Hi everyone, I am trying to connect to this Motorola MCU on my engine module. I only opened this module so I could see what processor it was. The one I want to read and flash is not going to be opened up like this. I only have the option of connecting to the 12-pin spot where the vehicle harness plugs into (Power, CanHi, Canlo, Ground)

The diagnostic software for the manufacturer of the machine reads it just fine, but doesn't allow editing the file at all. This is how it is setup now. What software can I use? Keep in mind what I want to edit will be in a closed module, so a PICkit will not work. Here is a layout of my setup.

You are pissing in the wind my friend. I think you will be hard pressed to find anything to read/write this module. Also, I am curious what your actual end goal is here? Is this not a carbureted 2-stroke sled? What will you be altering?

TIming curves, and yes 2-stroke. I know for a fact the manufacturer was bench flashing these. There has to be a way.
