Jan 09, 2016  I just installed my autotune a week ago and starting to mess with the tables slightly off the base map I was using. I can't go less than 13 at 80-100% or I get a couple pings when running a few degrees advance in that range (can only get 91 octane with no ethanol). All it means is the motor was running rich in the low rpm range, auto tune. Learn how to auto-tune to HD channels with X1. Learn how to auto-tune to HD channels with X1.

You accept the trim and the base map now has an 8 in that cell instead of a 5. The table of target A/Fs has not changed. The base map has changed.

How to use Auto Tune Basic, Auto Tune PRO, & Target Tune Auto Tune with Dynojet Power Vision PV-1 and PV-2

May 04, 2018  The AutoTune module creates the adjustments and stores them in a table called Trim. It is a good practice to accept these trims a few times (2-3), on a new install. When you accept the trims you will be moving the values generated by the AutoTune from the trim table(s), to the fuel table(s). Feb 15, 2014  Software shows all 3 devices connected with no errors. Both auto tune units light up and hold steady light. Everything appears to be working as it should except for no trims based on target AFR tables. No funky target AFR table values btw. I ran the PCV on this bike for a month or so before adding the auto tune and it works as advertised.

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 10 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.

AUTO TUNE QUESTION & ANSWER:

Q) How does Power Vision Auto Tune work?

A) Power Vision Auto Tune is an easy to use application within the product that automatically populates tune corrections to the VE tables in your Power Vision calibration. This process is done with the PV device while riding your bike, after an Auto Tune session the corrections are then exported and a new fuel map is created.

Q) what is the difference between Auto Tune Basic, Auto Tune Pro, and Target Tune?

A) There are several variations of Power Vision. Auto Tune Basic uses the factory O2 sensors on OEM O2 sensor equipped bikes, upon enabling Auto Tune Basic mode Power Vision setups up several parameters in the tune for maximum learning including setting the entire AF/Lambda table for closed loop operation. Auto Tune Basic works best for populating corrections in the light/mid load regions of the tune, Auto Tune Basic also populates corrections in the upper RPM/higher load regions as well, however due to the limitations of the factory O2 sensors which can only measure within the range of 14.3-15.0 AFR caution must be used when doing so. One advantage of Auto Tune Basic is that you are populating correction using the same sensors the ECM uses for closed loop. Auto Tune Pro uses Bosch 18mm wideband sensors and a dual channel Dynojet O2 controller, there are Auto Tune Pro kits for all models including bikes that are not equipped with factory O2 sensors. AT-Pro populates tune correction in open loop which are then exported back to your base tune. The Wideband O2 sensors can accurately measure 10.0-18.0 AFR and data is populated quickly over the entire RPM & load range of the calibration you are tuning. This works well with more extensive modifications as well as dyno tuning. In most cases with Auto Tune Pro when the tune is finished you will re-install your factory O2 sensors for closed loop or run both sets of sensors if you exhaust system allows such. Target Tune is the most powerful of the Auto Tune products, it uses a dual channel O2 controller with Wideband sensors, it is supported on bikes that originally came with factory O2 sensors. Target Tune uses 18mm sensors, the difference between Target Tune and Auto Tune Pro is that Target Tune is incorporated into the Delphi ECM and the system runs live closed loop using the wideband O2 sensors offering full time fuel control. There is also a Target Tune-Auto Tune application that allows you to populate measured tune corrections and apply them back to the base tune you are using. Fuel Moto EFI Store

Q) which Auto Tune application will work best for my application?

A) Choosing which Auto Tune application which would be best depends on your specific bike and modifications. Auto Tune Basic works best for mildly modified combinations, many have had great success tuning for cams and more extensive modifications, it really comes down to the accuracy of the base map. Auto Tune Pro works on bikes that did & did not not originally have factory O2 sensors and is capable of populating tune corrections for extensive modifications. Target Tune allows users to generate tune corrections using Bosch wideband sensors and also gives the big advantage of running live closed loop off these same sensors which are incorporated into the factory O2 harness.

Q) How many Auto Tune sessions are required to get an accurate tune?

A) It depends on the combination and overall accuracy of the base map. We generally recommend on starting with three, 20 minute tune sessions. Between each session you will export learned, create a new map in the Tune manager. For the following session enable this new map so you are working forward with the latest corrections.

Q) What do the various screens/modes do in Auto Tune?

A) The default screen represents Hits for a given cell and will display 0-99+, the second set of screens is the front/rear VE tables, the third set of screens are Corrected front/rear VE tables, the fourth and in many cases most helpful set of screens is front/rear VE +/- fuel % correction which represents the amount of fuel correction requested by Auto Tune that has been populated. You will generally want to get this within 5%, however this will vary based on relative conditions, fuel, etc. The final AT mode screen is hits screen that zooms in on the specific cells that are being populated.

Q) How do I know when Auto Tune is completed?

