HiWilson,
You can program the ECM with Maxisys Pro. You do not use the tablet at first. You use the VCI connected to your PC via a USB cable. You need to install the driver for the VCI into your PC first. It is on Autel's site.
Then you need to go to techauthority.com and purchase a subscription. After you purchase the subscription, you need to download and install Chysler's J2534 program from techauthority
Now here is the screwy part. You probably will not be able to download the file you need to program your ECM. You select the file that you need a click to download it and nothing happens, no download.
There are a couple of reasons for this. The first is you must use EI 11 only. No other browser will work.
Next, you MUST have a certain version of java in your PC. Only 1 version of java works. I can get you it if you need it.
Next, if your running Windows 10 or XP, and you have it to the point that your file downloads, you will then find that the file is downloaded to the wrong path! That is for the 2009 and back models.
I can help you sort it out. I spent 6 hours getting the Chysler J2534 program to work and if java updates, it will work no more.
I would turn off any firewalls or virus scan programs just to make sure those don't cause problems too.
Let me know if you want help getting it working.
