The AutoMeter Pro Wideband AFR kit provides accurate, automatic calibration on every startup and supports nearly all fuel types for precise air/fuel monitoring. The kit includes a custom-tuned Bosch LSU4.2 sensor, an 8 ft wiring harness, a stainless weld-in bung and mounting hardware. Configurable display ranges, automatic dimming, peak recall and a lean-warning system help protect engines during tuning, while 0–4V data output enables ECU or logging integration.
