4 Channel Wideband Controller 1357

The 4 Channel Wideband Controller 1357 is a precision data acquisition module engineered for serious engine tuning and performance diagnostics. Built by RacePak, a leader in motorsport instrumentation, this controller is designed for professional tuners, engine builders, and track enthusiasts who demand real-time air-fuel ratio monitoring across multiple cylinders. This four-channel wideband system provides critical feedback needed to optimize combustion and prevent costly detonation or lean-condition damage.

This wideband controller operates by processing voltage signals from four independent oxygen sensors, converting them into lambda or AFR (air-fuel ratio) values. The 1357 integrates seamlessly with RacePak's data logging ecosystem and third-party engine management systems, allowing you to log AFR events alongside boost pressure, ignition timing, and knock sensor activity. Its industrial-grade construction withstands thermal cycling and vibration common to high-performance vehicles.

The unit's compact footprint (5.5 x 3.45 x 10.8 inches) and lightweight design (2.54 lbs) make installation straightforward in engine bays with space constraints. This product is ideal for those looking to enhance their engine's performance, particularly in applications involving EFI tuning and data logging. With its compatibility with standalone ECUs and RacePak loggers, it is a valuable tool for serious automotive enthusiasts.
