Pre-Installation

The BD X-Tuner for the GMC/Chevrolet Duramax (LBZ Engine) is a very simple instrument to operate. All operations take place inside the cab with the downloader hooked up to the OBD II diagnostic port. Operating this downloader does not require a mechanical background. While operating this downloader we encourage you to simply follow the instructions provided on the screen of the X-Tuner; the instructions on the screen are easy to read and comprehensive. The X-Tuner is meant for the 6.6L Duramax LBZ Engine (2006+), and cannot be used for any vehicle other than this specific application. This instruction booklet will provide you with a detailed description on how to perform downloader operations and is split up into easy-to-read sections labeled with headings. Once you have downloaded a power program into your vehicle, remember to always keep the downloader with you, if possible as you may want to change the power program that is loaded, or to check and erase Diagnostic Trouble Codes (DTC's) on the road.

**** IMPORTANT ****

The power program must always be removed before taking the vehicle in for any kind of service, as it may interfere with diagnostic tools used by your dealer. Sometimes, even if your truck does not require a diagnostic service, the dealer may flash your trucks' computer without your knowledge, so it is absolutely recommended to remove your power program BEFORE bringing it to your dealer. In the event that your trucks computer is flashed while your program is loaded, your X-Tuner may have to be sent back to BD to be re-flashed.

IF STACKING PERFORMANCE PRODUCTS, IT IS NOT RECOMMENDED TO HAVE BOTH PRODUCTS ON THE HIGHEST OUTPUT SETTING. FOR EXAMPLE A COMMON STACK IS TO HAVE THE EDGE JUICE SET ON LEVEL 3 AND THE X-TUNER ON TUNE 1 OR TUNE 2.

Installation

Make sure that your vehicle is in the key off/engine off position, with all electronics (such as the radio) turned off before you plug in the X-Tuner.

Locate the fuse box inside the engine compartment, on the driver's side. Remove the fuses marked in the picture above. There are four fuses that have to be removed in total:

TBC BATT / TBC IGN1 / RADIO / INFO

Inside the cab, connect the communications cable that came with the downloader into the top of the X-Tuner and the other end into the OBD II port (see picture on the right). The OBD II port is the diagnostic port located underneath the dash on the driver's side of the vehicle.

OBDII Port

The downloader will power up with a BD logo. Press any key to continue to the next screen. It will then ask you to confirm that you agree with the warranty statement that can be found on page 19 of this instruction booklet.

At this point, the downloader will ask you to turn your key to the ON position (but do not start the engine).

Main Screen

The main screen will give you two options to choose from: DOWNLOAD ­ Select this option to download a power program, remove the vehicle's speed limiter, adjust tire size for the speedometer, or to return the program to stock. DTCs ­ Select this option to view and erase diagnostic trouble codes.

Download Function

Highlight the downloader option from the main menu, and press the Y key.

If this is the first time you've used the tuner, then the downloader will then read and save the vehicle's stock information. This procedure will take 5-7 minutes. If this is not the first time you've used the tuner, then it will read and verify your trucks information, and then proceed to the tuning menu.

Once the save/read is complete, the downloader will display a list of available power settings. Use the up/down arrows to move through and select a power program. Refer to the Power Settings chart on page 3 for more information on available power levels. Using the "Factory" power level returns the truck to stock, or leaves the OEM settings intact if the truck has never been programmed.

Speed Limiter

The X-Tuner gives racing enthusiasts the option to remove the OEM speed limiter/governor. This allows the vehicle to reach speeds in excess of where the OEM governor was set (most trucks are set below 100mph/140kmh). By selecting "Yes" to remove the speed limiter you agree that your vehicle has the appropriate tires, suspension and any other necessary modifications rated for speeds in excess of 130mph.

The speed limiter removal function of the X-Tuner is adjustable. Available options are:

50 - 135mph in 5mph increments.

THIS MODIFICATION IS INTENDED FOR RACE PURPOSES ONLY AND SHOULD NEVER BE USED ON A PUBLIC ROAD OR HIGHWAY.

