Power Vision Firmware Update

Keep on Tuning!  Dynojet Power Vision supports the latest updates for H-D motorcycles with the new firmware level and tune database.

We just released a new firmware and tune database for Power Vision, firmware, and tune database Which means Power Vision now supports two new software levels for Harley-Davidson Motorcycles; 621 and 822.

Software level 621 is used on 2014 and newer Softail & Dyna 110” models.


822 is used on 2017-2018 Touring models.


Simply use the update client to manage the download and installation of the latest firmware.  Once updated you’ll be able to tune these new software levels using the original tune as the basis, or use 617 (for 621) or 723 (for 822) level calibrations in their place.  To avoid any voids in service, the Power Vision Tune License Program has also been updated and will support these new software levels.

We’ve been tuning 2017 H-D’s, have you?


Written by:

As mentioned in the last post, we started development on the new 2017 H-D models back on 8/23/17.  To date we’ve been through 7 different versions of firmware that are specific to the new models and the results have been great.  Thanks largely in part to our strong network of Power Vision beta testers; including shops, tuning centers, and otherwise savvy individuals that have been using our beta tool kit, we now have 82 calibration items supported in WinPV for software level 723!!

We’re busy developing tunes at this point, as are many of our technical partners.  We expect to make a public release on 9/26 and continue to build our tune database to support popular modifications.

As a side note, the Power Vision Tune License System does support the latest software levels…….give it a test drive if you’d like.  There’s not a more cost effective means on the market to tune H-D motorcycles.

Power Vision: 2017 H-D Support


Written by:

2017 PV

There are 2 new software levels that we’ve come across thus far, those being 723 (Touring) and 414 (Sportster, Street, Dyna…..except Dyna Low Rider S, which is 617).  We started reading these calibrations back on August 23rd and have been beta testing since.  A Power Vision loaded with the current, publicly released firmware will allow you to tune (and use the Tune License system) ALL 2017 H-D motorcycles EXCEPT those that use the 723 and 414  software levels.

Beta testing results thus far have been positive on the 723 and 414 software level bikes.  We continue to add additional tuning parameters to ensure the highest level of control possible.

Target Tune FAQ’s


Written by:

What is Target Tune? 

  • Target Tune is a product that uses a control module and 2 Bosch wideband AFR / Lambda sensors. It uses the existing closed loop, adaptive fuel control strategy in your Delphi ECM, but with changes made to the calibration to allow your ECM to use the wideband sensors. In order for the system to work, you must have a calibration flashed to your bike with the various edits required to make it work. At this time only a Certified Power Vision Tuning Center, or a Dynojet technical representative can make those edits.

So my ECM is now able to use wideband o2 sensors and fix-up my tune on the fly?

  • Yes, your ECM has now been transformed and is allowed to read and manage wideband o2 sensors, and more importantly, use them for closed loop control on your fuel table.

What should I expect?

  • Your bike will immediately run better once the various thresholds to allow closed loop fuel control are met, things like engine temp, etc. It will immediately run at the target AFR or Lambda defined in your calibration’s fuel table even if your VE tables are not perfect.

Once Target Tune is installed and I have the correct version of my calibration flashed, what do I do?

  • Enjoy the ride with newfound power and torque, and the satisfaction knowing you have the most sophisticated tuning solution available for Harley-Davidson motorcycles.

Can I make changes to my tune?

  • Yes, all the regular tuning parameters that are exposed to you in WinPV are still available.

So if I change the values in my fuel table, my bike will actually run at those AFR or Lambda values?

  • Yes. Your tuner, or Dynojet would have set up your fuel table for best results, but you can edit these values to suit your needs.

Why does Target Tune not seem to be working? Why I am getting errors on the bike after installing Target tune?

  • You have to be using the newest desktop software, firmware, and tune database for Target Tune to function. Using old versions of any of these will keep Target Tune from functioning.

Can I use the Target Tune module for the AutoTune process?

  • Yes, the Target Tune module will work for the AutoTune function. Be sure to select the correct mode, “Dynojet Target Tuner Wideband Kit” when starting an Autotune session.


Will Target Tune make adjustments in the tune that I can see?

  • No. At this point only those users with special credentials, like Certified Power Vision Tuners, can make the necessary calibration changes to make Target Tune function. That being said, unless you have these special credentials you will not be able to “see” the calibration changes in WinPV. Once the necessary edits are made to your calibration, and the Target Tune is fitted to the bike, you are ready to go. The ECM will use the information provided by the Target Tune system to make adjustments to the short and long term trim fields in the ECM of the bike, while you ride. These fields are not found when you look at the tune in WinPV.

