 i read tht  you could do GM ECU replacement and programming in older versions but after GM update version 5 on maxisys, no more GM programming. by mistake i updated my GM version too so i know i wont have that feature and i never saved old version too in my computer. i wonder if one of you out there still have older version and some how can email or send me the file i would really appreciate it. i belive until version 4. you could have done programming on GM.if someonne is close by toronto i am willing to travel too. thanks

You can use your j2534 unit as any other programmer with a laptop. Bmw is supported
for programming and some ford. They will eventually have it for all makes. So there is
an advantage to having the Autel pro. I program all the time and has worked with
everyone I've done. I have done at least 150 so far.
