 What is Woolich Racing AutoTune? |
Woolich Racing AutoTune is a feature currently available in the Woolich Racing Tuned software. AutoTune works with data logged either from the Engine Data Screen or when using the Woolich Racing Log Box. The logged data is sorted and analyzed and changes are provided which will bring the Air Fuel Ratio (AFR) of your bike closer to the Target AFR. The AutoTune process involves the following steps. - Data Logging
- Review Logged Data in the Woolich Racing Tuned Software.
- Apply suggested changes to the Fuel Maps
- Write changes to the ECU
- Repeat from step 1 until you have reached your Target AFR and the suggested changes are small.
AutoTune allows you to tune both IAP and TPS maps. These Support Center articles may also be of interest to you:

| Woolich Racing Tuned - Data Viewer |
The Woolich Racing Tuned software allows you to read and write to your ECU but also includes a lot of other features for reviewing logged data in order to optimise the tuning. The Data Viewer is a tool which allows you to open logged files of Engine Data and view these and perform some other useful functions. This article described how to use the Data Viewer effectively to get the most out of this software tool.
To open the tool you can click on the 'Data Viewer' button in the main window of the Woolich Racing Tuned software as shown below:
Once you have opened the Data Viewer you will need to open a previously logged file containing Engine Data. These files are saved to the micro SD card of the Log Box and can be opened using the 'Open Log File' button as shown below:
Once you have opened the Log File you should see the data displayed on screen, the example in the image below is for data logged on a 2016 MT-10:
Configuring the Data Display
In the image above we can see two graphs; the first shows AFR, TPS% and ETV and the second shows RPM, Gear and Manifold Pressure. The data displayed can be freely configured by selecting File > Configuration as shown below:
The software will then display the 'Data Log Viewer Configuration' as shown below:
This window can be used to modify the number of graphs displayed and the the parameters displayed on each graph including the colours of the different data traces. It is also possible to adjust the Y-axis for any of the data traces on the graphs and this configuration will be saved when you click on the 'OK' button.
Navigating Through the Data
The graph data can be navigated in a number of ways using either the buttons on the bottom of the Data Viewer window or the mouse wheel. The various arrow buttons on the bottom of this window allow you to jump forward or backward through the data while the '+' and '-' buttons allow you to zoom in and out.
The mouse pointer can be moved around the graphs and the data values will be displayed on screen for the specific time period where the mouse is located. If rotate the mouse wheel down you can scroll forward through the data, rotating the mouse wheel up moves backwards through the data.
Zooming in and out can also be performed by holding down the 'Ctrl' button on your keyboard while rotating the mouse wheel up or down. This allows you to quickly select and view different regions of interest and zoom in on them to review the data.
Selecting a Range of Data
A useful feature is the ability to select a specific range of logged data and this can be exported to an xml file or exported directly into AutoTune as described below. To select the start of the data range you can simply click anywhere on the graph with the left mouse button. You will see the starting time value that you selected displayed on the bottom right under 'Export Timespan'. To define the end of the time range you can hold down a 'Shift' button on the keyboard and left-click on the graph again. You will then see a second time added to the 'Export Timespan' which should now define a specific time range as shown below. If you need to adjust the start or end times you can simply repeat the process above.
Note that if you click the left mouse button on the graph the start time will be set and the end time will be erased - if you export data in this state the entire data set will be exported as there is no valid range selected.
Exporting a Range of Data to AutoTune
A new and very useful feature of the Data Viewer is the ability to select a specific range of logged data before exporting this directly to AutoTune. The AutoTune feature has always allowed users to load a Log File (File > Open Log File) however this loads the entire Log File into AutoTune and sometimes we do not necessarily want to include the whole data set. This is especially useful for large data logs where not all of the data is always useful and you might like to eg. select dyno pulls for specific gears only. By selecting a valid range of data and then selecting File > Export to AutoTune (as shown below) the data will be automatically exported to the AutoTune window where the AFR data will be displayed as shown below:
The data exported into AutoTune can then be used as normal to modify the fuel maps to achieve Target AFR values, except in this way the AutoTune only uses the data that was selected and exported from the Data Viewer.
Exporting a Range of Data to an xml file
Another useful feature is the ability to select a specific range of logged data which can be exported to an xml file for eg. analysis with another software package. After selecting a valid data range using the method described above, you simply select File > Export to XML (or press Ctrl + E) and then provide a filename and location to save the file. Only the selected time range will be exported so it is possible to export several smaller ranges from a larger data log file. These exported XML files can also be imported again by selecting File > Open and then selecting the appropriate *.xml file.
Data Viewer - Live
The Data Viewer can also be opened directly from the Engine Data window while viewing live data which offers a useful alternative to viewing only the current values. The Engine Data is updated several times per second so always shows the current measured values, while the Data Viewer shows the complete history by graphing the Engine Data against time.
Data Viewer - Live can be started from the Engine Data window by clicking on the button as shown below:
This will open the Data Viewer which is populated with live Engine Data and graphed using time as the x-axis, these plots are updated in real time allowing you to monitor changes on the bike. These graphs can be fully customised to display various parameters as described above under 'Configuring the Data Display'

