Yanking back out of the garage where its been since we moved the dealership in late 05.
Its freaking awesome i would sell my truck to own one all day. If they had a good A/C system.
Not the greatest pics but next time he uncovers it this week maybe ill snag some good shots of it.FairTax.org

You couldn't buy this car any other way then 4.6L DOHC Supercharged Tremec T56 6 Speed Manual 3:55 Rear Gear. There would be no need for different Computer Codes if all had the same software.
Dealers typically replace the sticker on the ECU when the firmware is updated. Example: The firmware for my Cummins engine has been updated a couple of times in the last five years, and each time the dealer peels off the old sticker and puts on a new one with a new rev level on it. Same engine, same electronic hardware, just new firmware.
Why new firmware? Because they learn things once products are released into the field. I'm in software development and I can tell you that firmware doesn't stay the same once the first product is shipped. We improve things constantly as we get feedback from customers, and we update their firmware when customers have issues.
This is true of consumer grade electronics these days, too. Apple makes firmware upgrades available for their iPods and iPhones. Wireless routers seem to have near-constant firmware upgrades. And so forth.
In the case of this EEC, they may have changed optimizations as (example) ethanol content has increased. Customer complains of this-or-that behavior in an area with high ethanol content, dealer looks it up and finds an ethanol-optimized firmware rev, and installs it at the customer's request. That's a change that Ford could not have accommodated initially because who knows what the US Congress is going to mandate as far as fuel changes {growl}. If the fuel changes are big enough, it will affect a subset of vehicles. Some subset of THOSE vehicles will have owners who notice. Some subset of THOSE owners will care enough to ask the dealer and get the updated firmware - and a new sticker with a new code. Now you have two basically identical vehicles, with two basically identical EEC's, but with different firmware revs. Precisely the situation you found on eBay.
Thus different firmware revs don't (necessarily) have anything to do with altitude, or region, or paint color, or size of the driver's right foot. They may simply be improvements developed later in the life of that car/router/iPod/whatever.
BTW, here's a partial list of Ford EEC firmware revisions and the vehicles to which they apply:

Since these 2 computers are for the same vehicle with no other optional gearing or motors or transmissions, If you look a bit closer at the pictures you will not only see 2 different computer codes but also 2 different part numbers. They will never ever ever with any parts of any kind change a part #. Also I would some what agree that they can change the sticker but I dont since the YDH1 is by far the most common Code for the 03 cobra. And we have numerous customers that are original owners and have never had a reflash.Last edited by 91Terminator; 11-24-2010, 08:37 PM.FairTax.org

Just trying to point out the possibilities.

Originally posted by WABoating View PostAny chance they revved the hardware? That would change the part number, and likely require new firmware too, even if the ECU worked exactly, precisely the same with the exact same engine/gearing/tranny. Hardware gets revised all the time for reasons of cost, sharing hardware with multiple vehicles to improve economies of scale, etc. This stuff happens mid-year, not just at model year boundaries. Just because it's different hardware doesn't mean it does a different job.

These cars were bought brand new off the showroom floor and have never been touched by a reflash.FairTax.org

ECU's rarely get revised and if they do they will not change a part number.