Adjusting Tire Size

If your truck has aftermarket tires that are larger than the truck's stock size, then your speedometer is most likely reading an erroneous speed value. The X-Tuner has the ability to adjust the tire size and correct the speedometer to read the correct speed.

Measure your tires from the ground to the top of the tire. Enter that number (in inches) using your up/down arrows on the X-Tuner's keypad. Available options are:

25.00 ­ 45.00" with 0.25" increments.

Due to the programming in GMC computers, selecting a tire diameter larger than 35.00" may cause the ABS light to come on.

The X-Tuner will now compile all the parameters you specified and will upload the proper power program into your truck's computer. This process will take roughly 3-5 minutes.

The X-Tuner will now complete the download with a simple test procedure. Follow the instructions provided on the screen.

Once the verification is complete, the X-Tuner will finish the flash and re-initialize the truck's computer. The X-Tuner will count down from 9. DO NOT DISTURB THE TUNER.

You are now done! Congratulations! Have fun, but be careful with your new-found power.

Returning To Stock

This option is for when you are taking your vehicle in for a diagnostic service, or just want your settings to be back to the OEM specifications. Plug in the X-Tuner and select the Download option from the main menu. Once you have entered the power level selection screen, select "Factory" and then press "Y". Follow the instructions set out on the downloader. When you are finished, the X-Tuner will have returned the vehicle to the stock power level.

DTC Function (Diagnostic Trouble Code)

The DTC function will display all diagnostic trouble codes set on your vehicle. This function will also allow you to read and erase trouble codes from your vehicle's ECU.

To erase DTC codes, simply press "Y" and all DTC codes will be erased. If no DTC's are displayed, then simply unplug the X-Tuner and cycle the key.

If an error code is displayed, unplug the X-Tuner, wait ten seconds, then plug it back in. 3. Once the downloader has been plugged back in, it will again display a prompt to enter the recovery mode. Press "Y". 4. The X-Tuner will recover the vehicle's programming by returning it to stock. 5. Once the vehicle finishes restoring the stock program, the power programming process can be safely restarted.

Updating Your X-Tuner

Requirements: Microsoft .NET Framework v1.1 Windows XP WinZIP, WinRAR or equivalent The X-Tuner has the ability to update via a USB connection. The port is located on the top of the X-Tuner module, beside the serial port that the OBDII port cable attaches to. Updates can be downloaded via BD's website. If it is the first time you are updating your module, you will have to register and create a user profile. The X-Tuner update program is a small and easy to use application. This program can be used with Windows XP. It is mandatory to download and install the Microsoft .NET Framework v1.1 or v2.0 package from the Microsoft Downloads website (http://www.microsoft.com/downloads/) or the program will not run.

X-Tuner's USB Port

A USB A-B cable (see photo to the right) will have to be purchased separately in order to use this function. This is a widely used cable in the computer market (used mostly in newer style printers & scanners) and can easily be picked up at any retail store that sells computer parts. An example would be Best Buy, Circuit City or Future Shop.

Running the Update Program

** NOTE ­ When re-flashing your X-Tuner to the latest version, you MUST return the stock program into your truck's computer, otherwise the tuner will not update. This is a security feature to ensure that you don't overwrite the stock program in your tuner. Open your Start Menu, browse to "Duramax Downloader", and execute the application located inside. This will open up the main X-Tuner update program window. You may now plug your XTuner into your computer. The X-Tuner should light up and display the BD Power logo on its screen. Do not push any buttons on the X-Tuner at this time. Press the Upgrade button in the update program on your computer. It will begin the reflash process.

While the update program is progressing on the computer, you should see the display on the X-Tuner running the flash upgrade program at the same time, as shown on the diagram to the right. DO NOT DISTURB THE X-TUNER DURING THIS PROCESS.

Once the flash is complete, the X-Tuner will run a short checksum test of the internal software. After this is complete, it will then automatically close the X-Tuner update program, and will re-load the BD logo screen on your X-Tuner module. You can now unplug the X-Tuner. The update is now complete! Feel free to reload the new program onto your truck's computer.
