Universal Wideband O2 Kits
This is a thread in regards to the available wideband O2 sensor kits available on the market. These come in handy when tuning your ride, optimizing the air/fuel ratio for better performance, and even fuel economy.
Basic Information:
14.7 is considered stoichimetric (perfect)
The higher the number, the Leaner the Air/Fuel is.
The lower the number, the Richer the Air/Fuel is.
AEM Gauge-Type Wideband UEGO Controller
Webpage
A wideband UEGO sensor controller accurately monitors Air/Fuel ratios (AFR) during the tuning process to prevent a lean fuel mixture, which could lead to engine damage. AEM has combined its single-channel wideband UEGO controller and gauge display into one unit, uniting unsurpassed AFR accuracy and control with an easy-to-read interface. AEM’s Gauge-Type Wideband UEGO Controller features a digital LED display and sweeping LED “needle” that changes colors as AFR changes from rich to lean. The unit’s 52mm (2-1/16”) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere.
Features:
Ideal AFR monitoring tool for EFI and carbureted applications, and engine dynamometers
Does not oscillate AFR reading like narrow band sensors
No laptop required for monitoring!
Bosch sensor included
Accurate to 0.1 AFR
Reads in AFR or Lambda via a switch in back of gauge housing
24 Color-coded LED display lights provide immediate reference to engine’s air/fuel ratio (AFR) or Lambda ratio
Integrated three-digit display reveals AFR or Lambda in real time
User-programmable 0-5v analog output included for use with data loggers and virtually any engine management system
Serial data stream included for output of AFR (RS 232)
NGK Powerdex AFX
Webpage
NGK Spark Plugs (USA), Inc. is introducing its new Powerdex AFX Wideband Air-Fuel Ratio Monitor for the performance aftermarket. This product meets the increasing demand in the market for precision air-fuel ratio monitoring tools.
Traditionally these types of tools commanded price tags that could only be justified by professional race teams and engine specialists. As technology advanced, many low-cost air-fuel ratio products emerged. Some used actual wideband sensors while others simply read OE style narrowband oxygen sensor signals and attempted to convert them to linear readouts….often with marginal success.
The AFX Air-Fuel Ratio Monitor offers the most affordable wideband system to date. A flexible and rugged system complete with everything needed to get you tuning. The kit comes with a digital display control module, 13’ wiring harness, wideband air-fuel ratio sensor, exhaust boss and plug, and a comprehensive tuning manual. The tuning manual includes installation instructions and contains a detailed guide to performance air-fuel ratio tuning.
The AFX measures and displays air-fuel ratio (AFR) from 9.00 to 16.00. It demonstrates superb response and accuracy within 0.1 AFR. The air-fuel ratio information can then be utilized by the user to make fuel delivery adjustments to the vehicle’s carburetor, mechanical fuel injection, or programmable electronic fuel injection system. The desired air-fuel ratio can be achieved depending on the performance requirements of the engine or race application. This is an exceptionally useful tool for carbureted engines, where there is a lot of freedom in tuning as well as a great need for proper adjustment.
Innovative Motorsports LC-1 Wideband Controller
Webpage
The LC-1 Lambda cable is a complete wideband controller built in to a sealed cable. It features the same award-winning patented digital measurement principal found in the LM-1, and includes digital input, output, and 2 user programmable analog outputs.
The LC-1 is more accurate than conventional designs costing many times as much, and its self-calibrating circuitry can compensate for changes in temperature, altitude and sensor condition. The LC-1 is ideal for applications such as Dynos, Data Acquisition, Standalone ECUs, piggyback fuel controllers, OBD-II software or chip programmers, and gauges. With the LC-1, you can add additional wideband channels to your LM-1, convert an existing narrow-band gauge, or add wideband capabilities to your dyno. You can even tune individual cylinders by using multiple LC-1 kits.
Features:
Only fully digital wideband controller.
Auto calibration capability to compensate for changes in temperature,
altitude, and sensor condition.
Two user programmable analog outputs.
Permanent install applications
Cost effective individual cylinder tuning.
Easy to upgrade.
Includes LogWorks software
