alerts. The colour, function and intensity of each LED is programmable, allowing users to develop their own unique strategies and sequences.

The C125 is available standalone or as part of MoTeC's C125 Race Kits.

*Note: USB Logging and Live Video are recently added features that may not be available on devices already purchased. Compatible hardware can be identified by a mini USB port on the back of the unit.

Also available: C185 Display Logger