| AutoTune - Using AutoTune and AutoTune Live |
Woolich Racing offers two different methods for tuning your bike using AFR data (Air-Fuel Ratio), AutoTune Live uses realtime data while the bike is running on a dyno while AutoTune uses data that was collected previously while riding the bike on the street, track, etc.
AutoTune Live is ONLY available for dyno tuning. We have a comprehensive Auto Tune Live User Guide document which will guide you through the specific details of using AutoTune while running on a dyno.
AutoTune is available to use with previously logged AFR data and does not require the use of a dyno. If you are using this data logging method please refer to our Auto Tune User Guide instead.
Before you start using the Woolich Racing AutoTune it is recommended you ensure the following is taken into consideration:
- You will need a Log Box or Log Box Pro Interface (hereafter referred to as ‘Log Box’). The Log Box is a Woolich Racing product that connects to your electronic control unit (ECU) to log engine data from the ECU and AFR from a wideband oxygen sensor. If you do not have a Log Box and a wideband oxygen sensor, then you cannot use AutoTune.
- The Log Box connects to a Woolich Racing on bike harness, the on bike harness connects to the Diagnostic Plug on your motorcycle. The diagnostic plug provides the real time engine data directly from the ECU.
- You should have your motorcycle in optimum serviced condition, particularly with regard to air cleaner and spark plugs, oil and filter. Ensure you have no exhaust leaks as this also detrimentally affects logged AFR and therefore AutoTune results.
- Ensure the PAIR Valve is blocked off. You can do an internet search based on your motorcycle brand and model to determine how to block off the PAIR valve. It may also be referred to an Air Injection System (AIS).
- Rider Aides including Traction Control, Slip Control, Wheelie Control etc. should be turned off while logging data to be used for AutoTune. These features can affect the AFR when they are active which will result in the logged data containing incorrect AFR’s.
- To begin an AutoTune session you will need access to one or more log files generated by the Log Box. It is recommended to have at least 15-30 minutes ride time logged for each log file.
- You will need to measure or obtain the Header Pipe Diameter and Header Pipe Length so you can enter the parameters for the Exhaust Gas Offset.
- If you can select different ride modes on your motorcycle such as Full Power, Rain etc. ensure you select the correct mode that you are tuning for before test riding.

| Bin File Configuration (Map Unification) in WRT |
The Fuel and Ignition maps in the ECU allow you to edit down to the Individual Cylinder Maps. There can also be Group Maps which provide other groupings of Fuel and Ignition Maps e.g. Gear Groups or Upper and Lower Injectors. When editing maps and/or using the Woolich Racing AutoTune it is much easier to work with a unified set of maps. This allows you to edit one map and the changes are applied to all of the associated maps.
If you unify Fuel Cylinder maps, when you edit the Fuel Maps you will only need to change one Fuel Map and the changes will be applied to all of the cylinder maps. You can configure Fuel and Ignition map unification settings in the "Bin File Configuration" screen shown below. You can gain access to this screen by clicking on the "Configuration" button on the main screen in WRT.
'Bin File Configuration' window showing Fuel/Ignition Map Unification settings
Unifying and 'Maintain cylinder offset' presents you with one map to change, and the software handles the differences between the individual cylinders automatically. If the factory setup is for each cylinder to get a different amount of fuel, then the software will handle all those differences in the background, and you just need to change one map. Unifying and setting it to a particular cylinder, also presents you with one map to change, but will make all cylinders use that same cylinder's map. Any changes are applied across all cylinders evenly, with the same values (same map for all cylinders). This video shows you how to use the Bin File Configuration section of the Woolich Racing Tuned software to unify fuel and ignition maps for easier editing.

