It's a very straight forward install. We like to use a pencil eraser to clean the board/connections prior to install. Then from there, take your time and run the analog wires. Make sure your software and drivers are up to date, and start tuning. For anyone with a TT 5.7 chip that now has a wideband/powerlogger, the 6.1 TT chip with this combo allows for point and click BLM tuning with wideband correction. Tuning the car becomes a lot easier, especially on E85 setups ( I am setting up so many cars for E85 this summer.)
