    The cable arrived in a timely manner and when used on the 2001 Newbeetle, it worked fine with VCDS. Good product. Thank you.

    So far so good.

    Was able to pull codes from Mk4 2001 VW Jetta TDI with VCDS Lite in Windows 10 no problem. Rather slow shipping to Canada - ordered Dec 7, shipped Dec 11, delivered Dec 27.

    Run Aprilia Guzzidiag on 2017 Tuono Factory

    Posted by Unknown on 27th Nov 2017

    Was having a difficult time sourcing the adapters needed to run the Guzzidiag software to update my 2017 Tuono after installing the race ecu and aftermarket exhaust. This site had both cables I needed listed as a set. Worked perfectly. The quality may not be the greatest (or maybe it is, didn't matter, didn't assess) but I only needed it to work for 2 minutes anyway, which it did flawlessly.

    Highest quality cable i've owned. There is a reason there are so many cheap ones on the market....

    Not the use it was made for, but it works!

    We bought it in order to modify it for use on motorcycles, and just remapped the ECU of one a few days ago, so money well spent!

    it works, kind of....

    Posted by Darrell Burns on 1st Jul 2016

    I have Cascade (a scanner emulator) that only is compatible with a cable with the ftdi chip. Not wanting to spend a lot of money on a quality cable that had this chip (also would have an ELM327 processor) I choose to save some money and try this cable that didn't have the ELM processor. It allows me access to most functions through the OBDII port, but unfortunately not all the functions that I was needing to use. So, I ended up buying the better cable anyways. It's true you get what you pay for, so keep that in mind when thinking of purchasing this cable.
