"Manual" ECU Flashing - 6.4L ECU Thread
I notice that there is no real discussion of tuning outside of using dedicated diesel tuning devices that marry themselves to one VIN number.
I would like to start discussion around what it takes to remove the ECU from a vehicle, disassemble it, dump the stock rom from the device, modify it, and flash it back.
This, of course, brings us close to the dangerous topic of using a licensed tuner product to flash a vehicle, extract the modified firmware via manual dump, flash back to stock, unlock the tuner device, and manually flash the tuned file back. While I do not condone this behavior, it does strike me as more of a violation of the manufacturer's terms of service than actual copyright infringement. Either way, let's please refrain from discussing this topic in this thread.
With that out of the way, who here has any information on the Ford ECU?
In addition, how much do we know about these tuning devices? Do they communicate via serial? JTAG? SPI? Is the ECU encrypted?
