This article will guide you how to correctly install VAG-COM 409.1 KKL USB cable on Windows and VCDS software.

CAUTION Using VAG-COM 409.1 KKL:

In our experience, we don't recommend depending on VAG-COM 409.1. Because it's functionality is extremely limited. In addition — you'll need to pay extra $97 to upgrade free VCDS-Lite software to full version. And even if you do upgrade — it can only scan vehicles made up to year 2004.

For that reason we recommend to get the complete VAG-COM 2020 cable with original, unlocked and full version of VCDS software from Ross-Tech™ — by clicking here.

STEP 1: Download and Install VAG-COM KKL 409.1 Drivers

Uninstalling drivers. Uninstalling drivers is the most difficult part of the process, and it’s still not that hard. It’s a necessary step to take in order to install Bluetooth Driver Installer. You’ll need to navigate to your Device Manager through the Windows start menu. Then, you’ll right-click on the device you want and click.

(DO NOT connect cable to your computer yet. Only do this when you're instructed below.)

Start by downloading the VAG-COM Driver Pack 1.

Here's how to install on different Windows versions...

  1. The driver download area could be called by any of several different names including Downloads, Software Downloads, Driver Downloads, Drivers, Drivers and Firmware, Drivers and Software, etc. If you visit a website's home page first, look for a Support area. Any driver download options will probably be located within that area.
  2. The Device Install Kit download site does not provide access to all Emerson Process Management device files. Device files distributed on DeltaV and AMS Device Manager release media are not duplicated for download from this site.

Windows Vista, 7, 8, 8.1, 10:

Uncompress the file. Double-click on 'Install.exe' to install the drivers. When complete — plug in cable into any USB port on your computer and wait for automatic installation to complete.

If install is successful, move onto Step 2.

If installation fails, see below: Troubleshooting: If Drivers Failed To Install

Windows XP:

  1. Uncompress the file. Double-click on 'Install.exe' to install the drivers.
  2. Plug cable into any computer's USB port.
  3. 'Found New Hardware Wizard' will start and it will ask you 'Can Windows connect to Windows Update to search for the software?'. Select 'Yes'.
  4. Select 'Install the software automatically'.
  5. After the installation is complete, click 'Finish'.
  6. 'Found New Hardware Wizard' will start once again because there are two drivers for this cable.
  7. Go through the same steps as explained above to install this second driver.

If install is successful, move onto Step 2.

If installation fails, see below: Troubleshooting: If Drivers Failed To Install

Troubleshooting: If Drivers Failed To Install:

Installation failed? Download here VAG-COM Driver Pack 2.

Unextract the file into any folder. Then while your cable is connected to the computer — go Device Manager.

  • Windows Vista/7/8/10: Control Panel » System » Device Manager
  • Windows XP: Control Panel » System » 'Hardware' tab » Device Manager

You'll see a device similar to 'USB Serial Port' under either 'Other devices' or 'Ports (COM & LPT)'.

Right-click and choose 'Update Driver Software'. Like this:

Then select the location where you unextracted Driver Pack 2. Let it install.

STEP 2: Discover Port Number that VAG-COM KKL Cable is Using

Go to Control Panel.

  • Windows Vista/7/8/10: Control Panel » System » Device Manager
  • Windows XP: Control Panel » System » 'Hardware' tab » Device Manager

Expand 'Other devices' or 'Ports (COM & LPT)'. Whichever contains 'USB Serial Port'.

Next to 'USB Serial Port' — you'll see a number.

If the COM port number is between 1-4, then everything is fine. Move onto Step 3.

If the COM port number is above 4, then we'll have to change it so it's between 1-4. Here's how...

Right-click on 'USB Serial Port' and click on 'Properties' — as per below pic:

Then:

  1. Click: Port Settings
  2. Click: Advanced
  3. For 'COM Port Number' — you MUST choose any number between 1-4.

That's it! Now let's test if everything is working. Move onto next step below...

Cable should be plugged into computer.

  1. Start VCDS-Lite software.
  2. Click 'Options' button.
  3. You will see 'Select COM Port' box. Select the 'COM Port' number as explained in Step 2.
  4. Click the ‘Test’ button.
  5. If everything is good, it should display 'Interface Status: Found!'.
  6. You can now connect other end of cable to car. Turn on ignition. And you're ready to start diagnosing!

If test is not successful — check the following:

  1. Other software or devices using USB ports or that same COM Port could be conflicting. You should uninstall the suspected software or device for troubleshooting this problem.
  2. It should be noted that VAG-COM 409.1 KKL cable does not work on vehicles running on CAN-BUS System.
  3. Cable must be plugged into the vehicle with ignition ON.
  4. Test the cable with each COM Port from 1 to 4 in Windows Device Manager.
  5. Make sure that the driver is installed and configured as explained in Step 1.
More Troubleshooting Tips:
  • Only Audi, Volkswagen, Skoda and Seat vehicles are supported. Other brands will only work for generic OBD-II functions.
  • If VAG-COM 409.1 KKL cable doesn't connect — or if you get the error message 'Can't Synch Baud Rate' — then go to Options and set Start Baud to 9600. If 9600 doesn't work, try 4800 and 1200. Turn the vehicle's ignition OFF and back ON after each failed attempt to connect.
  • If you have installed VCDS software before or from another source, uninstall all versions of VCDS software right now, and delete directory 'C:Ross-Tech'. Then install latest version of VCDS-Lite software by clicking here.

