First experience of using V91 Ford VCM II Diagnostic Tool

About two weeks ago. I have a trouble for selecting a VCM II TOOL for my 2011 Ford E350. I don’t know where I could find one for good price that will indeed work on my vehicle. I read some information on OBD2 tool shops and blogs, and still don’t know which exact VCM TOOL will work, because I saw different versions, such as V86 and V91.

Just as follows:

V86 VCM II Diagnostic Tool for Ford

V91 VCM II Diagnostic Tool for Ford

I was reading other forums and people said they used V91 VCM II Diagnostic Tool. Finally, I bought it on eobd2.fr. I have used it for one week now. I will share you the tips for Ford VCM II V91 installation.

Ford VCM II diagnostic tool software has been already available to the newest V91. You can read below tips before you install the Ford V91 software:

1. There is only one chance to install the V91 software on one computer. Once install the V91 software on one computer, it will not get the prompt “trial for 3 days” 3 days later, which means that we failed to install the V91 software on this computer. In such case, we can’t install the V91 software on the same computer again.

2. VCM2 V91 software does support WIFI. Also, it is available to connect via OBD Port.

3. After install V91 software and frozen software on one computer, that computer can’t install any other software.

4. After install V91 software and frozen software, if we can’t continue use them after 3 days, please reverse the computer time to be the day you installed the software. Then we can go on to use the software normally.
