We wanted to give some insight into the various options and prices for oxygen sensor controller setups that are supported by the OneGauge system. These controllers translate the signal for use by the OneGauge Hub so the readings can be displayed on your phone, tablet, or LCD screen.
They are ordered from highest to lowest cost; click on the name for a link to their website. All prices are as of February 2020, but shop around, you can often find them discounted on sites like Amazon.com.
Ballenger AFR500v2 : $315 – a tried and true, popular option for a standard controller. This price includes a Bosch LSU 4.9 or 4.2 sensor as well as optional NGK upgrades. It also supports 11-28 volt systems and many other fuel types including methanol.
Daytona WEGO III or IV: $262- built for racing, these are rugged sensors that also log data in the unit. Included is a Bosch LSU 4.2 sensor. They work on 11-16v systems and boast an accuracy of +/-.007 Lambda (about .1 AFR). Calibration is advertised as simple, open-air calibration.
Innovate LC-2: $180 – a more budget-friendly option, but some users complain of the need to frequently configure the controller. We recommend using a Bosch LSU 4.2 sensor as some users have complained that it doesn’t work well with the included 4.9 sensor.
Spartan Lambda Controller: at $125 with the LSU 4.9 (or $75 without), this inexpensive but well-reviewed controller provides .01 Lambda accuracy without the need for any calibration. A generous two year warranty on the controller is also included.
Wide-Band.com WB D1: $35 – a great unit for the DIY’er. The unit requires soldering to be assembled but it can be configured to support various types of fuel. It works with both Bosch LSU 4.9 and 4.2 oxygen sensors.
