I had saw you posted about Ford tuning software, figured you were a Mustang or Lightning DIYer.

You definitely should get a Cobra. The 03/04's are a blast!

Awesome! Thank you. I think my email is listed. Please list the year/appl for each binary....so I can look up the engine specs.

I will try to help out with the tables involving MAP. If I were you,...

I take it you've seen it? :) Very cool huh?

1998WS6, what is your experience level? Do you own an EEC-based vehicle? Have you done any tweaking to it?

Wow, this thread has been dormant for a while. Here's my status....

-Decoded most popular items in most EEC-IV, EEC-V ECUs (Mass-air stuff, timing, etc)
-Planning on using Craig Moates J3...

I'm a J3 connector guy, but from what I've seen and read, yes the EEC-Vs can be reflashed thru the OBDII port.

In combination with your pass-thru device, you can buy a subscription and the...

I should probably focus on figuring out the memory addresses for the L1C, rather than playing around with reading the 4-bank Autologic burned for another ECU. But the read encryption is puzzling. I...

Can somebody post a binary for a HC11-based ECU from like a Camaro? The newest/last year of the HC11 would be preferred.

I'm a Ford ECU fan, but would love to disassemble and look at an HC11...

That makes sense on the banks. Does all the calibration data fit in 1 bank on the newer EEC-Vs (99-04)?

Actually reading the Autologic chip would make sense, if a person had documentation on the...

Uncleton, I believe the Autologic chip can hold up to 4 banks, but my 99 ECU uses two. Not 100% sure though. It is a potted-type chip, black in color, and looks like they cut off the bank select or...

Uncleton,

Found a picture of how Steeda flashes. Looks like the Rotunda tool they use is simply an out-of-car OBDII flasher. Nothing special. I'm wrong on them using the J3 port. Their tool...

Uncleton,

Isn't there a Ford/Rotunda tool to flash via J3?
I'm lacking on info on this, but I thought that is what Steeda and Saleen use to reprogram ECUs.

If you would like, I could try to...

Uncleton,

Hooking in 8K of RAM. We may share the same goal.

The MBUS is a pretty neat little world. I better had polish up on my VHDL skills.

Jfunk / Uncleton,

Doesn't Ford like Intel memory?

Maybe with some help from PCB traces to the MCU, you could decipher the Flash?

I would suggest learning about Intel 28F010 Flash.

I'd...

Jfunk,

No need to burn too much time on the ECU pics. If pics turn out OK, that's cool, if not, oh well.

My J3 ROM reader is pretty simple. Based off of Andrew March's parallel port circuit...

I can post a reply if this thread is still alive and kicking. :)

Jfunk,

Do you have the hardware to extract the EEC-V's ROM via the J3?

Would you happen to have any good data on the J3? I have Tom Cloud's papers on the EEC-IV, but can't seem to find anything...

Uncleton,

That is a very good idea as far as reprogramming the CPLD on an existing J3 adaptor.

Sounds like remapping the entire ROM would be much easier.

I'm concerned with timing you...

Uncleton,

By "high-end", the logic density seemed high on the J3 adaptors floating around. But the encryption explains it; most commercial adaptors probably do not want to be easily rewritten.
...

Geez Screamn03, you pretty much nailed locating some ECUs! :cheers:

Were you planning on bidding on either? If not, I'll bid on both, but if you wanted one, I'll bid on the other.

Thanks for the pic, W. Why is it necessary to use such a high-end CPLD?

Do you have any data on the J3 port itself that you could share? How is the J3 bus different between the EEC-IV and EEC-Vs?

Screamn03, try this:

Try www.moates.net for your friend's 94GT. I had one of them, a 5-speed. Thats a good Mustang, full of potential. So Paul never...

Screamn03, I downloaded that Predator software. So basically, it's just a utility for sending files to/from the Predator handheld tuner? That's cool though. You may want to consider Port monitoring...

Screamn03, do you have software to transfer the file from your computer to the Predator? If it's freeware, can you let me know where to find a copy?

Sorry to waste time about the shiftlight, I...

So, Screamn03, from your Predator tune, your EEC-V is code YDH1?

Can I download the Predator software to view your file from somewhere?

A little off topic, so the new 03/04 Cobras have...

Screamn03, that did help. I've been there a bunch of times, but never noticed the J3 adapter schematic that listed the J3 pins and lines. That helps a bunch! I've got an ECU (off of an old Cougar,...
