REFLASHING THE OE RADIO
BC-DSPL-HD2
• Reflashes the OE radio curve to a flat response
• Water Tight Saddle Tramp Case
• 31 Band graphic equalizer or 5 Band parametric EQ per channel
• Pre-wired for quick installation when retaining the OE radio
• BC-9715 harness with pre-wired inputs and outputs
• Independent equalization for all outputs
• Independent crossover for all outputs
• Selectable slope (12, 24, 36, or 48db per octave)
• Signal Delay
• Settings adjusted via Bluetooth
®
in a smart device application (tablet or mobile phone),
compatible with both Android™ and Apple
®
devices
• Read, write, and store configurations for future recall
• Password protect feature available in the mobile app
• Micro-B USB updatable
IMPORTANT: This product is not a reflash
tool. The BC-DSP interface stores the OE
radio’s serial number and locks to the
motorcycle vehicle identification number
(VIN) during the programming process.
To move the DSP interface to a different
motorcycle, you must return the original
radio to the OE curve before uninstalling.
This process can be repeated a total of
(3) times before the DSP will no longer
function. Both the Serial number and VIN
numbers are stored in the DSP and cannot
be removed or reprogrammed, except
by the manufacturer. Each DSP that is
returned will be decoded and evaluated.
If Metra suspects inappropriate use, a
credit will not be issued.
BC-9715 Harness
• Add an amp harness 2014-up HD with OE radio and fairing
• Provides pre-terminated input and output wires
• RCA output harnesses included
• Pre-wired rear speaker output, used with BC-9720 backbone harness (sold separately)
• Universal for all amps
• Wire covered in protective cloth tape
Reflashing the OE Radio
Stock non-amplified Harley Davidson’s radios use pre-programmed crossover and equalization
settings that are locked into the OE radio. These setting can’t be adjusted without reflashing your
OE radio. Within the Vehicle Selection page of the AX-DSP-XL app you can reflash your OE radio
to output a flat frequency response curve.

1. Unsnap the Cap from the case. Insert the
overmolded gaskets from the BC-9715
harness into the respective opening in
the front of the Cap, making sure the
grommets are properly seated.
2. Slide the DSP board out of the case and
plug in the 16 and 20 pin connectors.
3. Reinsert the DSP board into the case and
snap the Cap into place. The arrows on
the Cap should be pointed toward the
Saddle Tramp logo on the case.
4. Find a secure mounting location for
the DSP case. It is recommended that
the cap be installed facing down. The
Zip-tie Mounts on each side of the case
can be used to secure the DSP into place.

BC-9715 HARNESS INSTALLATION
1. Unplug the OE radio connector and
install the BC-9715 t-harness. BC-9715 t-HarnessBC-9715 t-Harness
OE Connector removed from radioOE Connector removed from radio
2. The installation of the pre-wired harness is designed to work with multiple styles of aftermarket amplifiers with different
types of inputs and outputs. Both input (white connectors) and output (black connectors) wires on the BC-9715 harness use
Molex terminals that are pre-crimped onto the speaker leads; loose Molex connectors are included to allow the user to pin the
connectors accordingly.
If the amplifier uses Molex Micro Fit connectors for the inputs and outputs, simply match the amplifier’s speaker configuration
and plug them in using the provided connectors.
If the amp uses RCA inputs, pre-terminated Molex connectors with RCAs already wired are provided. The option to hardwire the
speaker inputs and outputs would be the final option.
3. To get battery power and ground wires up the backbone of the motorcycle use Saddle Tramp’s BC-9703 harness. (Sold
separately)
TIP: If you have pinned the Molex Micro Fit connector improperly, you will need to use a Pin Extraction tool. (See page 22 for
Troubleshooting tips)

SETUP INSTRUCTIONS
The Saddle Tramp Digital Signal Processor (DSP) uses the AX-DSP-XL app to setup, program, and
control the setup of your DSP.
SETUP INSTRUCTIONS: The General Information tab for installing the interface.
BLUETOOTH CONNECTION
SCAN: Press this button to start the Bluetooth pairing process, then select the interface once it is
found. “Connected” will appear in the top left corner of the app once it is paired.
Note: The interface must be powered during this process.
DISCONNECT: Disconnects the interface from the app.

