INSTALLATION
NOTE
You must have the following minimum PC specifications to install and run ProTune II:
  • Microsoft® Windows® 2000® , Windows XP®, or Windows Vista™ operating system. Windows 95®, Windows 98®, NT®, Windows Me®, or earlier are not supported.
  • Pentium® II 450 MHz processor or faster/equivalent. A Pentium® III-1Ghz or faster/equivalent is recommended.
  • 64 MB of system RAM. 128 MB or more is recommended.
  • 200 MB of free hard-drive space.
  • A desktop resolution of at least 1024 x 768 with thousands of colors (16-bit color) is required. Higher desktop and color resolutions are recommended for optimum use. A modern graphics system with 3D acceleration and 16 MB or greater on-board RAM is recommended.
  • A CD-ROM or DVD-ROM drive is required for installation.
  • A 9-Pin serial COM port or USB to serial converter is required for communication with the replacement ECM.
  • A keyboard and mouse are required for this software.
If you are new to the ProTune II program, you should load it on a computer, familiarize yourself with the screen and the controls. Learn how to transfer files to and from the ECM, and how Calibration Files, Maps and Tables relate to each other. Learn what can and cannot be changed by the program, and how to make and save changes. All of this is explained in the instructions. Have the ProTune II program running on your computer as you go through the instructions. It is easier to learn the program if you interact with it. For learning purposes, there is a sample calibration file included.
ATTENTION: Included on this installation CD is a link to our complete ProTune II Manual. Print it out and keep it with you as you work with the software.
About Dynamometers and ProTune II: The best way to verify optimum performance from your system is to do the final tuning on a dynamometer. Also, the dynomometer must have both an air/ fuel analyzer and be able to apply a load in a steady state to simulate road conditions.
WARNING
Disconnect negative (-) battery cable first. If positive (+) cable should contact ground with negative (-) cable connected, the resulting sparks can cause a battery explosion, which could result in death or serious injury. (00049a)
NOTE
Included on this installation CD is a link to the complete ProTune II Manual. Print it out and keep it with you as you work with the software.
  1. Disconnect the negative battery cable.
  2. Refer to the service manual to remove the OEM ECM. Save the hardware for reuse.
  3. The new ECM mounting uses a rubber plug to protect the module's tuning access connector from the elements. This cover is already installed on the module. Be sure the cover is in place when module is put into service.
  4. Double check the negative battery cable to be sure it is disconnected. Installing the module with the system powered up could cause the motorcycle to run poorly or not at all.
  5. Insert the hook on the left side of the 35-position connector into hinge on ECM. Push the connector onto the contacts of the ECM until the connector fully engages the latch on the ECM.
  6. Install the ECM in the same location as the stock ECM, using the original mounting hardware.
  7. Connect the negative battery cable.
  8. Before starting the motorcycle, with the run/stop switch in the "run" position, turn the ignition switch on for at least 2 seconds, then off for at least 10 seconds more. This allows the idle speed control actuator to reset prior to starting for the first time.
  9. Position the main connector of the ECM in its stock location for maximum protection against the elements.

Connecting the ECM to ProTune II
NOTICE
Use supplied cable to connect ECM to computer. Failure to use supplied cable to connect to computer can result in computer damage. (00605b)
NOTE
You can use an additional cable to supplement length, but the supplied cable MUST be connected to the module.
  1. See Figure 9. After the ECM has been installed on the motorcycle, connect the supplied Communications Cable from the 9-socket connector on the case of the ECM to the 9-pin connector on your computer.
  2. See Figure 10. Launch Pro Tune II. When there is no ECM 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 ECM on COM1:, Checking COM1.
  3. See Figure 11. When the ECM is powered and connected to the PC, the communications status box should illuminate green to show that an ECM is connected and communicating with the PC software.

Figure 10. No ECM Connection
Figure 11. ECM connected
NOTE
The box to the left shows the serial number of the ECM (00031505 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. We recommend the Belkin® F5U409 USB-Serial adapter as the Pro Tune II Software has been extensively tested with this unit.
If you cannot establish a connection with your ECM: Consult the complete ProTune II manual. A shortcut to the manual was installed on your desktop during the ProTune II installation. It can also be found on the installation CD.
NOTICE
Only program ECM with Harley-Davidson supplied calibration files designed for this model motorcycle. Programming ECM with other files can damage the ECM. (00606b)
NOTE
Sending Calibration Data to an ECM: The ECM is pre-loaded with a calibration designated by its label. If the need arises to load a different calibration, Refer to the ProTune II manual for more information.
Basic Troubleshooting
  1. Problem: ProTune II is not communicating with the ECM module. Possible solution:
    1. See Figure 12. Verify the ECM is connected to the computer and the ECM is powered.
    2. Go to the Options drop-down menu and select Serial Port Settings or press Ctrl+J.
    3. Select Auto-Detect to detect the available serial ports on your computer.
    4. See Figure 13. ProTune II will scan all com ports for the ECM.
    5. If ProTune II detected the ECM on a com port, it will automatically connect to the ECM. Select OK to continue.

ProTune II Diagnostics
  1. The recommended method for checking the ECM for diagnostic trouble codes (DTCs) is by using the ProTune II software. DTCs can be read and cleared by clicking on the DTCs button on the upper left of the ProTune II screen with the module connected and the motorcycle powered up. Refer to the ProTune II manual or help files for more information on DTCs.
Check Engine Lamp Diagnostics
NOTE
If you have set your motorcycle to use the check engine lamp as a shift-light, this function will be disabled.
1. The ECM has a feature which can report engine faults by flashing a code via the Check Engine lamp on the motorcycle. Use the following procedures to activate and read the check engine lamp.
a. Turn the ignition switch to the ON position for three seconds (one second pause after the fuel pump stops), and then switch back to the OFF position for three seconds. Repeat this procedure one more time and then turn the ignition to the ON position and wait for eight seconds for the check engine lamp to start flashing.
b. The transmission of a code is always preceded by a series of rapid flashes (about 3 per second). This "intermission" is followed by a 2 second pause in which the lamp is off. The lamp will then flash one or more times to indicate the first digit of the trouble code. The length of time the lamp is illuminated and the length of time in which it is off are each about 1 second in duration. The number of times the lamp flashes indicated the first digit of the trouble code.
c. Following the transmission of the first digit, there is another 2 second pause in which the lamp is off. The lamp will then flash one or more times to indicate the second digit of the trouble code. The number of times the lamp flashes indicates the second digit of the trouble code.
d. Following the transmission of the second digit, there is a third 2 second pause in which the lamp is off. After the pause comes an "intermission", followed by transmission of the next recorded trouble code. All subsequent codes are sent in the same manner, each separated from the next by an "intermission". Once all the trouble codes have been sent the data string is repeated. See Table 1 in the manual for a list of the trouble codes supported.
e. Turn the ignition key switch to OFF. Wait 10 seconds for the ECM relay to click. The vehicle can now be started normally.
