FP3 HELP, no green cells on Autotune
Introduction
One of the many benefits of the Fuelpak FP3 is the AutoTune feature. This feature allows users to precisely tune their motorcycle for their intake and exhaust combination, avoiding the costly and demanding dyno runs or the installation of additional equipment. AutoTune can also help international users tune their motorcycle for the specific fuel blends available in their area.
When to use it/not to use it:
AutoTune can be utilized where a Vance & Hines map is not provided or to further fine tune a specific intake and exhaust combination to the unique variations of an individual bike.
Most combinations can be cross referenced with one of numerous maps Vance & Hines provides. The AutoTune works best with an existing map from the Vance & Hines database. This will now utilize specifically tuned ignition tables, Accel Enrichment, Decel Enleanment, AFR (Air Fuel Ratio) Tables and Rev Limit changes, to facilitate calibrating the Volumetric Efficiency (VE) Tables. AutoTune calibrates the VE tables with a unique V&H developed algorithm for fast and accurate tuning.
How it works:
To understand how AutoTune works, the differences between calibrating a bike's ECM and tuning a motorcycle must be defined. The ECM knows what volume of air is flowing through the engine for the stock intake and exhaust systems. However, when the intake and/or exhaust systems change, the Volumetric Efficiency of the cylinders change. AutoTune properly calibrates the Volumetric Efficiency Tables by utilizing the high precision range of the the factory narrowband O2 sensors to target the optimum Air Fuel Ratio (AFR) of 14.4. When the bike is in AutoTune mode it monitors the difference of the O2 voltages above or below the 14.4 desired AFR. These differences are recorded, calculated and VE tables change. After calibration, the FP3 can change the AFR. For example, richer AFR can be selected for better power and engine running, or a leaner AFR in some areas during light loads and cruising for fuel economy.
While running AutoTune, FP3 is calculating VE Table/tables and other aspects of the ECM settings. Which comprise the tuning of the motorcycle. These changes are saved and not made in real time. Volumetric Efficiency ables are modified AFTER "Apply Learned Values" or "Finish" has been selected. Then flash the calibrated map to the ECM.
How to Use It:
Select a map to tune
When entering Autotune for the first time, you will need to select a map to start from. The maps listed are all the maps stored on your FP3. Choose the map and press continue.
Flashing the new map (what changes are made)
After selecting a starting map, the app loads this map to the autotune memory and prepares it for the autotuning session. Changes include setting the AFR table to closed loop everywhere and zeroing out the transient fueling. During the AutoTune process the Accel Enrichment and Decel Enleanment will be shut off to avoid erroneous readings. The overall riding experience is not optimized. This DOES NOT reflect the way the bike will run after the AutoTune tables have been populated with the learned values. This is only a temporary condition.
Recommendations for Best AutoTune Results
These changes are then flashed to the ECU (follow the on-screen prompts to complete the flashing operation). After flashing the Autotune map, the app presents a grid of white squares. You are now ready to ride and begin the tuning process. The bike will need to be warmed up to normal operating temperature (approx 200 deg F) before autotune will begin. As you ride, the squares will turn orange or green. White squares are completely unlearned cells. Orange indicates partially learned. Green squares are completely learned. Once a square turns green, the learning for that cell is complete and additional riding in that zone will not refine the learned value. You do not need to keep your phone on and the FP3 app active during the autotune process. However, if you have a way to display the screen while riding, it can be informative to see areas that are learned and what other areas you need to cover. The FP3 unit will need to be plugged into the bike for autotuning to occur. Do not be concerned if you need to turn the bike off - the FP3 will pick up the tuning process once the engine is restarted and the engine is up to temperature.
Riding recommendations (what to expect and what the map will look like. What you can and cant do in the app.)
When riding during the autotune process, you will want to cover as many different throttle angle and rpm combinations as possible. You will not want to use cruise control. Ride up and down some hills in addition to stop-and-go traffic and freeway miles. Avoid abrupt throttle changes so the FP3 can adequately sample each cell. Try to cover as many of the cells as is possible, but there is no need (nor is it even possible) to cover every cell. Most riders can get good results in three 30-45 minute sessions of riding. All cells do not need to be green to have a complete autotune session. Normal Autotune session will show mostly green with 25-30% orange. The shape of the colored cells in the Autotune grid should resemble a football shape. Low throttle positions/low rpm (top left) to high throttle positions/high rpm (bottom right). See below for an example (results may vary).
While the FP3 is in the autotune mode, you will not be able to access certain portions of the app. You will not be able to view/edit maps nor will you be able to search for a new map.
Once FP3 has learned a number of cells, you can apply or finish the autotuning session. When you first ride the bike in autotune be aware that the characteristics are often quite different so start out slowly.
Applying the changes
If you apply the autotuning values, a new map is created and flashed to the bike. Follow the on-screen dialogs during this process. After applying the learned values, the FP3 remains in Autotune mode and will continue to learn. The apply function should only be used if you will immediately be starting another autotune session. If you are done riding for the day or have completed your second autotune session you should complete the autotuning session by finishing the session.
Finishing Autotune
Finishing the Autotune session applies any learned values (just like in the apply process) and also returns the AFR table and transient fuel to their original values. This new, final map is then flashed to the bike (follow the on-screen dialogs to complete this process). FP3 is then taken out of Autotune mode. After the VE Tables have been calibrated and saved to the map, the AFR tables can be tailored to individual rider preference or better developed by dyno pros. The AFR tables of a Vance & Hines map have been set to a custom blend offering a combination of WOT performance and part throttle economy.
Sorry to hear you are wrestling stereo gremlins too...
It's always something..
What was supposed to be a $20k bike new back then..
And it has fiddy cent brackets in it.
Bastards..
I'll have it back together soon..
Couldn't find a cheap hardware store solution that I liked so I ordered the kit from chopperdave...
If it gives me anymore bullshit I'll light it on fire.
I won't let it win.
Lol
