USB to Serial Adapter – Works with TunerStudio!

Description

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′ 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 are more susceptible to noise than RS232, so we recommend using our standard 6′ tuning cable in combination with this adapter.

    Connects right up and communicates great with the engine off. Immediately loses communication once the engine starts. See http://tunerstudio.com/index.php/faqs/76-usb-connectivity

    super fast shipping, installed painlessly (win7 literally was plug n play) also it does NOT need the DB9 straight though serial cable to use it (I had a USB to Serial adapter that did require it)... so nice bonus.

    Worked perfectly first time - driver install was painless, and connection to the MSPNP has been 100% solid.

    This worked flawlessly and connects directly to the megasquirt. I highly recommend this adapter. no need to mess with internal usb adapters. Still allows for use of megaview if you choose.

Drivers for this adapter can be found on the FTDI website.

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.

When should I use the USB extension cable included with this unit?

  • The cable is useful if you are dealing with a high vibration environment. However, it also picks up large amounts of electrical noise. If you are using the USB extension cable and experience problems where the ECU goes offline once you start the engine, remove the extension cable and plug the adapter directly into the USB extension port, and use the DB9 straight through cable to connect the adapter to the ECU.

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?
