The Power Vision is a new flash tuning solution that can meet the needs of any Delphi
ECM equipped Fuel Injected Harley-Davidson. Whether you are just looking to improve
the performance and fuel economy of your completely stock motorcycle, or you are
running an all out drag bike the Power Vision is the most flexible and powerful
flash tuner in the world. The Power Vision uses reflash technology to change the
parameters inside the stock ECM (Engine Control Module) that affects the way the
engine will run. It can be as simple as using one of Dynojet’s pre-configured calibrations,
or you can create a custom tune using the WinPV software.
The Power Vision is intended for Harley-Davidson Fuel Injected Motorcycles with
a Delphi ECM. This includes the 2001-Present Softails, 2002-Present Touring, 2002-Present
V-Rod, 2004-Present Dyna and 2007-Present Sportsters. The Power Vision offers the
latest flash tuning technology, data logging, and other industry exclusive features
for today’s high performance EFI tuning market.
The Power Vision will deliver a calibration (tune) to your Harley’s ECM that contains
the proper data for optimized performance and peak efficiency throughout the operation
range. You can mount the Power Vision on your bike and display the J1850 data (stuff
like knock, engine temp, spark advance, inlet air temp, etc) on one of many gauge
screens, and each gauge has a user configurable alarm to warm you in the event that
a parameter is nearing a potentially unsafe value. If you have a Dynojet Wide Band
2 or Auto Tune system, you can simply plug it in and add insightful wide band data
to the channel list. Power Vision also allows you to log the data in the event you’d
like to analyze this vital information after your ride is complete. You also have
the ability to check and clear ECM DTC’s (diagnostic trouble codes), and reset adaptive
No, a computer will not be needed to load one of the pre-configured calibrations,
or a copy of the original calibration into your motorcycle. You can even edit the
tune directly on the device without touching a computer. The list of available parameters
to edit directly on the Power Vision is limited, but it’s extremely handy for in-field
calibration changes. If you want to make adjustments to the calibration beyond what
can be done directly on the Power Vision, or if you are an experienced tuner looking
to maximize the effectiveness of your tunes, then you will need a computer with
Microsoft Windows operating system (XP, Vista, or 7) in order to use the WinPV tuning
application (which is included free).
The Power Vision connects to your computer using the included, standard USB to Mini
The Power Vision will only be able to tune one motorcycle (flash it as many times
as you like). It can be connected to other motorcycles to monitor / log data, check
and clear DTC’s (diagnostic trouble codes), and reset adaptive learning.
No, as everyones’ mounting needs will be different. The Power Vision uses the AMPS
four bolt pattern, so it can be mounted using many of the mounting solutions readily
We have partnered with Techmount to ensure that you can buy the mount that fits
your needs. Please follow the banner link below to access the Techmount website.
No. You can remove the display and your bike will run with the last tune that was
sent to the ECM.
The Power Vision is weather resistant. We recommend removing the Power Vision before
washing the motorcycle.

AutoTune needs to run long enough to gather information to make adjustments (20
minutes to 10 hours). You need to ride the bike long enough to hit all of the areas
you plan to ever ride the bike (rpm & throttle position). Once you have run the
bike awhile, you should have gathered enough data to adjust your tune. It would
be better to make multiple short rides, stopping to apply the AutoTune information;
than it would be to make one long ride. Each AutoTune session should be built on
the last session.
QuickTune is a simple way to make adjustments to the tune in your bike without using
a personal computer. In QuickTune you can make adjustments to a number of settings,
common ones are idle speed, rev limit, fuel and ignition timing. QuickTune can be
found on the Power Vision under Program Vehicle.
This will vary depending on how close the base tune is to your bike setup, and whether
you are using AutoTune Pro or Basic. A tune created with exactly the same components,
should only need 2-3 AutoTune sessions with Pro or Basic. A tune that was created
with only similar components would need more AutoTune sessions. AutoTune Basic will
need more sessions than Pro because the stock narrowband o2 sensors used in Basic
will only “read” a fairly small range, about 14.2 – 15.2. AFR values outside of
this range will only show as rich or lean. AutoTune Pro, using wideband o2 sensors,
will see AFR values between about 10.0 – 18.0. Therefore it takes less sessions
to make the needed adjustments.
The kits you need are technically the same as the AT-100 that's used with our popular
Power Commander, but these new Power Vision specific kits include a longer CAN cable
to connect the Auto Tune to the Power Vision, and also a Y-splitter to make power
/ communication a plug-n-play affair.