| AutoTune - Other AutoTune Considerations and Troubleshooting |
The Target AFR maps that are supplied by Woolich Racing are designed to be used as a good starting point and baseline for AFR tuning. This means that it is not necessarily the perfectly optimal AFR map for your bike, and there are several factors that can affect how well the Target AFR maps works. AFR target maps should be adjusted to meet your particular tuning objectives, and conditions. You will need to weigh up factors such as fuel economy, engine running temperature, preventing engine knock, and power/performance.
When logging AFR on the dyno, there is less air entering the airbox compared to when the bike is running on the road.
O2 Wideband sensors are not always 100% precise; they do wear out over time and two different wideband sensors can show differing AFR values.
Usually you will start with AutoTune strength at 100%, and Maximum % Change between 10.0 and 15.0. It is a good idea to begin reducing the AutoTune Strength % and Maximum % Change after each iteration of using AutoTune.

| AutoTune - Multi-Cylinder Tuning |
Many bikes have a single exhaust which means that the exhaust gases from different cylinders are mixed together and AFR values that are read from a single sensor are then a combination from different cylinders. On bikes which have multiple exhaust pipes it is possible to measure the AFR on all pipes and tune the cylinders individually. Note this method requires bungs to be installed on each header pipe.
To map the cylinders individually with a single ZT-3, you would follow these steps. First ensure that you have not unified fuel cylinder maps, as you need to select each one individually. - Connect everything up to prepare for Live AutoTuning.
- Fit the O2 sensor to Cylinder 1, and Open Engine Data, click Autotune Live, in Autotune select CYL1
- Complete the usual process - AutoTune Live for that cylinder
- Click 'Apply Autotuned Map', to save that cylinder's settings to your currently open Bin File. Note that only the data for the selected cylinder is saved to your bin file.
- Close the AutoTune window.
- In the Live Engine Data window, click Stop, then click the blue numbers to clear the current log files. (resets to 0) to clear out the logs for Cylinder #1.
- Then move the sensor to Cylinder #2, and repeat the steps above with each cylinder on the bike

| Engine Data logging settings |
The Woolich Racing Log Box products allow data to be written (logged) to an micro-SD card while the bike is being run on the street, track or dyno. The Log Box will typically start logging data whenever the ignition is started AND the device is NOT connected to the computer.
The exact settings about how the data logging works can be modified by the user in the Woolich Racing Tuned software on the computer. These settings can be viewed by connecting the Log Box to your PC and setting your Log Start Configuration which can be found under Tools > Device Configuration Page as shown below.
The Log Start Configuration is shown as in the screenshot below:
The Default "Log Start Configuration" settings are:
Time Delay (secs) = 0 - The number of seconds to delay before starting to log data after the device is powered on. This setting is useful if you would like to delay data logging to prevent log files from being created when starting the bike for short amounts of time.
Engine Running = not ticked - When this option is checked the engine must be running before data will be logged. This setting is useful to prevent logging data when the key is turned on but the engine is not running.
RPM = 0 - The RPM that the engine must go above before data logging will begin. This setting is useful to delay the start of data logging until the engine has been taken above the selected RPM.
Log data to micro-SD in Engine data Mode = not ticked. - This setting creates data logs on the Interface when in normal operation mode. It is useful if you are using the Interface on the dyno to monitor engine data and you would also like to log data to be used with the Woolich Racing AutoTune.
OBD2 Engine data = not ticked - This option is required for models that use OBD2 engine data protocol. You can see it your model requires OBD2 data by checking the Engine Data Type' in the Bin File Details. If your model shows the Engine Data type: "OBD2 - CAN", then you will need to tick this option, and save to the Log Box.
CAN Logging = not ticked - This is a troubleshooting option that you may be asked to use by the Woolich Racing Support Team. Please do not tick this option unless asked to by one of our Support Technicians.
After making changes to the the Start Log Configuration, be sure to click the Save button so that the settings are written to the Log Box.
If all options set to 0 or unticked, the Log Box will start recording data as soon as power is supplied (ie. when the key is turned).
After the Log Start Configuration has been set, you can disconnect the Log Box from your PC, and connect it to your Bike harness. You should then start the bike engine, and check the LEDs on the Log Box - the green and orange LEDs should flash quickly, and the red one should flash briefly every few seconds. This indicates the Log Box is receiving data, and recording it to the micro-SD Card.

