USB to Serial Adapter

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′ RS232 serial tuning cable in combination with this adapter.  Plug the USB Adapter directly into your laptop (without the USB extension cable) and use the RS232 cable to reach your ECU.  This will provide maximum reliability of the connection, as the USB wire makes a much more noise susceptible ‘antenna’ than the RS232 cable makes.  I could get deeper into the geekery of ‘why’ but just know… that’s what works best, especially if you’ve got a rowdy ignition system!
