Syvecs 2.5m PnP cable + LSU 4.9

Syvecs Bosch LSU 4.9 Wideband Sensor and 2.5m PnP Cable

The Syvecs SYV-LSUPNP kit is a complete wideband oxygen sensing solution designed for professional engine management. This kit bundles a genuine Bosch LSU 4.9 wideband sensor with a high-quality 2.5-meter Plug and Play (PnP) extension cable. It is specifically engineered for users of the Syvecs S7, S8, S12, and X-series expanders, which feature built-in wideband controllers.

The LSU 4.9 is the industry standard for precision fueling, offering faster response times and greater accuracy than older wideband technologies. By using this kit, the ECU can perform closed-loop fuel corrections, ensuring the engine stays at the target air-fuel ratio (AFR) during everything from idle to high-boost wide-open throttle runs.

Performance and Precision Engineering

The included 2.5m cable is constructed using motorsport-grade wiring to ensure the sensitive low-voltage signals from the sensor are not compromised by electromagnetic interference.

• Laboratory Grade Accuracy: Capable of measuring Lambda from 0.65 to lean air-fuel ratios with microsecond resolution.

• Plug and Play Integration: The cable features the correct 6-pin Bosch connector for the sensor and pre-terminated pins or connectors for the Syvecs ECU side, eliminating the need for complex loom work.

• Advanced Heater Control: Optimized for use with Syvecs' sophisticated heater control logic, which prevents thermal shock and extends sensor life.

• Shielded Wiring: The extension lead is designed to protect the "Pump Current" and "Nernst Voltage" signals from engine bay noise, providing a stable reading on your datalogs.

Wiring and Connection Data

The LSU 4.9 sensor utilizes a factory-calibrated trim resistor within the connector body. This means no "free-air" calibration is required when moving the sensor between vehicles, provided it is used with a Syvecs controller.
