I've loaded all I have on the EEC-IV and EEC-V EECSucka too github;
https://github.com/OpenEEC-Project/EECSucka-Archive

The information is relevant to building Moates alternatives.
Looks as though Andrew March and others were going the CPLD route before Moates products became available.

Awesome! J3 emulator, Xilinx programmer, and eecsk501 source code, forked and downloaded thank you sir!

Share and share alike.

Here's something else that may float your boat...

I would sure like to know more about that internal EEC4 Rom Chip you have, could you send me a bunch of close-up pictures. I would like to know more about the BURN2 custom firmware, and the Ziff socket adapter pictured in your post. I'm curious if you have the firmware as a separate file or if your special BURN2 came shipped with it already loaded? Do you solder that replacement chip into you EEC after programming it or solder in a socket or even ziff socket? I've been intrigued with the old ford EPROMs in the EEC4 for a long time and could not justify jumping down this rabbit hole to learn how it works because I though well when I get more ready, I just order up some stuff off the Moates website.


efloth/wwhite/sailorbob/ Anyone else

I've got my bread boards out and have bought a bunch of electronic junk off Ebay lately including some CPLD dev. boards as well as the JTAG programmers for them. I would also like to find someone with the adapters for the BURN2 to program the F3V2 chips as well as the adapter with that ribbon cable to read out the EPROM of the EEC4. I think those adapters are the F2A and F2E but I'm not sure. I would like to copy these as well as get PCBs made and share the Info by posting Gerber PCB files incase others want to assembly any of this.

I attached a picture that shows I'm motivated right now. Let me know your thoughts and if you have the time and desire to help me copy some Moates stuff for the relatively small group or EEC4 guys out there (maybe it's not that small). I don't think everyone is ready for Holley Sniper upgrades and the like.


Thank you

Cool! Are you focused on re-programming the factory EPROM or developing your own F3V2 style device? This link has the pinouts for the factory EPROM.

I'd say a jaybird replacement would be amazing: It programs J3 devices natively:

Both although anything I can come up with would mostly be copying Craig Moates, Andrew March, Kevin Timmermann, Tom Cloud and I'm sure a bunch of other Ford enthusiasts as well as a few unscrupulous Ford engineers. I think it may be possible to UV erase the chip in circuit and program it. There is an offset that has to be set along with the binary, but this would most likely be just a learning experience. I would much rather make a modern replacement ROM like what "xd4.1efisc" posted on page 5 in this thread. Understanding the old Eprom and more importantly the behavior between it and the CPU would help understand how the F3V2 and Jaybird work. I bought a neat little 16 channel DS logic analyzer and I'm learning how to use it still. Can you post some more pictures of the Jaybird and some shots of the back too.

Anyone who has Moates hardware within reach please send close-up pics of anything that might be useful.

Thank you

I'm using all the documents available to create the tools.
Specifically: EEC-IV Pocket Reference, EEC-IV Custom Circuits Integrated Hardware and the EEC-IV Software Manual.
All information about 8061/8065 chip architecture, memory, programming, J3 DCL etc is there.
I have Arduino Mega + RS485 working with CART/UART DCL, just had to write my own software.
Going to be connecting it to J3 soon.

I'm going down the Arduino route for testing, don't really need any other hardware.
Once the software is 'perfect', I will then think about what hardware components are feasible, scalable and future proof.

ps. Digi-Key just shipped me 10 female J3-Port connectors. Took 2 months.

wwhite,

That sounds awesome, I've been digging around the same documents, a couple githubs (one by JSA), and Internetarchieve.org. I ordered a couple J3 straight and a couple of 90-degree connectors from random evilbay places. I can wait to see what you come up. I also would like any closeup photos of Moates Jaybird front and back as well as the F2A and F2E adapters for the Moates Burn1 or Burn2.If anybody can post them here or PM them to me. The more I study this stuff the more I realize how closely we are following in the footsteps of enthusiasts from 20 plus years ago. Furthermore, I'm so impressed by Moates' design work and how compact their stuff is. I'm assuming Craig Moates was a computer nerd/motorhead/electronics PCB engineer/genius. I'm curious if this work was really all his, I'm sure he had all the same info we been digging thru but still I'm super impressed. I'm also curious how much soldering and or assembly work the Moates crew did in-house or did they have it all assembled at the PCB manufacturers?

Keep up the good A9L and other GUFX lifesaving efforts.
Thank you

I still have not installed my quarterhorse if pictures of that would be useful.

I finally got a used Quarter horse, I had to buy it from a guy in Texas and send PayPal and trust him to send it. I was thinking for sure I was about to loose 250 bucks but it arrived.

So although I appreciate the offer of pictures for that I’ve now got one of those in hand.

Thank you
J.W.S.