Q What is RomRaider?

RomRaider is open source software (licensed under the GPL), developed by enthusiasts, which allows for tuning and data logging of Subaru ECUs without having to invest in expensive hardware and software. Best of all, RomRaider is free.

Q How does RomRaider allow me to tune?

You must first retrieve a copy of your ECU’s image from your vehicle by using an additional program called EcuFlash (discussed below). A special cable, manufactured by Tactrix, is used to connect your laptop to the OBD-II port in your car (which is located below your steering wheel). Once a copy of your image (also known as a ROM) is downloaded from the vehicle’s ECU to your computer, you can then use RomRaider to make tuning changes to this ROM. Once you’ve finished with your changes, you can then save a copy and transfer this edited image back to your vehicle’s ECU in a process known as flashing. As long as you keep a back-up copy of your original image, you can revert back to it at any time. In addition to tuning, RomRaider also allows you to data log your Subaru to monitor the results and safety of your tune.

Q Does RomRaider only work with Subarus?

Download Tactrix Port Devices Driver

Currently, RomRaider primary support is Subaru but it’s possible to support others.

Q Which Subaru models are supported by RomRaider?

A list of current supported Subaru ROM revisions can be found here: SUPPORTED ECUS. RomRaider supports hundreds of different Subaru ROM revisions from all over the world.

Q When will I be able to tune my Audi/Mazda/Mitsubishi/Other car with RomRaider?

There is currently limited support for other ECUs. To add RomRaider support for your ECU, the following would need to be done:

  • A method to read/write your ECU image from your car needs to be available or developed.
  • Once an ECU image is available in unencrypted form, the image needs to be reverse engineered and a RomRaider map definition created.

Try checking your specific car’s community forums first to see if anyone has made any progress on the above requirements.

Q What is everything I’ll need to start tuning my car?

You will need:

Note: Some of the links below require you to be a registered member of the site’s forums in order to view the download
  • The RomRaider software - always use the latest version available HERE.
  • The latest RomRaiderECU definitions file (this file describes the location and format of data for different ROM revisions) - available HERE. The RomRaider software does not ship with ECU definitions and these are required for the software to be functional.
  • The latest RomRaiderLogger definitions file (similar to the ECU definitions except that these work with RomRaider’s logger to define ROM specific logging parameters) - available HERE. The RomRaider software does not ship with logger definitions and these are required for the logger to be functional.
  • RomRaider is written in Java, so you need to make sure your computer supports Java and that it is updated with the latest 32bit (x86) version software, even if your system is 64bit (x64).
  • EcuFlash software (to read and flash ROMs) - download the latest version, found HERE as well as the latest EcuFlashECU definitions found HERE.
  • A Tactrix OpenPort cable for Subarus (connects between your laptop and OBD-II port) - purchase HERE.
  • A jumper block may be required for your Subaru to enable flashing. There are two versions, one for the 01/02 WRX and another for the 03–05 WRX. These can be purchased from Tactrix or they may be bundled as a package with the OpenPort cable for an additional $20. You can also buy these adapters in a complete set at your local Subaru dealer (~$30 part number 24036AA010). You can also use a jumper wire on the flash block as well. Drive-by-wire Subarus (32-bit ECU) do NOT need the jumper block at all.
  • A modern laptop with a USB port.
  • Proper gauges are recommended when tuning. These include, but are not limited to, a boost gauge and a wideband oxygen sensor.
  • Knowledge, patience, and practice. These take time to acquire. RomRaider’s forum is a great resource, but also consider getting some books and reading NSFW’s Incomplete Guide.

Q Which version of the Tactrix OpenPort cable do I need?

Port

The OpenPort 2.0 is the latest version of the Tactrix cable. This new version of the cable supersedes all prior versions and is the only version currently being sold by Tactrix. Older versions of the cable, such as the OpenPort 1.3, may be used for reading/flashing select non-CANbus Subaru ECUs. The OpenPort 2.0 supports reading/flashing of all Subarus supported by the older cables and adds the ability to read/flash the newer CANbus ECUs (08+ Impreza and 07+ Legacy/Outback/Forester/Tribeca) as well as other new features. All versions of the OpenPort cable have the capability to log ANY modern Subaru. RomRaider logging with the OpenPort 2.0 requires RomRaider version 0.5.1b or later.

The following table outlines the known OpenPort cable compatibility for reading/flashing with EcuFlash. Note: this table only indicates the ability to read/flash, not necessarily the ability to tune. Tuning support is dependent on whether or not a user has submitted a specific ROM revision and it has been added to the RomRaider/Ecuflash definitions (check HERE).

