I'm not sure about the heating issue. I have never really checked the heat on my 16024 or 16018 while programing it, but that does sound wierd. I'll try and pay attention the next time I mess with it.
I also have never had a problem with the auto programaing mode. Always worked fine. I can say however that there doesnt really seem to be a need for the auto programing mode. I havent been able to tell a difference from beofre I used it to after I used it. It seems the only thing it effects is the brakes which seem to work fine for me anyway, the drag brake which i dont use and the "non-freewheel" mode which I dont use either.
As far as the shutting down goes, I have run into that consitently with both my 16018 and 16024. It starts to happen as I get around 2/3 of the way through the pack. I eagle treed it to find what is happening and it appears that the LVC is kicking in at a very high setting. (something like 3.4v/cell) MGM says that the LVC is set to kick inat 3.1V/cell. I have not found a way to disable or change the LVC voltage either. I asked Mike about it at the bash and he told me he hadnt run accross that problem. But I have in both of my MGMs. If you set it to "race mode" it will not happen as it disables the LVC all togher, but thats no good either for fear of toasing the lipos. Setting the spool up timing to a higher number limits the amps that the system draws and seems to control the problem for me, but like you said if you want to go out and do some stupid wheelie action it does become an issue.
It just looks like the LVC on the MGMs are much more sensitive than most other ESCs. I have never had a problem like that with a Quark or MM. I can say that I did see similar issues when I hooked the Li-Saver that Mike sells up to my BK12020. It behaved similarly to the MGM LVC.
I wish I could offer you a solution but as of yet I havent found a total soultion. It seems to me that the real soution would be to have lipos capable of never dipping below 3.4v/cell. All of my lipos are 20C cells, but I just got a set of 25C cells to test. I'll see if they perform any better. If you figure out a work around please let me know too. I have been puzzeld by this as well.
Do you have an eagle tree that you could hook up and see if you get the same voltage reading as me when it cuts out? For me it seems really high and like I said, MGM says the cut off is set for 3.1v so something is not jiving. Id like to find out what voltage yours is cutting off at.
EDIT: You should be able to just plug the USB COM+ into the ESC plug that goes to the radio. Thats how I do my 16018. The other cable is just so you dont have to unplug it from the radio.
I can't decide if its more fun
to make it...
or break it...
Silent...But Deadly