| What is a Wideband O2 Sensor? |
A Wideband O2 Sensor (and Controller) is a sensor that you install in your exhaust to measure the Air Fuel Ratio (AFR) of your engine. The Wideband O2
Controller converts the signal from the sensor into an analog 0-5v voltage, which can be logged alongside other engine data allowing you to accurately tune
your fuel maps using a Woolich Racing Log Box v3 and the AutoTune feature in the WRT software. By matching up the AFR data with engine data from the ECU, we can adjust the fueling to a more optimal level, to potentially enhance the performance and reliability of an engine.

| Zeitronix Wideband O2 Installation |
A Wideband ozygen (O2) Sensor (and Controller) are used to measure Air-Fuel Ratio (AFR) of your engine which allows you to tune the Fuel Maps in your ECU using AutoTune in the Woolich Racing Tuned software.
Modern engines measure the amount of oxygen (O2) in the exhaust gas coming out of the engine, this information is then used to calculate the Air-Fuel Ratio (AFR) which the ECU then uses to control the amount of fuel delivered to the cylinders. Most bikes have a Narrowband O2 sensor installed from factory which only has a limited range of AFR readings (about 14-15 AFR), this is only really applicable to cruising conditions and does not allow users to tune their engine to achieve more performance etc.
Wideband oxygen (O2) sensosr allows measurement of AFR in the range of about 10-20 which covers the entire operating range of a conventional engine. Wideband sensors are then a valuable tool for tuning fuel maps to achieve a specific goal (eg. better fuel efficiency, lower emissions or more power).
Woolich Racing sells Zeitronix Wideband Sensor kits to allow these to replace the Narrowband sensors on many bikes, which allows the full advantages of the AFR and Autotune capabilities to be realised.
This video details how to install it a Wideband O2 Sensor onto your bike.

| How do I connect a Wideband O2 Controller to my ECU? |
The Log Box Pro, Log Box v2 and Log Box v3 all have a reverse RJ12 (telephone-style) connector which allows a direct digital connection to the Zeitronix Wideband O2 Controllers. When you purchase a full Log Box or Log Box Pro package for your bike you will receive an RJ12 cable in the Installation Kit. You just plug the RJ12 cable into both the Log Box and Zeitronix Wideband O2 Controller (ZT-3).
Note that the RJ12 cable that we use to connect to the Wideband O2 Controllers is not an actual phone cable as it has a special pin out (crossover cable). The connectors on the ends of the cable are shown here for reference: 
The Log Box v1 requires the 0-5v signal from the Wideband O2 controller to be wired into a pin on the ECU. The wideband is connected to the pin on the ECU that the stock narrowband O2 sensor connects to. You can simply cut the stock wire close to the ECU plug and solder the Wideband O2 analog 0-5v wire to the wire coming from the ECU. Or alternatively you can utilize the stock O2 sensor harness.

