I have stayed away from this platform for long enough and now I think I want to start learning more about it and maybe even help the tuning community out. The work that I've done on the P59 was a good learning experience, but there are not many people using that platform anymore. I don't really have any other features that I want to add so I think I'm probably about done with development of that platform.
I've seen the pictures that Tazzi posted, which will help significantly when opening the first one up. I'm hoping to be able to get the bin file pulled out of one of these and see what lurks within. It's probably going to take me forever, but I might as well get another project started before I finish the other 10 that I have going on lol.
I'll try and post as much information as I can find, but it seems like there is already some information out there that maybe we can try to condense into one place.
Here is some more information Tazzi posted:
It seems that maybe the latest U-Link NT from http://www.usbjtag.com could work with the E92 CPU (MPC56xx) Thread Here.Tazzi wrote:It may... or may not fire up again after the abuse I just put it through. It certainly was not designed to be pulled apart!
So our lucky processor is a: SGMPPC7241F8MVR 3M17W
Reading online others have labelled it a MPC5674.

And has 4mb of flash!
Looks like the variable length encoding (VLE) is usually favored in compilers even when using assembly to minimise the code size. I guess the next step is to see if she boots up.. and if so log a TIS write and take a look at the GM kernel.
I have used the USB BDM NT with some help from them and it worked very well with the P59. Hopefully the same can be said with the E92, but I'll probably reach out before buying a U-Link NT.
