Description

COOBER LM ECU for Suzuki DR-Z4SM / DR-Z4S

The COOBER LM ECU for the new Suzuki DR-Z4SM and DR-Z4S is developed to improve throttle response, rideability and engine behavior on the Euro 5+ platform.

Modern Euro 5+ motorcycles are extremely lean in many riding situations. This can lead to jerky throttle response, hesitation at low RPM, unstable part-throttle behavior and excessive heat. The COOBER LM ECU works in parallel with the original ECU and optimizes the relevant control signals to improve the overall riding experience.

The system is fully plug & play and self-adjusting. It does not replace the original ECU and does not require manual mapping.

Main advantages

• Improved throttle response
• Smoother low-RPM behavior
• Better control at part throttle
• Reduced hesitation and surging
• Improved rideability in city, road and off-road use
• Self-adjusting system
• Plug & play installation
• Works with original exhaust and compatible exhaust modifications
• Developed specifically for Suzuki DR-Z4SM / DR-Z4S Euro 5+

Compatibility

Compatible with:

• Suzuki DR-Z4SM
• Suzuki DR-Z4S
• Euro 5+ models with dual Oxygen sensors

The original sensors must remain installed and connected for correct operation.

Installation

The installation is plug & play and can be completed without special tools. The ECU is connected to the original wiring harness using the supplied connectors.

No additional mapping or software update is normally required after installation.

 

Position the COOBER ECU centrally on top of the original ECU.

Route the cables along the frame and secure them with cable ties.

Route the two cables underneath the cover.

Connect the POST-CAT cable to the sensor located after the catalytic converter and the PRE-CAT cable to the sensor located before the catalytic converter. Both cables are clearly labeled. Secure all cables properly with cable ties.

Route the ground cable back to the battery.

Connect the ground cable to the battery negative terminal (MINUS / NEGATIVE).
