Bests & Worsts Reviews from Amazon

I chose this unit over the Bluetooth/WI-FI versions because of the big cost savings - the cable on this unit was plenty long enough to connect to my laptop while sitting in the drivers seat. This item worked perfectly. I am rating only 4 stars because of the terrible instructions. The included instructions were printed on both sides, one side for one model, and the other side for a different model. I never did find a matching model number from either on the actual product so I could download the correct drivers. I finally just downloaded all from the website link provided, and it worked. I used this on a 2015 Ford F150, along with their free FORScan software. There is a switch on this unit - again, no indication in the instructions which position it needed to be in. To help anyone planning to use this in the same manner, I am offer the following tips that I learned through trial and error - hopefully it will save you a lot of time! This unit plugged-in to the port on my F150, located under the driver’s side dashboard, with the label on the unit facing up, and the switch on the right side. When first trying to connect with FORScan software, the switch must be in the right position, otherwise you will get an error message. The software will then begin to load the profile of the vehicle, and it will ask if you want to load a known profile. If you click on "yes," only some of the modules will be shown. Click on "no" and FORSan will scan your vehicle for the installed modules. During this process it will stop and a message will appear: This vehicle may contain MSCAN modules. Does you ELM adapter have HS/MS CAN switch? Well, this ELM adaptor has a switch, but there is no reference to the switch in the instructions, so I clicked on “I don’t know,” and only the basic modules were shown. Later I tried again, and clicked on "yes." The software then instructs you to set the HS/MS CAN switch to the MS CAN bus position and click OK. Well, it turns-out that is the switch on the unit, although there is nothing in the instructions that provides that information. Flip the switch to the left position, click on "OK," and the rest of the modules will be found and available for modifications. You will then get a message asking if you want to save the profile. When you do, be sure to give it a unique name, otherwise the name appears the same as the original one - I couldn't tell which was which. Hopefully this will save you an hour or so of experimenting. Although most of my comments are based on using FORScan software with the unit, I suspect it will be similar with other software, as well. Mostly identifying what the switch is and the position it must be in is key. Seems like it would have been a simple matter to include that in the instructions!