CONFIGURATION
IDENTIFY: Click this button to confirm that the interface is connected properly. If so, a chime will
be heard from the front left speaker.*
* Only installations where the interface is connected to a front left speaker.
RESET TO DEFAULTS: Resets the interface to factory settings. During the reset process the
amplifiers will shut off for 5-10 seconds.
VEHICLE TYPE: Select the vehicle type from the drop down box, select EITHER
EQUALIZER (EQ) TYPE: User has the option of optimizing the motorcycle’s sound quality
with a Graphic or Parametric equalizer.
LOCK DOWN: Click this button to save the selected settings.
Attention! This button must be selected before closing the app or cycling the key;
otherwise, all settings will be lost.
SAVE CONFIGURATION: Saves the current configuration to the mobile device.
RECALL CONFIGURATION: Recalls a configuration from the mobile device.
ABOUT: Displays information about the app, vehicle, interface, and mobile device.
SET PASSWORD: Assign a 4-digit password to lock the interface. If no password is desired,
use “0000”. This will clear out any currently set password. It is not necessary to lock down
the interface when setting a password.
Note: A 4-digit only password must be chosen; otherwise, the interface will show
“password not valid for this device”.

OUTPUTS
Output Channels
Location: Location of speaker.
Group : Used to join channels together for simple equalization.
Example : Left front woofer/midrange and left front tweeter will be considered simply left
front. The letter M denotes the speaker assigned as the married speaker.
Invert: Will invert the phase of the speaker.
Mute: Will mute desired channel(s) for tuning individual channels.

CROSSOVER ADJUST
MOBILE APP
If installing a subwoofer, the front and rear outputs will default to a 100Hz high pass
filter to keep the low frequency signals out. If a subwoofer is not being installed, change
the front and rear crossover points down to 20Hz for a full range signal, or to the lowest
frequency the speakers will play down to.
Selecting High Pass and Low Pass will provide one crossover frequency adjustment. Band
Pass should only be chosen if installing just front speakers, with one dedicated amp for
the woofers/mids, a second dedicated amp for the tweeters, along with a subwoofer.
Select the desired crossover slope, 24db, 36db, or 48 db. Higher is steeper, but it is
recommended that one uses High Pass/24db octave slopes for crossovers on a bike.

EQUALIZER ADJUST
Graphic EQ
The front, rear, and sub channels can be adjusted independently within this
tab, with 31 bands of equalization available. It is best to tune this by using
an RTA (Real Time Analyzer).
• The Gain slider on the far left is for the channel selected.

DELAY ADJUST
Allows a delay of each channel. If a delay is desired, first measure the
distance (in inches) from each speaker to the listening position, then enter
those values to the corresponding speaker. Add (in inches) to the desired
speaker to delay it.

INPUTS/LEVELS
Clipping Level - Use this feature to protect sensitive speakers, like tweeters, from being
driven past their capabilities. If the input signal of the DSP clips, the audio will be reduced
by 20dB. Turning down the stereo will allow the audio to come back on at a normal level.
The sensitivity of this feature can be adjusted to the listening preference of the user.
Chime Volume - Not applicable at this time.
Amp Turn On
SignalSense - Will turn the amplifier on when an audio signal is detected, and keep
on for (10) seconds past the last signal. This ensures the amplifier doesn’t shut off
between tracks.
Always On - Will keep the amplifiers on as long as the bike is cycled on.
Turn-on Delay - Can be used to delay amp turn-on to avoid turn-on pops.
Subwoofer Input - For selecting either a dedicated subwoofer input or summed from the
front and rear inputs.
