4 Channel Wideband Controller 1357

The 4 Channel Wideband Controller 1357 is a precision data acquisition module designed for engine monitoring and performance analysis in high-demand automotive and powersports applications. Built for professionals who demand real-time multichannel sensing, this controller integrates seamlessly with Racepak V-Series recording systems to capture critical engine parameters across four independent channels. Whether you're tuning a competition engine, diagnosing performance issues, or validating calibration changes, this controller delivers the multichannel input architecture required for serious dyno work and trackside data logging.

This 4-channel wideband controller features a dedicated left cylinder bank configuration with dual cable harnesses: a 13-inch pigtail for sensor connection and a 37-inch main controller cable for integration with Racepak V-Series recorders. The compact 5.5 x 3.45 x 10.8-inch form factor and lightweight 2.54-pound design allow flexible mounting in tight engine bays or data acquisition housings. Wideband sensing technology provides millisecond-level response to AFR (air-fuel ratio) transients, enabling precise fuel mixture monitoring across idle, cruise, and wide-open throttle conditions—critical for turbo tuning, carbureted engine diagnostics, and emissions compliance validation.

This controller is essential for engine builders, performance shops, and motorsports teams running Racepak V-Series data acquisition platforms. Installation requires integration with wideband oxygen sensors mounted in the exhaust manifold or collector and connection to compatible Racepak recorder units via the 37-inch controller harness. The left cylinder bank focus makes it ideal for V-engines, flat-fours, and inline configurations where independent cylinder-bank monitoring improves tuning resolution. Proper sensor calibration and harness routing ensure signal integrity and accurate AFR logging during all engine operating conditions.
