    Great buy

    The software was installed on my laptop by Katey via remote link. Using the diesellink it connected to my truck with no problems at all. The diesellink is a very well made product, comes with all the cables needed. Customer service at Diesel Laptops is top notch, they can remote into your pc if you have a web connection to look at potential problems. Based on how they have helped me I will definitely be more business with them!


    From Diesel Laptops I purchased a Drewlinq univ adapter. works as advertised with OEM
    software. My OEM stuff is Cummins, Volvo/Mack and DDDL works great with them.

    More then just heavy duty trucks

    I bought this adapter for the sole reason of it being a good option for some one that works on a lot of different things. I have tested it on a lot of big trucks, and it works flawlessly. I have also used it on regular automotive applications. I have successfully, flashed and reprogrammed about 10 Ford cars and trucks with this , and flashed and programmed several gm vehicles as well. It is not advertised as a tool to reprogram cars and light trucks because it will not reprogram all makes and models. But it will work on, Chevy,gm,Ford,dodge,and ram. I have not tested on any other manufacturers just yet.
    Great product


    I havent tested this yet, but diesel laptops deserves 5 stars for the great level of customer service. There was an issue with postage when it arrived in my country and diesel laptops had already followed it up in the background and made me aware of it.