Q How is the OpenPort 2.0 different from prior versions of the cable?

The OP 2.0 supports all vehicles supported by the old versions plus offers a number of new features:

Tactrix Cdm Driver

  • The ability to read/flash Subaru CANbus ECUs (generally 08+ Impreza 2.5i/WRX/STi and 07+ Legacy/Outback 2.5i/GT, Forester 2.5/XT, Tribeca)
  • The ability to read/flash Evo X (future feature with EcuFlash update)
  • J2534 PassThru support as well as additional protocol support which could allow for independent developers to create software to read/flash/log vehicles other than Subarus and Mitsubishis.
  • J2534 support will also allow users to potentially use other J2534 compliant software with the OP 2.0 such as OBD-II diagnostic software.
  • Ability to log supported Innovate devices from the Innovate Motorsports 2.5mm stereo data bus.
  • Standalone data logging to microSD card allows you to log without a laptop.
  • Field upgradeable firmware allows users to update OP 2.0 firmware for new features.
  • Detachable, widely available USB cable allows for cheap and easy replacement if damaged.
  • RGB status LEDs
  • J2534 is currently only supported on Windows platforms as there are no drivers for other platforms.

Tactrix Software

Q Does RomRaider’s logger support the OpenPort 2.0?

Download Tactrix Port Devices Driver Updater

Yes, versions 0.5.1b and later of RomRaider support the OP 2.0. You will need to install Ecuflash version 1.40 or later to install the proper drivers and update the firmware for the OP 2.0.

Q How safe is reading, editing and flashing my ECU?

Remember, that RomRaider and the definitions file are always changing. This means that the software is being tested to fix any bugs and problems that may arise. As such, it is recommended for advanced users. There have been quite a few successful flashes and tunes, but that doesn’t mean there won’t be a bug, error or misrepresentation of data that might cause serious problems down the road for a user. Remember, this software is not a commercial product, with money set aside for R&D. It was created by a group of enthusiasts who work in their spare time, for free, on the project.

Even if you experience no bugs or errors, there are no safe guards in place to prevent you from making improper tuning changes resulting in a blown motor and/or unexpected behavior when driving.

Q What is the worse case scenario if something goes wrong?

The problems that have the potential to occur include, but are not limited to:

Tactrix Openport 2.0 Driver

  • An unreadable/unusable (bricked) ECU.
  • A blown motor and its subsequent damage.
  • Unexpected behavior on the road or track that may cause injury or death to the user as well as others.
  • Violation of local and/or federal laws due to the modification of the factory ECU.

DISCLAIMER: By using RomRaider and its ECU definitions file, either directly or indirectly, you agree to assume 100% of all risk and RomRaider’s creators and contributors shall not be held responsible for any damages or injuries you may receive or cause.

Q How can I limit the risk of something going wrong?

Tactrix Ecuflash

  • Make sure your computer is running well, does not have a tendency to lock up or shut down, and is virus and spyware free. When flashing, make sure the laptop is plugged in and not just running on the battery. Turn off any power saving functions, especially those that shut down the hard drive, enter standby/hibernation or “speed step” the processor speed to a lower level (if possible). Close out all other programs except for EcuFlash before starting. Make sure any firewall software does not interfere with EcuFlash.
  • Always use EcuFlash’s “test write to ECU” before trying the actual flash especially when something has changed in your setup from a prior successful flash (new drivers, new software, new computer, etc.).
  • Make sure your car’s battery, charging and electrical system is working properly.
  • Make sure the OpenPort cable is securely connected and not in a position that can be yanked out easily.
  • Always check for and use the latest version of RomRaider and EcuFlash, as well as the latest ECU definitions for both.
  • Do not edit a table if you are not 100% sure what it does (read the Table Properties).
  • Always keep a back-up copy of your original ROM in a safe place.
  • When tuning, small changes each flash is better. Use RomRaider’s logger to study the effects of the changes on your car. In addition, it is recommended that you have, at a minimum, a boost gauge and a wideband oxygen sensor.
  • Do not flash your ROM if RomRaider gives you an error message that the “real value and byte value conversion expressions are invalid” or any “out of bounds” error. This means there is an error/corruption in the ECU definitions file. If this is the case, it can save the wrong values in that particular table, which may occur whether you specifically edited the table in question or not.
  • After editing, save the ROM, close out RomRaider and then reopen RomRaider and your saved ROM. Make sure the changes were actually made. Also, triple check the values you edited to make sure they are exactly what you intended them to be.
  • Do not rely solely on the table help text in RomRaider to tune your car as they are simply an overview of the function of the table and not a detailed explanation. Make sure that you understand the impact of changing the data in a particular table and how all your changes will interact with one another. Use the RomRaider forums to search for answers or ask questions about ECU logic.
  • Tuning is not for beginners set out to experiment. Even seemingly small changes by a novice can result in a blown engine.
