Description

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!

Am I required to use this particular adapter for connecting to MegaSquirt?

  • It is not the only adapter that can work, but our tech department is very familiar with this adapter and it is the only adapter we can provide full technical and warranty support for. With this adapter, you can talk to a support team who both knows the USB adapter and knows MegaSquirt fully.

Why would I get less noise with the DB9 extension than with the USB extension?

  • The RS232 side of the system uses a +12 to -12 volt swing to send a signal. USB communications use a 0.0 to 0.3 volt signal. With a larger amount of signal and the same amount of noise, RS232 has a much better signal to noise ratio than USB in the same environment.

What chipset does this adapter use?

  • It uses an FTDI USB to RS232 converter chipset.

Where can I download the latest driver version for this adapter?

    TunerStudio does not support IOS. For a display app, you could use RealDash, which would connect over WiFi with a suitable WiFi to RS232 adapter.
    3. I have an Insignia - 1.3' USB-to-RS-232 (DB9) PDA/Serial Adapter Cable laying around at my house, would i be able to use this in place of the adapter you guys sell?

    It should work if it has a FTDI chipset, and will probably work if it has a Prolific chipset. Some other chipsets like the CH340 are more problematic. We would not be able to provide technical support for diagnosing problems that appear to be caused by the Insignia adapter if any arise; you would need to contact Insignia's technical support if you run into driver issues or similar problems.

    Download and run this setup program from FTDI. That should get it working; if it does not, please email us and we'll get this figured out.

    Please try downloading and running the latest Windows driver, and see if that fixes it. We are using these on Windows 10 computers at our shop without any trouble.
