As far as I know ede65 is correct. Autel MaxiSys mini, will be able to do some coding/programing like MaxySys Pro, but it only will connect with Autel servers instead of the OEM Servers. So you always will be deppending in what Autel servers as.
I know that this features coding/programing, and software, in MaxiSys Mini will be close to 100%, like OEM, until the end of this year in brands like BMW, MB, HONDA, PSA, FORD, MAZDA, RENAULT, JAGUAR, LAND ROVER, at least.
But I always will prefer MaxiSys PRO. I think the J2534 box will make a difference in the future.
