AiM Cobra ECU Plug & Play Engine Control Unit

Cobra is the brand-new aftermarket plug & play ECU created by AiM, exclusively designed for off-road bikes. Thanks to its high technology 32-bit core, it represents an important step forward to improve the performance of your bike, without sacrificing reliability and smoothness.

This specific Cobra ECU is unprogrammed. It can be configured for any brand or model bike you require. You will need the UC Bridge Tuner to enable this process.

Once the unprogrammed Cobra ECU has been configured with a dedicated brand or model it can not be changed. You will be able to modify the maps written into the ECU but the brand or model which has been configured can not be changed.

It provides the ultimate control in feeling, ignition, ignition phase, start maps, launch control, traction control with altitude and engine temperature corrections.

Traction Control Strategy

For each map, the ECU has a dedicated traction control main table.

Launch Control

For each map, the ECU has a dedicated launch control main table.

High Technology 32-bit Core

Engine control requires precision. At 20,000 RPM the Cobra ECU guarantees the precision of 1/10 of the degree: this means an accuracy within 0.8 uses for turning the spark ON!

This precision is the key to guarantee :

A very consistent engine rotation.

The possibility to repeat dozens of tests at the bench, always obtaining the same result.

A perfect reactivity at every minimum change of any point of a map, resulting in more power at the wheel.

UC Bridge Tuner - Optional Extra 

The UC Bridge is the connection between the CAN bus of the ECU and the USB port of your PC. 

Tuner License :

This is the Tuner that is required to configure the unprogrammed Cobra ECU.

With this license, the tuner can create different maps, configurations and strategies designed for the rider's bike. The tuner can then flash them directly onto the ECU or send them via email to allow the rider to download and install them in the ECU.

*Please Note: For information regarding the UC-Bridge Tuner, please contact one of our AiM technical team for further information.

Main Connector - Compatible with most off-road bikes.
CAN Connector - Connects to the Handlebar Switch and Data Logger.
