Sometimes you can find the SAE Standards, like J1850 and J2178, floating around the internet.

PCM: 0x10-0x17

Off-Board Testers / Diagnostic Tools: 0xF0 - 0xFD

All Nodes: 0xFE

Null Node: 0xFF

Pin 13 of the DLC goes to pin 13 of the PCM which is labled as "Voltage supplied at all times (overload protected)". I'm guessing that the DLC pin 13 is used to power the PCM when you want to flash...

The EEPROM is not a 28F010 but since it has the same package style and a similar pinout for pins like power and GND its probable good place to start.
I tried to read the EEPROM in a programmer...

You need to know the period of the PWM to get the duty cycle in percent.
duty cycle/period = (24ms)/(?) = duty cylce %.
The period is the inverse of the PWM frequency. 1/Freq=period.

If I can learn how to reliably reprogram the EEPROM on the EEC-V I might not even bother with an adopter to plug into the J3 port.

CPLD or Coprocessor???

The design kit came with the parallel download cable and the ISE software.
There is also a good amount of proto-typing space for thru-hole parts. 8)

I have more then enough electronics parts laying around to build one. I bought a xilinx demo board(XC2C256 & XC9500XL) so I could teach my self how to program in VHDL, but I haven't had much time...

Do you have the rest of that List file? Or maybe some other ones?

Yeah, That fixed it.

When I open or download the file its just displays garbage like this:

Since ford used a special EEPROM getting the data through the J3 port isn't as straight foward as it would be on like a GM. In order to program the EEPROM you would have to sniff the 30 I/O pins on...

I assume you guys at HP tuners know this now. So does GM put the OS in the EEPROM or the µController?

What kind of ford info do you have? :secret: I'm having a hard time finding usefull stuff, because there's not much out there. :banghead:

Is the Ford PID list a complete list?
Can I get a copy if it is?

thanks,

You can buy usb to serial converters.

Does anyone have any info about the 4 banks of the flash rom on the EEC?
Which banks holds what? ???
