The BDM proprietary EFI (ECU) S&S module is a DB9 Serial connection cable that then needs a DB9 (RS232 com to USB, your PC port) adapter and then run the S&S Protune2 software. This software allows very limited access to the module.
The BDM factory stock EFI modules are locked and require a proprietary BOX file and password? by BDM and are not fully accessable to change rev limiter, EFI mapping and other areas. S&S offers the exact same EFI module only unlocked that can replace the factory stock module.
The later BDM EHC modules that have the USB end on the cable can connect to your PC USB port but requires BDM dealer or authorized BDM service center software to gain access to the data.
Connecting the ECU
WARNING! Use the supplied cable to connect the
ECU to your PC. Use of any other cable may result
in damage to the PC or ECU.
NOTE: You may use a 9-Pin serial extension cable
in conjunction with the supplied cable, but the
supplied S&S cable MUST be connected to the
module.
To connect your ECU to your PC:
1. Install the ECU using the separate installation
instructions provided.
2. Connect the supplied Communications Cable from
the 9-Pin socket on the case of the ECU to the 9-
Pin connector on your computer.
3. Launch ProTune II. When there is no ECU
communicating with the PC, the communications
status box at the bottom-right corner of the screen
will flash between blue and black and alternate
between the messages No ECU on COM1: and
Checking COM1:
4. Switch the motorcycle ignition key to the ignition
ON position. Switch the engine kill switch to the
RUN position. This will power the ECU.
Optionally, you may start and run the engine.
5. The communications status box should illuminate
green to show that an ECU is connected and
communicating with the PC software.
The communications status box shows the ECU model
number and hardware revision (55-5002, revision B in
the example above) and the ECU software version
(B831 in the example above). The box to the left also
shows the serial number of the ECU (00029327 in the
example above). This information may be required for
customer support.

If you do not have a serial port on your computer, you
may use a USB-Serial adapter instead. They are
available from computer component vendors. We
recommend the Belkin F5U109 USB-Serial adapter as
the software has been extensively tested with this unit.
If you cannot establish a connection with your ECU:
1. Check that the ECU is powered. The ECU must be
supplied with vehicle power in order to operate.
Your motorcycle ignition key and kill switch
should be set to the ON and RUN positions. Make
sure that the battery level is normal. Try cycling the
power to the ECU (switch ignition off for 15
seconds and then switch on).
2. Check that the cable is connected firmly to the
ECU and the PC.
3. Some PCs may have more than one serial port. If
this is the case, try connecting to the other port(s).
4. The external serial port on your PC might not be
installed as COM1. This is the case on some
notebook computers that use COM1 for other
devices (modems, IR ports, etc). If so, you will
need to change the serial port that ProTune II
checks for ECUs on. Try searching COM2, COM3
etc. instead of COM1. See Serial Port Settings…,
p19 for details on how to do this and for details on
how to detect the port setup of your computer. For
detailed information on the port setup of your PC,
(for Windows XP, 2000 etc.) go to the Windows
Start menu, find Control Panel (which may be in
the Settings menu). Open the System control
panel. Click on the Hardware tab. Click Device
Manager. Under the group labeled Ports the
available serial ports should be listed. The serial
port names will start with the letters ‘COM’. If you
are using a USB to serial adapter,
note its COM number in Device
Manager.
