AEM Digital Wideband UEGO Gauge without Sensor 304110NS User Manual
All AEM digital gauges feature a v analog output for use with data loggers and almost any engine management system. The Bosch 4. The 4. The sensors are not interchangeable between the two gauge controllers in any way, including changing connectors on the gauges. Instructions for the will still be available in the Instructions tab after this change. Accurate AFR data is critical when tuning an engine. What is free-air calibration? Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels. We use Bosch 4. Our sensors are individually laboratory-calibrated by Bosch and never require free air calibration! This resistor is specifically created for the exact sensor that it is attached to. Close menu.

This can be done by clicking on the Sensors Tab at the Unplug the O2 Sensor from the Gauge. View all the pages. Add page 1 to Favourites. Enable zoom. This installation is not for the electrically or mechanically challenged! If you are uncomfortable with anything about this, please refer the installation to an AEM trained tuning shop or call for technical assistance. This product is legal in California for racing vehicles only and should never be used on public highways. Add page 2 to Favourites. The AEM gauge is ideal for all vehicles including carbureted applications and engine dynamometers. A serial data stream is also integrated for air fuel or lambda ratio output to a RS com port. With this, there is no abrupt oscillation as found in many competitor gauges, which utilize a narrow band oxygen sensor detecting only stoichiometry. Add page 3 to Favourites. This is a very cost effective method that outputs a voltage based on the oxygen content of the gas being sampled.
“Why do I need to calibrate the O2 sensor with Innovate products?” The answer is simple… Accuracy!
Innovate Motorsports is the first wideband O2 device manufacturer on the market that allows the user to field calibrate the O2 sensor. The Bosch factory sensor calibration is done using a fixed atmospheric pressure value that may be incorrect for your location from the start! This sensor has an integrated calibration resistor located in the connector on the plug end. Like all sensors in a vehicle, O2 sensors wear over time and being able to recalibrate the sensor is the only way to ensure continued accuracy. Innovate Motorsports makes it possible for the sensor to be recalibrated because we do not rely on or utilize the Bosch calibration resistor. Without the ability to calibrate, your wideband will continue to rely on the Bosch factory pre-calibrated resistor settings as your sensor wears. The results of doing so have been published by Bosch in a technical document referenced below:. In aftermarket performance applications where engines typically see richer conditions with higher exhaust gas temperatures, the sensor will degrade at a greatly accelerated rate compared to the Bosch spec. Other factors such as detergents, additives in the fuel, sensor placement and lead will also accelerate sensor wear even further. The Innovate Motorsports patented digital wideband sensor controller technology eliminates any and all inaccuracies caused by sensor wear. Calibrate before installation of the new sensor. Calibrate the sensor again after 3 months of use. Thereafter calibrate once a year or every 20, miles, whichever comes first. Changes in altitude will also affect the accuracy of the measurements. It is important to note the Bosch spec tests the accuracy of the sensor at In the same way that the pre-calibrated resistor can not compensate for sensor wear, it can not compensate for changes in altitude. The difference in altitude is approximately ft. If you do not have the ability to calibrate your sensor, and you happen to live in Denver ft. If you are using a wideband system that does not allow the sensor to be recalibrated, you are putting your engine at risk. The results of doing so have been published by Bosch in a technical document referenced below: LSU test bench at constant 20 degC gas temp and constant
Wideband O2 Sensor
The AEM gauge is ideal for all vehicles including carbureted applications and engine dynamometers. A serial data stream is also integrated for air fuel or lambda ratio output to a RS com port. With this, there is no abrupt oscillation as found in many competitor gauges, which utilize a narrow band oxygen sensor detecting only stoichiometry. This is a very cost effective method that outputs a voltage based on the oxygen content of the gas being sampled. It is accurate in the region surrounding stoichiometric operation and leaner. Unfortunately, in the rich region where high performance engines usually operate, their accuracy and repeatability is virtually non-existent. Figure 1. The rich region output of narrow band O2 sensors is temperature dependent, which renders it useless if an accuracy better than 1. This is immediately obvious given the fact that a single output voltage actually represents wildly different air fuel ratios depending on the unregulated and unmeasured sensor temperature. These sensors were designed for operating closed loop around stoichiometry Its unique design makes precision AFR measurements possible over the entire operating range. The output is in the form of a very small current, which varies depending on the air-fuel ratio. This is completely different from a narrow band oxygen sensor, which directly outputs a voltage. The UEGO sensor design allows measurement of the exact air fuel ratio over the entire operating range. Figure 2. Disconnect the negative - battery cable. The longer harness connects to the UEGO sensor. The shorter harness contains four leads. The red and black leads must be connected in order for the gauge to function. Connection of the white and blue wires is optional. Connect the wires as shown below. Figure 3 The harness ends with the four and six pin connectors connect to the back of the gauge. When looking at the back of the gauge as shown below, the six-pin connector connects on the left side and the four pin on the right side. The locating tabs on the four and six pin connectors should be facing up. Figure 4. Table 1. When in this state, the UEGO gauge will output 2. Unplug the O2 Sensor from the Gauge. Click Apply and close screen. Next navigate to the O2 Sensor 1 Cal Table. This can be done by clicking on the Sensors Tab at the top of the screen or using the Display Explorer. Double click to open the following tables. Channels — O2 Sensor Table a. If the channel in AEMtuner is not displaying the correct Consult the documentation provided with the system for detailed instructions. The serial output can be used for data logging when an EFI system is not accessible. Two wires need to be connected to a RS serial port. Pin 5 GND on the serial port shall be grounded. However, this should be confirmed with a continuity tester before attempting.

Wiring Information: 1. Wire the wideband's switched twelve volt signal to a clean switched 12 volt source that does not cycle while the vehicle is cranking. Wire the wideband's ground wire to a clean ground source battery. You will need to wire your wideband's analog volt output to the input you selected to use on the ecu. When using an innovate mtx-l the signal wire is yellow. When using an aem uego the signal wire is white. When using a PLX wideband the signal wire is what ever color output you selected Usually gray. The two light blue resistors are r and r Do not remove the brown resistor between them. Software Setup: 1. Open the Smanager software. Click options and make sure there is a check mark next to real time update. If there is not click real time update. Click on Paremeters then click the Closed Loop Advanced tab. Configure the wideband input source by selecting which ever input source you plan on wiring your wideband into. Once your input source is selected you will need to configure your voltage conversion table using the charts pictured:. Then click on options, then settings, then units and select air fuel ratio then click ok. If the air fuel ratios are slightly off between your gauge and your s system you may have to adjust the voltage offset. You can use a negative or positive value for an offset. For example Also make sure Disable o2 heater is checked if you are not running a factory o2 sensor. My Account. Orders Comparison list Wish list Track my order s. Track my order s. Sign in Register.