You’ll need one of these kits:
AutoTune Basic: (Only works on bikes with factory O2 sensors) Uses the bike’s stock
narrowband o2 sensors Works well as long as the base tune is fairly close to the
bike setup Works well for completely stock or lightly modified bikes No need to
drill holes and weld o2 bungs in head pipes AutoTune Pro: Uses Dynojet’s AT module
and two wideband o2 sensors Works well with any base tune Works well for highly
modified bikes Need to have two 18mm Dynojet o2 sensors in the exhaust
Dynojet supplies industry standard Bosch 18mm wideband o2 sensors in our AutoTune
kits. 12mm wideband o2 sensors are not readily available. To use the AutoTune module,
18mm bungs need to be welded into the headpipes and the 18mm sensors need to be
inserted into these bungs. The stock 12mm o2 sensors can be left in the exhaust
pipe for use after the Autotuning is complete. Dynojet has tested a few of the 12mm
to 18mm adapters and found them to not work correctly.
No, the WinPV software will be updated automatically at no charge when you run the
update client on your computer.
There are three types of tunes that you can deliver to your bike: pre-configured
tunes (loaded on the device from Dynojet), custom tunes (loaded or emailed to you
by a custom tuner), or you can use a copy of your original (The tune file that is
saved to the Power Vision when married to the ECM) tune to tweak. The Power Vision
will be pre-loaded with a large selection of pre-configured calibrations for bikes
with basic upgrades (intake and exhaust), as well as tunes for bikes with modified
engines (increased displacement, cams, head work, etc). As new calibrations are
developed, they will be automatically uploaded to the Power Vision through the update
client feature of the WinPV software……Just plug in the USB cable and select “Update
Client”, choose the update, and we do the rest. The Power Vision holds up to 6 tunes
(any combination of the 3 types) for you to choose from at your convenience, and
these can be replaced as many times as you like with updated tunes.
Dynojet has created a number of pre-configured tunes for various bikes; but there
no way to have a perfect tune for every possible combination of aftermarket parts,
or rare bikes like CVO’s. What you want to look for when selecting a tune is similar
components. If the aftermarket components have similar airflow, a tune created for
each would be very similar. All of the tunes we have built are located on our website,
and will be on your Power Vision if the tune database is up to date. If we do not
have a tune listed that is a close match for your bike because you have aftermarket
cams, etc, then you can request a tune to be built for your setup. Just send an
email to email@example.com and list the bike and all of the modifications. We will
build you a tune for the components listed and email it to you.
Dynojet works around the clock building calibrations (tunes) for different combinations.
If we don’t have a tune that a good fit for your bike; you still have options.
You can import a Power Commander map to most 2007 and older bikes, and some newer
than 2007 bikes. To import a map, first you need to download a Power Commander map
and save it someplace you can find it. Next, you want to retrieve the original tune
from the bike, and save that tune to a slot in the Power Vision. Next, connect the
Power Vision to your computer, open WinPV, and then select Get Tune. Select the
slot you saved the original tune. Now the tune is open in the WinPV software. Next,
select File, Import Power Commander Map. Find the map you saved earlier, and Open
it. The software will import the Power Commander map, and modify the Original tune
with those values. Now, just Send Tune to put that modified tune on a slot of the
Power Vision. Lastly, connect the Power Vision to the bike, and flash the ECM with
The best way to self modify a tune for a bike is to run AutoTune. Running AutoTune
on the Power Vision will make adjustments to the tune for your bike, in your environment.
Once the AutoTune has been run, if you are still having problem areas, you may want
to use QuickTune to make adjustments to the tune to address the problem areas. Both
AutoTune and QuickTune can be found under Program Vehicle on the Power Vision main
When a Power Vision is married to a bike, a copy of the tune in the ECM is saved
in a hidden slot on the Power Vision called Original Tune. To retrieve this tune,
with the Power Vision plugged into the bike, go to Program Vehicle/Load Tune/Load
Copy/Load Copy of Original. Click Ok. Select one of the six custom slots, and save
the Original tune there. When this step completes, exit out of the menu. With the
Original tune in a custom slot, you can connect the Power Vision to your personal
computer and use WinPV to Get Tune. The tune should be named “copy of Original tune”.
Once the tune is open in WinPV, you can go to File, Save As. Give the tune a name
and click Save. The default directory is My Documents/Power Vision. The Original
Tune from the bike is now saved on your computer.
Yes, the Power Vision can be tuned by a professional using a dynamometer. The bike
is strapped down on a dyno, and air fuel ratio is measured in the exhaust pipes
at various rpm/loads. Fuel and ignition timing are adjusted to achieve the best
running motor. This information is saved in the ECM of the motorcycle. For a list
of Certified Power Vision Tuning Centers, click here.
