High Quality USB to Serial Adapter TunerStudio DIYAutoTune

USB to Serial Adapter – TunerStudio. This USB to Serial Adapter has been tested and works properly with all versions of TunerStudio. We highly recommend this adapter is used if your tuning PC/laptop doesn't have a DB9 Serial connector. Or you can use another adapter with a genuine FTDI chipset (which this uses). This adapter includes a 2 foot extension cable, but we only recommend using the extension cable if you have vibration issues with the adapter plugged directly into your laptop. USB cable runs
