Wasn’t really looking for ideas as much as I was curious if the aftermarket had any options. There are certainly multiple ways like pull a fuse, hidden battery disconnect, etc.
I guess I was thinking of the way the OEM JTEC works with the module in a Ram or Jeep GC where they communicate over a 2 wire network. If the module doesn’t get the unlock signal, it tells the PCM not to run and the truck shuts off after a second or two. Wondered if any of the aftermarket EFI systems could do something similar.
If multiple tunes can be loaded and switched on the fly, I could see something like this working. Just don’t have the experience or access to any of the systems to mess with it myself.
