How do the plugs look? That's a real rich cruise area, and running that rich all the time may not be keeping the plugs clean which might impact responsiveness. Also, have the plug wires ever been changed. If not go for a new set of high performance wires.

OK, I have a newb question....
I recently had a S&S 124 installed in my '14 Breakout. I own a Power Vision for the bike.
The bike runs great. However, when it came time to tune the engine the shop that did the work did not use my PV. Instead, they used a H-D Screamin' Eagle tuner because that is what they are most familiar with.
My question is this - now that everything is done and the bike's on the road, can I use my PV to tweek the tune that's on the bilke now?
The bike is running great so I have no desire to mess with it. I'm just wondering if it's possible.

In WinPV get the tune you just saved to a slot, WinPV will open the tune with a name of untitled.pvt . Select File - Save as - and give the tune a descriptive name.
Then open the tune you just saved to edit / save / send to the Power Vision.
How to use Auto Tune Basic, Auto Tune PRO, & Target Tune Auto Tune with Dynojet Power Vision PV-1 and PV-2
Choose Tune to enable Auto Tune
Choose Tune to enable Auto Tune
- Turn Ignition switch and Run switch to ON position. Engine not running
- From main screen select PROGRAM VEHICLE then touch ACCEPT
- Choose AUTOTUNE to to enter the main Auto Tune screen
- To enable Auto Tune select ENABLE AT which brings up the Tune Manager
- 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.
- Once tune has flashed to your ECM select OK and turn the ignition switch to the off position for 20 seconds.
- Auto Tune is now enabled and you are ready to start your first Auto Tune session.
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.

You can use WinPV to get your tunes from the Power Vision and save them to your computer. (save using a unique name)
When you "get" a tune from the PV in WINPV it is opened with a file name of untited.pvt ( use "save as" using a unique name)
You can then use the WinPV software (under the PowerVision menu) to delete and send tunes to the PowerVision selecting the Slot to send them to.
If the Slot you select has a tune already it will be overwritten on the PV.
You can download the WinPV software user manual from DynoJet:

Question: when I got PV from FM, EITMS was turned off in the tune I loaded. Now after 2 years, EITMS mysteriously was turned on. I let H-D Dealer service the bike with routine maintenance. So the question is has my tune been changed? If EITMS is turned off in tune file, can it be activated normally or should that feature be inoperable?

That will read the tune in the ECM and allow you to save it in a slot on the PV (I believe it says "copy of current").
Connect the PV to your computer and get that tune from the PV.
Compare it to the tune you last flashed.