First you need to move the attached tune from the email, to a place on your computer
where you can find it. The desktop would be a good place. Once you have the tune
on the computer desktop, just open WinPV, and then select Open tune. Navigate to
where you saved it, and select the tune that was sent. Click Open. Now the tune
should be open in WinPV. With the Power Vision connected to the computer, click
Send Tune. At the Custom Tune Slot, select a slot to accept the tune. Click Ok.
That tune is now in the selected slot. Disconnect the Power Vision from the computer,
and connect it to the bike. Key on, run switch on, on the Power Vision menu select
Program Vehicle/ Load Tune/Custom Tunes. Highlight the custom slot the tune was
previously saved, and press Select. Continue through the remaining steps to send
the emailed tune to the ECM of the bike.
The Power Vision hardware has never changed; all new features and tunes are available
to every Power Vision made by running the PV Update Client. To run PV Update Client,
on your computer go to Programs/Power Vision/PV Update Client. Once you open the
PV Update Client, your computer and Power Vision items are compared to the latest
versions on our website. If the Installed version is different than the Latest version,
just select the outdated item, and click Download & Install Selected Updates. Once
all of the items are updated, your Power Vision is the same as one made today!
Log Tuner is an easy to use program developed by Dynojet to take data logs from
your Power Vision and generate a tune specifically for your bike. You don't need
to have a vast understanding of the Harley EFI system to use Log Tuner; we’ve made
tuning your bike easier than ever with sem-automated fuel and spark advance corrections.
Log Tuner can process data generated from the vehicle’s ECM and stock sensors (Auto
Tune Basic – no extra kits or parts required), or for the best results and the ability
to tune like a pro, you can add a Dynojet Auto Tune kit. The Auto Tune kit will
provide data that will allow you to tune ALL the operating ranges of your bike,
from idle and cruise, to higher loads and wide open throttle (Auto Tune Pro).
The Power-Vision does come the WinPV tuning software.
Lambda in reference to the Power Vision is a measurement of oxygen in the exhaust.
Lambda is similar to Air Fuel Ratio, but is independent of fuel type. An AFR for
pump gasoline of 14.64:1 (stoichiometric) is equivalent to lambda of 1. This is
where an engine will generally produce the best fuel economy, and produce the least
amount of harmful emissions. An AFR of 13:1 or lambda of .89 will generally produce
the most power and torque.
VE or Volumetric Efficiency is a measurement in percentage of efficiency that an
engine can move the air/fuel into and out of the cylinder at various rpm and throttle
positions (or manifold absolute pressure, MAP). This table is influenced by the
engine displacement, camshaft, head design, exhaust, and air filter. In theory a
value of 100 would equal the volume of the cylinder, but efficient design allows
values greater than this. The maximum allowed value in any cell is 127.5. To increase
fuel make the values larger, to decrease fuel make the values smaller.
On the Power Vision go to Datalog/Datalog Settings/Signals. On this screen highlight
Manual, and then press Select. On the next screen you will see the field selected
to log currently. To add more fields, press Add. On the next screen highlight the
field next to Signal. Next, select Vehicle to choose any channel from the bike ECM;
select Dynojet if you want to log data coming from an AutoTune module. On the next
screen select the field you want to log, and then press Ok, Ok. Once you have all
the fields you want to log, press Exit. When you start logging on the Gauges screen,
the channels selected will be logged.
To setup live gauges to view, on the Power Vision go to Datalog/Gauges. From this
screen you can scroll thru the available gauge setups by pressing the Left or Right
arrows. Once you have a Gauge screen you like, you have to select the fields you
want to see. Just press None, on the next screen select None. On the following screen
select Vehicle to choose from ECM channels, or choose Dynojet to choose from channels
from the AutoTune module. On the next screen select the channel you want to display
on that gauge field, and then press Ok, Ok When you have selected all of the channels
you want to see, just press Exit.
Most of the time we have seen this type of problem, it has been the cable running
to the Power Vision picking up interference from a coil or spark plug wire. Rerouting
the cable away from these items usually fixes this problem.
A naturally aspirated engine, running on pump gasoline will normally make the most
horsepower at an AFR of about 12.8 – 13.0. An AFR of about 14.6 will produce the
best fuel economy. Dynojet normally creates tunes with AFR’s of 12.8 at high load/rpm
areas; AFR’s around 14.6 at low load areas; and AFR’s between those numbers at other