A)The biggest consideration is running quality and overall performance. For VE you will want to run Auto Tune or manually tune until the VE corrections and/or AFF/CLI values are within 5-7%, this can be determined within the Auto Tune Correction screen which can be accessed by selecting Mode or you can also put the maps in WinPv and compare the deltas. If you are within 5-7% this tells us that closed loop is only leaning on the O2 sensors for minimal adjustments. On the spark side of things you will look for minimal knock events in your logs or by monitoring your gauges, some light knock activity is generally normal. You however want to eliminate large areas on knock retard or if it is continually picking up knock activity in a certain area. You want your timing tables to work within the limitations on knock retard, remember the ion discharge knock system does not sense actual detonation, it senses the sudden increased in cylinder pressure that are generally associated with detonation.

Q)What is Cap or Scale and what should I select?

A) When you export your learned corrections with Auto Tune and it asks you to cap or scale this means that there is a cell or cells in the VE tables that are at or have exceeded the high limit of the VE table of 127.5. If you select Cap it will “cap” the cell(s) at 127.5 and correct the rest of the VE tables based on your Auto Tune data. If you select Scale it will raise the displacement constant (cubic inch) within the calibration and then normalize (lower) the VE tables. Choosing Cap or Scale will depend on not only the amount of cells that are maxed at 127.5 but also the load range they are located. If you have only a single cell or small cluster at 127.5 in most cases we would recommend capping, especially if the cells are in the lighter load or decel area. If you have a large cluster of cells that are maxed or of they are in the higher load or WOT areas you may need to select Scale. Some important considerations when scaling; you will want to have as much data as possible before selecting scale as the entire VE table will be changed and normalized for the difference in displacement. In some cases depending on the amount of correction and the data itself it may scale excessively, this can result in an abnormally high displacement constant and abnormally low VE tables. Generally speaking, most scaled maps on mildly modified motors should be within 10-15 CI of the actual engine displacement, however it not uncommon on extensively modified motors to end up the CI in the 140-150 range.

Q) What do I do when I am done using Auto Tune, can I just leave the bike in Auto Tune mode?

A) Auto Tune is an application designed to populate maximum data for tune correction, because various tables are changed and features are altered to better permit data collection it is not recommended to run in Auto Tune mode full time. When you are not doing an Auto Tune run session or when your tune is finished you will flash the final map and the ECM will operate normally. Also note you will not want to simply disable Auto Tune, you want to make sure you flash the map to the ECM.

What is Target Tune:

Auto Tune Accept Tables Online

Target Tune is an add on module for Dynojet Power Vision that uses a control module and 2 Bosch wideband AFR / Lambda sensors integrating them into the H-D Delphi ECM. 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, it is a plug in kit into the factory connectors. In order for the system to work, you must have a Target Tune enabled calibration flashed to your bike with the various edits required to make it work. Fuel Moto or a Dynojet technical representative can supply Target Tune enabled maps or make the necessary edits to your existing tune. Download cooking tycoon cheat.

So my ECM is now able to use wideband o2 sensors on the fly?

Yes, your ECM has now been configured to use wideband O2 data and use them for closed loop control based on the AFR/Lambda targets in your fuel table using short term & long term fuel trims.

What should I expect?

Your bike will perform better once the various thresholds to allow closed loop fuel control are met, things like engine temp, etc etc. It will run at the target AFR or Lambda defined in your calibration’s fuel table even if your VE tables are not perfect by using both short term & long term fuel trims.

Can I make changes to my tune?

Auto Tune Accept Tables For Sale

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

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

Yes. Fuel Moto or Dynojet will set up your fuel table for best results, but you can edit these values to suit your needs.

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

Absolutely, the Target Tune module works excellent for the AutoTune function and it has its own Target Tune-Auto Tune mode. When enabling Auto Tune you will select, “Dynojet Target Tuner Wideband Kit” when starting an Autotune session. The TT-Auto Tune application generates air/fuel corrections to the VE tables which can be exported back into the tune, once exported the tune reverts back to live closed loop operation. Instructions for the Auto Tune process can be found here.

How can I turn off Target Tune?

You can load a tune that doesn’t have Target Tune enabled (you will have to reinstall the factory O2 sensors), or you can use Quick Tune to turn off closed loop.

What is the adjustment range for Target Tune?

Target Tune calibrations are generally set up to 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. To watch live corrections (short term fuel trims) with your Power Vision you can view the channels Front & Rear Closed Loop Integrator (CLI), these are a +/- multiplier of the live fuel corrections as a %, for stored corrections (long term fuel trims) you can view Front & Rear Adaptive Fuel Factor (AFF). You can also monitor WBO2 for the Vehicle Signals for 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:
  Choose “Vehicle” from the “Select Signal Source” screen. Select WBO2 AFR Front and Rear, or WBO2 LAMBDA Front and Rear.

• Like any “closed loop calibration”, the Closed Loop Integrator (CLI-short term fuel trim) 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”. For example if a CLI value of 103 is reported, 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 learned values will move, or change much slower than the CLI. When the proper conditions have been met the ECM will generate long term/long term fuel trims (AFF). If you see a AFF value of 105 reported, that means the ECM has applied 5% to the respective front or rear cylinder VE table in order to achieve the target AFR or Lambda. Conversely, the value of 95 would indicate the ECM had to subtract 5% 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”

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. There are full instructions on the Auto Tune process located here

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.