| Assigning AFR Oxygen (O2) Sensors to Cylinders |
A Wideband O2 Sensor (and Controller) is a sensor that you install in your exhaust to measure the Air-Fuel Ratio (AFR) of your engine. The AFR tells us useful information about the combustion process and is commonly used to tune the fuel maps on a bike. The Wideband O2 Controller converts the signal from the sensor into an analog 0-5v voltage, which can be logged alongside other engine data allowing you to accurately tune your fuel maps using a Woolich Racing Log Box v3 and the AutoTune feature in the WRT software.
Many bikes have a single exhaust so measurement of AFR can be done with a single oxygen sensor, a Zeitronix Zt-3 sensor and controller kit will work well in this situation. Some bikes have multiple exhaust pipes and it may be desirable to tune individual cylinders. This can be done with a single sensor and moving it between the exhaust pipes, or by using multiple sensors and installing them into specific pipes. Both of these scenarios require that we define the location of the sensors in the WRT software, the AFR readings will then correlate to the correct cylinder. The configuration of AFR sensors is done in the main 'Settings' window under the tab 'Cylinder AFR' as shown below:  This setting is used to link the correct AFR sensor to the cylinders that it is sampling, for Autotune, Engine Data, etc. If you have 1 x Zt-3 connected and it is sampling all 4 cylinders (O2 sensor is fitted after all 4 headers join into 1 pipe), then you would set the AFR for all 4 cylinders to AFR1.
This setting also allows the use of 2x Zt-3s such as a Ducati V-Twin, in this case you would set Cylinder 1 to AFR 1, and Cylinder 2 to AFR 2.
On a Ducati V4 with a sensor fitted to the front, and rear 'banks', you would set Cylinder 1 and Cylinder 2 to AFR 1, and Cylinder 3 and Cylinder 4 to AFR 2.
It is also possible to connect 2 x Zt-4s (Zt-4 is a dual-AFR sensor model) with 1 sensor in each header pipe, and map each AFR input to a single cylinder.
To connect more than one Zt-3 to a Woolich Racing Log Box, you will require a special data cable splitter.

| Do you warranty Wideband O2 Sensors? |
A Wideband O2 Sensor (and Controller) is a sensor that you install in your exhaust to measure the Air-Fuel Ratio (AFR) of your engine. Wideband O2 sensors are considered a consumable part that deteriorates during normal use. We only offer a warranty on Wideband O2 sensors if they fail when first connected as new. If the Wideband O2 sensor has been used then we are not able to warranty it. These Support Center articles may also be of interest to you:

| Can I use the Narrowband O2 Sensor that came stock with my motorcycle instead of a Wideband O2? |
It is not possible to use the stock narrowband O2 sensor on a bike for tuning with WRT, as the AFR measurement range is simply too narrow to use effectively for tuning purposes. We sell Zeitronix Wideband products that you can use to install onto the bike to measure AFR (Air-fuell ratio). Note that the wideband sensors (M18 threads) are larger then the narrowband sensors (M12 thread). You will then need to either weld a wideband bung into your exhaust, or purchase an exhaust that comes with a wideband bung pre-installed. We do also sell a Narrowband to Wideband O2 Adapter that screw into the stock narrowband bung on the bike, however we advise using the aforementioned solutions first, as they provide more accurate AFR readings. Some dyno-tuning professionals use sniffer pipes to insert into the back of the exhaust which does then not require modification of the exhaust to install the wideband sensors. Some bikes (eg. BMW S1000RR) do come with wideband sensors as stock, these can be used for tuning purposes through the 'Target AFR' maps in the ECU. These Support Center articles may also be of interest to you:

| Fast Baud Data Logging |
Fast Baud Data Logging (Fast Engine Data) can be enabled in Advanced Settings for some Suzuki Models.
This increases the speed of communications between the ECU and the computer when in Engine Data mode or when using the Log Box to log Engine Data from the ECU.
The Baud rate of communications is increased from 10,400 bps to 50,000 bps. (bits per second) (An almost 5x increase in data resolution over the factory data speed)
Note: The Suzuki Diagnostic Software will not be able to connect to the ECU if you have Fast Baud Rate enabled as it will try to connect at the default 10400 bps. If you would like to connect the SDS software remove the check in the Fast Baud Rate checkbox in Advanced Settings and flash the ECU with the changes.
