Last night I verified that the cable connects to FreeSSM, I was able to pull CEL codes for both the engine and transmission as well as view all of the transmission sensor outputs. It was enough information that I could trace my DCCD issue back to the ABS unit not receiving a signal from any of the 4 wheel speed sensors. Basically this $8 cable (with appropriate drivers and setting com port per above post) and FreeSSM software gives you the power of a $1000 plus dollar Subaru scan tool that the dealership uses. SWEET! It also is able to clear both engine and transmission codes. I have not tried it with Romraider or ECUflash yet but I may test it out shortly. I do have a Tactrix cable that I normally use for that so its not super high priority, but it would be nice to have a cheaper option.

Now I just need to figure out my Wheel speed sensor issue.....

I live in Grand Rapids and was wondering if you still have your OBD2 cable. I bought one on ebay but it's junk. I really need to get my car fixed and don't really have time to wait to ship another cable. Wondering if I can barrow or maybe buy it from you? Thanks

Hey people I'm having some issues too. I have an 04 wrx and I can't get ecu flash to work. I have a ftdi chip vag com cable, and can get rom raider, ecu explorer and another program to work.

I have a cobb off the shelf stage 2 tune on it now and I'm trying to go open source, I have tried unmarring the access port and trying that way. At this piont i have tried 5 different versions of ecu flash, and several different combinations of different step and nothing, just different error codes.

Any tips will be appreciated

After spending the better part of a day struggling to get my $13 cable to work with romraider and ecuflash, I figured I would share what I did to get mine to work.

Windows 10 64 bit

This cable:
VIMVIP VAG-COM KKL 409.1 OBD2 USB Cable Auto Scanner Scan Tool Audi VW SEAT Volkswagen https://www.amazon.com/dp/B00K6498D0..._mvRNAbGTW3V25

Installed drivers from disc that came with the cable. Inserted disc and ran the driver install exe as administrator. One of my issues with getting this cable to work came from not running every program as administrator.

Download ecuflash 1.28 here: https://evoecu.logic.net/mirror/ecuflash/releases/
Do not download the updated ecu definitions! They will not work with 1.28.

Run the ecuflash installation exe as administrator and go through the steps to finish the install.

Plug the cable into your computer and go to device manager to change the com port settings. (Control panel - hardware and sound - device manager - ports (com & lpt) - usb serial ch430 - port settings - advanced - change com port number to com1)

Plug the obd end into your car.

Plug usb into computer.

Connect green test connector.

Run ecuflash as administrator. (I right clicked ecuflash in file explorer and changed the settings to “always run as administrator”

Click options - port - com1

Select read from ecu.

Choose model

You’ll be prompted to turn the key to the on position so do that.

Hopefully it will work and you’re ready to go.

I fought with different drivers for a while because the disc that came with the cable would never work. This issue was fixed by running the driver install as administrator.

Also trying to use the new ecu definitions with ecuflash 1.28 caused it to crash. Using the definitions that come with 1.28 worked fine for me.

Changing the com port to com1 was another fix for one of my issues.

Now I'm finally able to get my stage 2 setup going on my fxt for $13!

Default It does work, but need to be wary and persistent

Can confirm that using the VAG COM from Amazon does work. I borrowed a friend's VAG COM KKL 409.1 USB cable and basically plugged it into my Windows 10 64-bit Laptop, and Windows installed the drivers automatically. I did not have to install any drivers via download or from a disc.

The chipset in the cable is the CH340 USB to Serial (WinChip China):

After the the cable was plugged in, and the drivers installed you can check the port, on my laptop it automatically assigned the cable to COM3. I left it on that port and kept the default communication parameters, 9600, 8, N, 1.

I installed as administrator, the ECUFlash 1.28 but probably could have used a different version, but I didn't test doing that. I then right clicked on the program after installing and ran it as administrator (just in case). It loaded up and then I went to Options -> Port and selected the radio button for COM3. I noticed there was an error message 'error loading FTD2XX.dll' but ignored it because this cable does not use the FTDI chipset.


I then tried to read the existing flash rom, but before doing that, I needed to apply 12v to the Red with White stripe wire at the 4 pin diagnostic jumper and connect the green test leads together. Soon as I did that I was able to read the ECU and save it without an issue. Turn the key on, then select the correct model and year, then hit the 'READ' button.

Because I am trying to pass BAR inspection for my swap, I needed to update my ECU with the correct flash file, 04 WRX M/T 2.0L (A4TF520F). So, I opened up this file in ECUFlash and then went ahead to write to the ECU. The flash wrote but only partially completed due to insufficient voltage, so without turning off the key, without unplugging the cable, without reloading the ECUFlash, I just went back and hit Write to ECU, I had to do this about 10 times because the battery in the car was bad and I also had to put on a battery charger to try to maintain 11.6 to 12.6 volts. The flash file finally went through without any error.
