OBD2 OBD II Diagnostic USB Cable KKL409.1 VAG-COM 409 Review

Average Reviews:

(More customer reviews)I ordered this to communicate with my late model Triumph motorcycle ECU. This is the same model as is sold on eBay from various Chinese retailers but I chose Amazon because of the improved return policy over eBay sellers. The item is fulfilled by Amazon which means I received it promptly and in secure packaging.
While the picture shows a translucent blue device, the one I received is solid black plastic, I can only assume this is due to variations in suppliers or manufacturing.
It worked on my first attempt to connect using the free TuneECU software (when using the recommended FTDI drivers not the ones supplied with the device). What can I say more than that? I haven't tested it with a hundred different vehicles, but I do know for my one application it worked perfectly on my first attempt.
EDIT: To those wishing to purchase this who are dissuaded by the negative reviews, please note: This does NOT come with any software. In fact, the driver CD it does come with is worthless. Just download the correct drivers from the internet (FTDI Serial-USB OBD drivers[...] which are direct from the manufacturer. You will still need some sort of software to interface with your car. Do a quick Google search and I can guarantee you'll find something.
Seriously, don't rate something down because you can't figure out how to use it.
