Duramax Programming Software DDT
TunerTM To install the Duramax Diesel Tuner and PCM Programmer, insert your Wester’s Garage DD Tuner CD into your CD ROM drive and run the setup program in the root folder (ddt_setup). This setup program will install both the DD Tuner and PCM Programmer on your PC. Follow the on-screen directions to complete the installation.
Program RegistrationTo use this program you will need to register it first. Your registration information is located on the label on the back of the CD case.
To register, run each program. When the program starts up, the registration screen will be displayed.
Enter your Supplied Customer ID and Serial Number in the appropriate boxes and click on the ‘Register’ button to complete the registration. If you have entered the information correctly, you will receive a meesage saying that the registration has been successful.
PCM Programmer SetupBefore proceeding be sure you have specified the correct Comm port that you will be using to communicate with the PCM. To set the correct Comm port, select 'Comm Port' from the 'Setup' menu. This will display the following screens: Before proceeding be sure you have specified the correct
Select the Choose an available Comm port you wish to use and click 'OK'. The program will save this selection so you don't have to set the Comm port again unless you want to change to a different port. If you're changing your USB adapter location, you may have to check the available Comm port. Reading The PCMTo read the calibration currently stored in the PCM, select 'Read PCM' from the 'Tools' menu.
The program will then ask for a file name to give to the calibration file that will be created when the PCM is read.
Type in a valid name for your calibration file into the ‘File name:’ box and click on the ‘Save’ button to continue.
You can add calibration notes to your calibration file by typing the notes into the ‘Calibration Notes’ box in the lower half of the screen before clicking on the ‘Save’ button. These notes will be saved with the calibration information, and is stored in the PCM.
After clicking on the ‘Save’ button the read PCM start screen will appear.
Before proceeding, connect the RS-232 to OBDII converter interface to the Comm port on your PC. If your PC has more than one Comm port, make sure you connect the converter to the com port that you specified on the Comm Port Setup screen. Connect the other end of the converter to the ALDL diagnostics connector on the vehicle. At this point, the light should be flashing on the converter. If not--check for a blown fuse for the courtesy or cigarette lighter circuit. Before proceeding:
Once the cable is connected, turn the ignition key on but DO NOT start the engine. After turning on the ignition, wait about 10 to 15 seconds to clear the GM security delay before proceeding with reading.
Now click on 'OK' to begin the PCM read process. If all the connections have been properly made, the program will begin communicating with the PCM, sending the necessary instructions to start the memory read process The following status window will be displayed during the read process:
The progress meter shows the progress on the reading of the PCM as it proceeds and the Status window describes what part of the process in currently underway. Depending on the type of vehicle and the PC you are using, the read will usually take about four minutes. d process is complete, the message shown below will be displayed:
Click 'OK' to complete the PCM read and close the "Read Complete" message box. If you got any warning messages after reading the PCM call us immediately or email us with the warning information. The calibration information from your PCM will now be stored on your PC. Opening A Calibration File
To open a PCM Calibration file
select 'Open File' from the File menu or click on the
Open File
This will display the 'Open File' dialog box. Select the desired file and click the 'OK' button.
Select a calibration file and click on the ‘Open’ button to load the calibration file into the Duramax Diesel Tuner program. When you click on a calibration file name in the Open File screen, any notes that have been saved with the calibration file will be displayed in the Calibration Notes box at the bottom of the screen.
Editing A Calibration FileOnce you have loaded a calibration file into the Duramax Diesel Tuner program your are ready to begin tuning by editing the various calibration parameters. Calibration ParametersThe Duramax Diesel Tuner program uses four different formats of calibration parameters to display the various calibration values. Switch Type Calibration ParametersThe switch type calibration parameters are values that have only two states such as on or off , or Enabled or Disabled . This type of parameter will include calibration items such as ‘EGR System Enable’. You can totally disable trouble code self tests in this section also.
Constant Type Calibration ParameterConstant parameters represent single values or calibration constants such as the fan on temperature.
2D and 3D Calibration TablesCalibration Tables are used to display a series of values that depend on one (2D tables) or 2 other parameters (3D tables). An example of a typical 2D table would be the Knock Attack Rate Vs. RPM (Gasoline calibration).
A good example of a common 3D table would be the Spark Advance versus Load versus RPM table (Gasoline).

Diagnostic Type Calibration ParametersThe diagnostic type calibration parameters are paremeters that control the operation of the OBDII diagnostics.
You can disable the diagnostic test, as well as how the test is actually reported. Accessing Calibration ParametersThe calibration parameters are grouped by the parameter type as described above. To view and edit the various calibration parameters, select the type of parameter you want to work with by clicking on one of the calibration parameter menus at the top of the Duramax Diesel Tuner program screen.
For example, to view table parameters, click on the ‘Tables’ menu. The table parameters are then arranged in sub-groups according to function. When you click on one of the calibration parameter menus the sub groups are then displayed.
To select the sub group you are interested in click on the sub group name to display all the parameters in that sub group. To make the calibration parameters easy to understand and more convenient to edit, the Duramax Diesel Tuner program displays all table values in correct engineering units rather than the binary values actually stored in the calibration file.
You may view as many tables at once as you want. To view another table, simply select it from the menus. To close a table, click on the window close box (X) in the upper right hand corner of the table. You can even open two programs, loading separate calibrations if preferred. However--there's a built in compare feature so you can compare two different calibrations.
Note: You will NOT lose any changes that have been made to a table by closing it. The displayed table can be sized in height or width by clicking on an edge and dragging where you want it. You can also move the tables inside the window for easier viewing. Saving a Calibration FileOnce you are finished editing the calibration file you need to save it. To save the edited calibration file to a different file so you don’t over-write the original calibration file,select 'Save As' from the 'Files' menu.
This will display the 'Save As' dialog box. Select another file or type in a new file name and click the 'Save' button.
Programming the PCMTo install a new calibration you need to program the new calibration into your vehicle’s PCM. This is done using the PCM Progrmmer. Run the PCM Programmer, click on the ‘Tools’ menu and select ‘Program PCM’ from the drop-down list.
An Open File dialog screen will then be displayed.
Click on the file you modified or read to use to program the PCM and then click on the ‘Open’ button. This will display the Program PCM connect message. Do not attempt to program your PCM with any files other than what came from your vehicle computer.
The following are recommendations for the successful programming of your PCM: · Before programming the PCM, make sure you can successfully read the PCM. This is a very similar process and if that is successful, then the programming should also work fine. YOU CAN NOT DAMAGE YOUR PCM BY READING IT. Remember to pull the fuses (Disable On-Star) as required...they're all under the hood. · Make sure the car battery is in good condition and fully charged. DO NOT try to program the PCM with a battery charger connected to the car battery. The correct range of the battery voltage for PCM programming is relatively narrow. · If you're using a laptop, make sure the laptop battery is fully charged. Plug it in--it's not worth the risk. Do NOT power up your laptop with the vehicle battery via the cigarette lighter adapter. If this fuse blows--communication with the PCM is lost. · Make sure you have good connections between the PC, ALDL connector and the interface cable and that they are not likely to be unintentionally disconnected during the programming process. · Disable all power management functions on your PC--set your PC or LAPTOP up for "ALWAYS ON". (If you don't know how to do this, call us). · Disable all screen savers on the PC--set them at maximum or disable them alltogether. · Make sure there are no other applications (programs) running on your PC, including virus checkers -- use the antivirus from www.free-av.com Other anti-virus programs seem obtrusive.
