Ok, that worked, I was able to run Learning View, ROM Raider Logger, and read the OEM basemap with the current version of ECUflash using the Tactrix drivers and the VAG-COM cable. Now I guess I better get busy and actually install the new parts.
Thanks to GateTwelve for the tip on using the Tactrix drivers and the current version of ECUFlash. And thanks to qikslvr for starting and maintaing this thread!
Woowhoo, this has saved me a boatload of money now that I don't have to buy the Tactrix cable.
