USB To Serial Adapter

Product Details

Used with your MegaSquirt ECU!

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 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.
