Dynojet Power Vision Target Tune Installation - 3
PRODUCT OVERVIEW
The Dynojet Target Tune accessory for Power Vision is a product that can add
a new dimension to your Harley-Davidson’s® ECM.
When paired with a Target Tune specific calibration flashed by a Power Vision,
your ECM will run closed loop fuel control based on wideband O2 sensors installed
into the exhaust, rather than the stock narrowband O2 sensors. The Power Vision
delivered calibration changes the coding in the ECM to “understand” the wideband
signal (from Target Tune) and allows the ECM to accurately achieve the target AFR
specified in the commanded air/fuel ratio table of your ECM’s tune. The ECM also
does this at all available engine ranges (not just light throttle cruising speeds).
Dynojet has evolved the OEM closed loop, adaptive fuel control system on your
Harley to meet the needs of performance enthusiasts.
Key Features:
• Allows the factory ECM to interpret and use wideband O2 sensor signals*
• Target fuel table from the calibration / tune is achieved in real time
• Retains OEM closed loop, adaptive fuel control strategy
• Learns and uses VE table corrections as you ride
• Does NOT interfere with dealer diagnostic / service tools
• Includes OEM style connectors to plug into factory O2 harness, either 2-pin
or 4-pin versions
• Fits 2006 and newer Harley Davidson® Bikes**
* Requires Power Vision Target Tune specific calibration
** ECM must be “closed loop capable” and have OEM wiring for O2 sensor circuitry.

1. Find a location to mount the Target Tune module
and secure it with the supplied Dual Lock strips.
You can typically find a place under the bike’s
seat or behind a sidecover to mount it. Be sure
to choose a location within the harnesses’ reach
of the diagnostic connector and stock O2 sensor
connectors.
The top of the ECM is typically a good mounting
location for most Touring models (Fig. B).

2. Install both of the supplied 18mm wideband O2 sensors into the exhaust system. (See “O2 Sensor Bung
Installation” section for guidelines if 18mm x 1.5 bungs need to be welded.)
3. Connect an O2 sensor cable to the front cylinder O2 sensor and route harness along the frame or stock wiring
harnesses going towards the Target Tune module.
4. Connect the other O2 sensor harness to the rear cylinder O2 sensor and route the harness along the frame or
stock wiring harnesses going towards the Target Tune module.
Note: Keep harnesses away from HOT and/or moving parts to prevent damage.
Note: If the supplied cables have different lengths, the longer cable should go to the front cylinder.
5. Connect the front cylinder O2 sensor harness to Target Tune module input #1 per Fig. A.
Connect the rear cylinder O2 sensor harness to Target Tune module input #2 per Fig. A.
Note: The harness can be cut to length if desired.
Note: To make inserting the wires into the module easier, first poke the hole with a paperclip or similar device. Also
tinning the bare wire ends with solder can help.

Locations” of the PV Quick Start guide for model
specific diagnostic connector locations.)
9. Route and connect the power lead from the Target
Tune module to one side of the Y-adaptor.
• 2008-2011 V-Rod models will require splicing of the
TT module’s power and ground supply wires; or for a
cleaner install with OEM style connections a power
extension lead (PN: 76950159) can be purchased
separately. If you are splicing the power supply,
the TT’s BLACK wire can go to a constant chassis
ground source such as the frame or the engine case.
The TT’s RED wire will need to go to a key-switched
12v power source.
• 2011 Softail models will require splicing of the

1. Find a suitable location to install the included
M18 x 1.5mm bungs on the exhaust system.
Note: Suitable locations may vary depending on
exhaust system. (See Fig. A and B)
2. Mount the bungs in a manner that reduces the
risk of moisture contamination to the sensor, as
condensation can build up in the exhaust system.
Ideally, the sensor should be between the 10
o’clock and 2 o’clock position on the pipe. A 10°
incline of the sensor above the horizon line should
be considered a minimum. (See Fig. C)
3. Mark the pipe where bungs will be mounted.
Note: Adequate room will be needed for the sensor
body and wiring.
4. Remove the exhaust system.
5. Drilling and welding of the exhaust system should
be done by an experienced welder/fabricator.
6. Reinstall the exhaust system.
The Target Tune kit has a built in function
which allows you to test the sensor accuracy
and condition.
1. Remove the sensors from the exhaust system and
hold in ambient air.
2. Verify the Target Tune kit has been powered up for
at least 1 minute and has a solid light.
3. Press and hold the function button on the front
of the Target Tune kit for 3 seconds to initiate the
test on sensor #1 and release the button once the
light begins to blink rapidly.
4. The LED light will blink rapidly, pause for a
moment, and then begin to flash a series of long
blinks before going back to solid. (You may get
zero blinks before going completely solid, which
would indicate a perfect condition if at or near
sea-level.)
5. Count the number of long blinks and refer
to the chart.
6. Initiate the test a second time to get results for
sensor #2.
7. Retest the sensors if there is any question as to
the purity of the air during the test.

Target Tune requires a special calibration to be flashed to your ECM in order to function
properly. You will need to send an e-mail request to [email protected]. Calibrations
submitted to make the Target Tune function properly can be:
• Copy of original or current tune
• Custom tunes
• Pre-configured tunes from Dynojet
The original tune that is being modified to work with Target Tune should be as optimal as
possible for the engine and modifications that you are using. This means if you have a very
unique or radical engine build, you may need to have a more optimal starting point tune
developed by other means before Target Tune can work effectively. This might be a tune
developed by a professional dyno tuner, a tune custom made by Dynojet staff, or a tune
developed by Auto-tune Basic or Auto-tune Pro methods.
Note: The Target Tune module can be used in place of the Auto-tune module when using the
Auto-tune Pro feature; but does require an additional CAN link cable that is sold separately
(PN: 76950427) and calibration changes.
If you’d like to use the tune that’s currently flashed to your ECM please follow these steps in
order to read it from your ECM:
1. Plug the Power Vision into the bike’s diagnostic port.
2. Turn the bike to the ON position (key ON, Run/Stop switch to “Run”, engine stalled).
3. Go to Vehicle Tools on the Power Vision.
4. Select Read ECM. Follow the prompts to read the ECM.
5. Turn the key OFF.
6. Remove the Power Vision and bring it to a computer with Dynojet WinPV software installed.
7. Connect a USB cable to the Power Vision.
8. After the Power Vision boots up and says “PC Link Mode Active,” launch the WinPV software.
9. On the menu bar, go to “Power Vision”, and choose “Diagnostic Test functions > Get ECM
Data from PV”.
10. Look for the “.stk” file (something like this…..10-FB4-JHMKORL.stk ).
11. Select the file and save it to your Personal Computer for safe keeping. (WinPV may have
already done this for you.)
12. E-mail the original .stk file to [email protected].
