Haltech NEXUS S3 (ECU Only)

Haltech is well-known for its advanced engine management systems, and the NEXUS S3 is a prime example of their commitment to performance tuning. This unit is designed to give you granular control over your engine's operation, allowing for precise tuning to maximize power and efficiency. It's a sophisticated piece of hardware built for those who need comprehensive control over their engine's parameters.

The NEXUS S3 is built around a powerful 64-bit ARM Cortex processor, which means it can handle complex calculations and respond instantly to changing engine conditions. It features 10 universal auxiliary inputs and 8 universal auxiliary outputs, giving you a lot of flexibility to connect sensors and control various engine functions. With 512KB of RAM and 256MB of onboard storage, it has ample memory for extensive data logging and complex tuning maps. The unit also includes dual CAN bus ports for communication with other devices and a built-in Wi-Fi connection for wireless tuning and diagnostics, which can make the tuning process much more convenient.

This is the ECU only, meaning you'll need to source the necessary wiring harnesses and other components separately to complete your installation. It's important to note that this unit is not CARB approved and cannot be shipped to California. For a truly custom engine build where precise control and extensive tuning capabilities are paramount, the Haltech NEXUS S3 offers a robust platform.
