AutoMeter Wideband Gauge Options:
Street Series Wideband
The Street Series is an entry-level wideband gauge with a digital display, utilizing the Bosch LSU4.2 sensor. It offers an AFR range of 10:1 to 17:1, making it ideal for gasoline-powered street cars. This gauge also features data-logger output wires for those who want to integrate it with a data logging system.
Analog Series Wideband
For those who prefer a traditional gauge appearance, AutoMeter’s Analog Widebands feature a needle-style display with incandescent or LED illumination. Like the Street Series, it also uses the Bosch LSU4.2 sensor and has a slightly wider AFR range of 8:1 to 18:1. This model includes data-logger output wiring as well.
Pro Series Wideband
Stepping up to the Pro Series brings additional features for racers, tuners, and alternative fuel users. While it still uses the Bosch LSU4.2 sensor, it provides a user-adjustable AFR range from 6:1 to 20:1, making it adaptable for different fuel types. It also includes:
- Twice as many radial LEDs for finer resolution
- User-adjustable stoichiometric (stoich) values
- Peak recall and over-lean alarm
- Data logger output
- Auto-dimming display for night driving
- Switchable display between standard AFR and Lambda readings
Pro-Plus Series Wideband
The Pro-Plus Series includes all the features of the Pro Series and upgrades to the Bosch LSU4.9 sensor for enhanced performance and longevity. It also introduces Pro-Control output, allowing users to connect to a relay and trigger external devices based on AFR readings. Additionally, the Response Setting Mode lets users adjust the gauge’s refresh rate, catering to different racing or tuning scenarios. The Pro-Plus also includes serial output wires for direct PC or laptop connectivity.
