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.
Product SKU: USB-2920
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.

Working well for Traction Control and VSS. Going to try for Crank signal now.I have 2 of these already on the vehicle. One at the rear end pinion for VSS1 running on a 4 magnet wheel and one on the front hub reading the heads of the lug studs (6 lugs). Both are working well. I am going to try one on the front of the crank with a 36-1 wheel. I bought 2, one to keep as a spare, since I now have 3 on the vehicle.

Well made, machines easily.Picture is very accurate. It machines easily and is well made. Should be a good improvement over my 8 window stock trigger.

Hall Effect Crankshaft Position SensorI bought this item, it's not dirt cheap to me. But, I purchased it. Using it with ms2 extra. Had to do few steps, solder few wires to make it work. Instructions online available step by step. It was easy enough and the felling was rewarding that I did it. The sensor works beautifully, it does the job very nicely, so far I have no complains. Would say much sharper than the pickup sensor for sure. (Project: rotary engine Rx7) thanks diyautotune.
