Please post a picture of the board.
What is the model of the CPU? What is the flash?

The microcontroller is a tc1797-512. , I am unable to verify the details on the flash as I am unable to read it via jtag. Pictures to follow.

From what I can find out with the tools I have , Pcmflash "can" read this ecu via obdii pins on bench using an option within the software for "ford" , I have tried this method that does not work. , I have tried via ktag again same story didn't work. , there are some very exspensive tools which claim they can read this ecu all via obdii bench pins. They all seem to run on the same sort of lines using boot mode. And bench obdii. , that Is as much as I have found out so far.

I have ordered a TC1767 dev board and hope this can help me develop the software needed.

Tc1767 ? , I wonder how different it is to the tc1797. , too add I had investigated to buy a dev board for the 1797 , and its not very easy these days.

The JTAG protocol is the same. There will be some tool I can use to learn from.

To further some exploration I have purchased DAS programmer from aliexpress, it apparently can read a tc1797. It may include some sort of connection plan with it , or software , it's going to take a while to get to me so we shall see