How can I turn off Target Tune?

  • You can load a tune that doesn’t have Target Tune enabled, or you can use Quick Tune to turn off closed loop.

What is the adjustment range for Target Tune?

  • Target Tune can subtract 30%, and add 40% fuel to a tune. Your tuner can adjust these values if need be,

How can I tell if Target Tune is working?

  • At any given operating condition there is an AFR, or Lambda value the ECM is trying to achieve. Using the fuel table as a reference, you can simply monitor the real time AFR or Lambda on your Power Vision while riding, or create a datalog to verify. There are also other channels that can be monitored, or logged that would give you an indication that Target Tune is online and the ECM is using it accordingly.

How do I setup the channels?

  • Select “Datalog” from the main menu, then “Gauges”. Select the style of gauges you’d like to work by scrolling left or right. Tap the gauge to assign a channel, and the “Set Gauge Properties” dialog will appear. Tap the field that says “None” and then choose the source and the channel you’re interested in. You’ll also need to change from “Basic Signals” to “Advanced Signals” by tapping the “Change” button.


To monitor AFR or Lambda from the Target Tune:

  • Remember, with Target Tune fitted to the bike the wideband values are now part of the ECM’s internally calculated channels (Signal Source = Vehicle). When using Autotune Pro, the wideband values are external to the ECM and simply sent via the Dynojet CAN cable to the Power Vision (Signal Source = Dynojet).
  • Choose “Vehicle” from the “Select Signal Source” screen. You’ll see “WBO2 AFR Front” (and Rear), along with “WBO2 LAMBDA Front” (and Rear).


  • Like any “closed loop calibration”, the Closed Loop Integrator (CLI) should be active during normal riding conditions. This value should constantly swing up and down constantly, where the value of 100 is the “pivot point”. If you see a value of 103, that means the ECM had to add 3% to the respective front or rear cylinder VE table in order to achieve the target AFR or Lambda. Conversely, the value of 97 would indicate the ECM had to subtract 3% to the respective front or rear cylinder VE table in order to achieve the target AFR or Lambda. To view these channels, assign them to a gauge. You’re looking for “Front Closed Loop Integrator” and “Rear Closed Loop Integrator”.


  • If you have Adaptive Fuel enabled in your calibration, then you should also notice Adaptive Fuel Factor (AFF) change over time. These values will move, or change much slower than the CLI. Similar to the CLI values. If you see a value of 103, that means the ECM had to add 3% to the respective front or rear cylinder VE table in order to achieve the target AFR or Lambda. Conversely, the value of 97 would indicate the ECM had to subtract 3% to the respective front or rear cylinder VE table in order to achieve the target AFR or Lambda. To view these channels, assign them to a gauge. You’re looking for “Front Adaptive Fuel Factor” and “Rear Adaptive Fuel Factor”

clip_image016 clip_image018

Do the Adaptive Fuel Factors get committed to my calibration?

  • No, however they are used by the ECM to calculate the final amount of fuel to be delivered at a certain operating condition. The AFF values are used by the ECM until you clear them via the Power Vision function “Reset Fuel Trim”. These values are effectively applied to the base VE tables in your calibration by the ECM, however they are NOT committed to the calibration itself. To properly “fix” your calibration, you would need to use the Autotune process and select the proper mode (“Dynojet Target Tuner Wideband Kit”).

How does Target Tune AutoTune process work?

  • Utilizing the Target Tune AFR data and other data from the H-D OEM data bus, the Power Vision can automatically fix the deviation between the AFR or Lambda as defined in the fuel table of your calibration and the actual AFR or Lambda by adjusting the VE tables. The data is learned in real time, but processing the data and adjusting the tune is done in an “offline state” (key on/engine off). After the data is collected, the Power Vision can process the data, correct the tune, and then re-flash the corrected tune into the ECM. You’ve effectively corrected the VE tables to ensure the AFR or Lambda you ask for (in your calibration) is what you get (as measured by the wideband o2 sensors). Once you exit the Autotune mode you’ll be back to using your full-time, Target Tune closed loop calibration.

What happens if there is a problem with Target Tune?

  • The OEM diagnostic system is still fully functional, and in the event there was an issue a DTC would be set. You can use the Power Vision to read the DTC like normal. If the module, sensor, or harness were to fail the ECM would transition into open loop, just like if your OEM narrowband sensor were to fail.
