  • The Air Control MAP option for vehicle ECUs allows for precise adjustment of the air-to-fuel mixture, enhancing engine performance and efficiency. By tuning this parameter, users can optimize throttle response, reduce emissions, and maximize power output. This option is an essential tool for achieving optimal engine performance and achieving better fuel economy.

  • Engine torque limiters are an essential MAP (Manifold Absolute Pressure) option for ECU tuning in vehicles. These limiters help ensure the engine operates within its optimal torque range, preventing excessive strain and potential damage. By carefully adjusting and optimizing torque limits, vehicle performance and efficiency can be improved while maintaining the engine's longevity.

  • The MAP option for the ECU allows for precise adjustment of engine torque request in vehicle tuning. With this feature, optimal power delivery and performance can be achieved by customizing the torque output to suit specific driving needs, maximizing the driving experience while maintaining reliability.

  • The Exhaust Gas Temperature (EGT) MAP option allows for precise monitoring and control of the vehicle's exhaust gas temperature. By adjusting the fuel and air mixture, it optimizes performance, enhances fuel efficiency, and reduces emissions. This option is essential for ECU tuning, as it ensures the engine operates within safe temperature limits, prolonging the life of critical engine components.

  • The gearbox torque limiter MAP option for the ECU allows precise control over the maximum torque output of the vehicle's gearbox. By adjusting this setting, you can optimize the power delivery and improve the shift quality, ensuring optimal performance and durability. This allows for a customized driving experience and better overall gearbox performance.

  • The Idle Speed RPM MAP option is a feature in vehicle ECU tuning that allows for precise control over the engine's idle speed. By adjusting the RPM parameter, you can optimize the engine's performance during idle periods, leading to smoother idling and improved overall engine efficiency. This option ensures an optimal idle speed that suits your vehicle's requirements.

  • The MAP option for the vehicle's ECU is designed to optimize fuel injection system performance. By accurately measuring and analyzing the manifold absolute pressure (MAP), this option allows for precise fuel delivery and improved engine efficiency. This tuning feature ensures optimal power output and fuel economy, enhancing the overall driving experience.

  • The MAP option for the ECU allows for fine-tuning of the rail pressure in a vehicle. By adjusting the rail pressure, it's possible to optimize fuel delivery to enhance power and efficiency. This option allows for precise control over the fuel system, ensuring optimal performance and responsiveness. Unlock the full potential of your vehicle with the MAP option for ECU tuning.

  • The Smoke Limitation MAP option for vehicle ECU tuning helps to control smoke emissions from the engine. It optimizes fuel delivery and air intake to reduce smoke production, ensuring compliance with environmental regulations. By fine-tuning the injection timing and duration, this option minimizes the visible smoke that is released during acceleration or high load conditions, promoting cleaner and more efficient operation.

  • MAP Option: Start of Injection (SOI) The Start of Injection (SOI) MAP option for the Vehicle Engine Control Unit (ECU) allows precise control over the timing of fuel injection. By determining the exact moment when fuel enters the combustion chamber, this option optimizes engine performance, fuel efficiency, and emissions. Achieve enhanced power delivery and responsiveness with this essential tuning feature.

  • The turbo boost pressure MAP option allows for precise control and optimization of the boost pressure generated by the turbocharger in a vehicle's engine. By adjusting the boost pressure, this ECU tuning feature helps enhance power output and torque, improving acceleration and overall performance. Fine-tuning the turbo boost pressure can also help maximize fuel efficiency while maintaining engine reliability.

  • Turbo Boost Pressure Control is a MAP (manifold absolute pressure) option for vehicle ECUs. This feature allows for precise control and adjustment of the turbocharger's boost pressure output. By optimizing turbo boost levels, it enhances engine performance, torque delivery, and overall vehicle power. This advanced functionality ensures efficient power delivery and a dynamic driving experience.
