Power Vision CX: How to Update Your Firmware

150

Written by:

In this tutorial you will learn how to update the Power Vision CX using Dynojet’s Power Core Software.

 

Step 1: Go to www.dynojet.com/powervision. Put your mouse pointer over “Support,” to bring up the support menu. Move down and click the “Downloads” option.

Step 2: Click the “Select a Product” drop down menu; choose “Power Vision CX”.

Step 3: Download and install the Dynojet Power Core Software.

Step 4: Download and save the firmware file to an accessible location on your computer (i.e. your desktop, a downloads folder, or a dedicated folder). The file will come in a “zipped” folder. The actual firmware file inside (with a .dfu filename extension) will need to be extracted before you can use it. Open the file with Windows Explorer. Click “Extract all files”. Follow the on screen prompts.

Step 5: With your Power Vision CX plugged in to your computer or vehicle, check your firmware number on the device by going to DEVICE TOOLS>DEVICE INFO>ABOUT and you will see the device firmware build number. If this number matches the firmware version number on the downloads page, your firmware is up to date. If it does not match continue installing the latest firmware version.

Step 6: Launch the Power Core Software. In the Application Launcher, click TOOLS>MANAGE HARDWARE. The window Device Manager will open and you will want to make sure on the left side of the window that Power Vision CX is selected.

Step 7: On the right side click INSTALL FIRMWARE, locate the extracted firmware file previously saved to the computer (the .dfu file) and open it. The update process will begin.

NOTE: If it is the first time updating the firmware, USB boot loaders will automatically install and may cause the updating process to timeout and stop. If you get any error messages, reboot your computer and try again. Make sure you see the “Update Completed” message at the end.

Step 8: Make sure the message UPDATE COMPLETED is shown. If you see this message, your Power Vision CX firmware is now up to date and you are ready to flash.

Target Tune FAQ’s

1321

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.

clip_image002

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.

clip_image004clip_image006clip_image008

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”.

clip_image012clip_image014

  • 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.
