Not sure if I have anything to read it. I've got a DRBIII, VAGCOM, a MPPS cable, and other miscellaneous other electronic gadgetry from projects past. Will any of that work?
Either way I'm less inclined to fiddle around with it and wind up bricking the thing than I am sending it to GDE to have them do it. But I really am interested in knowing how it works and what stays with the TCM and what gets overwritten with KJ base code.
Interestingly enough the DRBIII lets you see hex address values in the TCM while it is online. It cannot modify anything in the TCM, but it is interesting as a read online function.
The DRBIII can write to the TCM for flashing updates. Watching the serial comms during an update might help understand the communication.
I suspect it is possible to "tune" the TCM by simple serial read writes to change hex tables, but I don't have the time to really screw with it.

I know very little about the TCM but I can tell you that Dodge trucks, some Cherokee's and the probably several other models use the same TCM with slightly different programming. I'm running a RAM TCM in mine. So, brick away but I suggest you do it on a more readily available TCM model.
NO CHEROKEE's use the same TCM as the KJ.
