This FTDI chipset USB to Serial Adapter has been tested and works properly with all of our ECU products and all versions of TunerStudio on a wide range of operating systems. This is probably the most common item we see people come back for after a purchase, so we highly recommend grabbing one now! We highly recommend this adapter is used if your tuning PC/laptop doesn’t have a DB9 Serial connector. You can use another adapter with a genuine FTDI chipset (which this uses) and you’ll probably be good, but if you grab this, you know you’ll be fine.
We recommend using a standard 6′ serial tuning cable in combination with this adapter.
