Re: Ford programming Explained

Yea once they cover the 1st gen version of the computers I planned to buy it for a secondary option for flashing. PCM Flash works great, but 96-97 it can't do for some reason even though it's still the EEC-V era. I haven't dug into it yet, but it might not even support the CANBUS EEC-V computers whi...

Re: Ford programming Explained

This looks like a real interesting read, thanks for posting =). I heard about forscan wanting to add the ability to flash computers but I haven't followed it. Looks like currently the "1st gen" computers are still being worked on, but 2nd gen (sounds to be 2005ish through 2011ish) is what ...

Re: How to properly define a byte in code with tvrfan's SAD?

Yea if I was writing my own EEC-V code that's the route I'd go, however this is the stock code, there's some settings that aren't exactly meant to be able to be changed and those are effectively hard coded. When disassembling a file it would be nice to have the var name in the if statement so I don'...

How to properly define a byte in code with tvrfan's SAD?

I've been using SAD (Semi Automatic Disassembler) for a bit now and has been a great tool for what I've been doing in the EEC-V computers, linked below. https://github.com/tvrfan/EEC-IV-disassembler Currently the only thing I haven't worked out how to define correctly is hard coded values aka consta...

Re: EEC IV read write

Lol, yea that's why the chip stuff seems like it used to be really big for that era of ford computer and how huge it is for Moates Quarterhorse to just dissapear overnight basically. I got in the game months after they closed up :(. If you need to find an exact setting in an EEC-V computer some time...

Re: EEC IV read write

I mostly work with EEC-V computers, but if it's 95 and older, of my understanding, they are read only and would require a J3 chip if you wanted a tune from another computer running, or just get an exact replacement, if the part number is the same, being read only would mean it's code is also the sam...

Re: Ford ECM/PCM types

To add to the listing: 96-97 Taurus 3.0L (2 valve) - EEC-V (not sure which size though since PCMFlash doesn't read these ones currently) 98-03 Taurus 3.0L (2 valve) - EEC-V 216k - PWM 04-07 Taurus 3.0L (2 valve) - Should be EEC-V 216k - CANBUS but haven't validated myself Sable with the same engine ...

Re: Wanted 808/082 Engine loom plugs and pigtails

Yep, finding all the part numbers, which ones you actually need for the wiring you have, etc is a nightmare, then half the sites that supply them want you to request a quote instead of just letting you buy outright. Seems like the connector industry is like 20 years behind the rest of the world lol....

Re: How is the checksum for EEC-V calculated?

Yea that's basically exactly what I ran into, except it looks like your ending addresses all end in E instead of F? Is that the difference you've noticed, or maybe just how the software uses the ending address. Also, my findings on ALAPK is the same, it's the smaller checksum length. I probably shou...

Re: How is the checksum for EEC-V calculated?

Found another pattern, looks like early eec-v 4 bank computers had a smaller bank 1 than the later ones. Checksum is done in the same way, but just a different address size for bank 1. Checksum appears to be still stored at bank 1 0x200A EEC-V 216k (bank 1 treated as 0x8000 long starting at 0x2000)....
