How to use Auto Tune Basic, Auto Tune PRO, & Target Tune Auto Tune with Dynojet Power Vision PV-1 and PV-2

Choose the tune you would like to Auto Tune; touch to highlight the tune and then press SELECT. In most cases you will select the Fuel Moto tune we supplied.Next choose the appropriate Auto Tune mode. Touch and SELECT either BASIC if you are using the factory narrowband O2 sensors, PRO if you are using the optional Auto Tune Pro kit with wideband O2 sensors, or if you have the optional Target Tune kit select TARGET TUNE WIDEBAND KIT
Select CONTINUE to enable and flash the ECM for Auto Tune operation. The Power Vision sets up the tune in a temporary state for maximum data collection and correction generation.

Initiating Auto Tune
It is best to first get the bike to full operating temperature
Start motorcycle
Once motor is running go to PROGRAM VEHICLE>ACCEPT>AUTOTUNE
To start your Auto Tune session select DATALOG. This will bring you to the green histogram screen. From this screen the default screen is “hits” which will show how many times data is populated for a given cell. We generally want 10 or more hits for each cell (they will change color as they are generated). If you select the mode screen this will show you various tables, most helpful is front & rear correction which shows you the specific % fuel correction that has been generated. Note: you will not be able to reach all areas of the tune, this is normal.
You can now ride your bike, we generally recommend 20 minute tune sessions of mixed riding, try to hit as many RPM & load areas as possible. Note if your session is cut short you can restart the bike and go back to the Auto Tune green screen, select Datalog and continue where you left off. Correction data is stored until it is either exported or a different map is flashed to the ECM.

Saving & Applying Auto Tune corrections
Once you have completed your Auto Tune session before you shut the bike off select EXIT and then select EXPORT LEARNED. This step creates a new Auto Tuned map and allows you to place it in the Tune Manager. Do no overwrite the previous tune you were using, select a different slot. You now have an Auto Tune “corrected” tune in the tune manager. Note: Auto Tune maps are labeled in sequence. If you shut your bike off before you Export Learned that is OK as Auto Tune data is automatically save every 3 minutes.
To flash your Auto Tuned map go to PROGRAM VEHICLE>LOAD TUNE>CUSTOM TUNES and select the appropriate tune from the Tune Manager and press OK. When prompted “would you like to clear learned fuel trims” select YES. Once flash is complete turn off ignition switch for 10 seconds. You can now ride with your updated map.

TUNING TIPS:

Data & corrections are best generated in a steady state, try to be as smooth with the throttle as possible and get to as many RPM and load areas allowed. We generally recommend starting with three, 20 minute Auto Tune session for most applications. Between each Auto Tune session EXPORT LEARNED, then for the following session enable Auto Tune using the map you just created. This way you are always working forward with your corrections. It is also recommended to start the tuning process with the tune your bike runs best.

If you are using Auto Tune Basic understand it is using closed loop @ 14.6 AF, this is best suited to mild or moderate loads; a limitation of the factory narrowband sensors. If you are using Auto Tune Pro or Target Tune you can generate tune corrections over the entire operating range.

It is recommended with most combinations to set the minimum MAP pressure to 30KPA under SETTINGS as shown in the video below. This prevents overcorrection of the decel and transient region of the tune.

After you have finished your Auto Tune session you need to either flash the new tune or your previous tune from the Tune Manager. DO NOT select Disable Auto Tune or leave the bike in Auto Tune mode as the tune is setup for optimal data collection rather than drivability.
