HD Rumble in the Rockies - Chevy wins

I like where we are going now! Got any more pics of the Bronco????

ill check but its not my project so i dont have many.

[91Terminator]

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.

[Timmy!]

That Bronco is sweet man! Thanks for sharing the pics with us!

If there is no different software then how do you explain this????
Computer Code HSF0
Computer Code YDH1

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.

They're the same hardware (looks like both are EEC-V's), but they've been flashed with different firmware - one an earlier version, the other likely a later, better, updated version.

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:

Hope this helps!

Nice body work on the Bronco. My buddy had one in high school that was really nice. That it is until he rolled it. It still drove but, it was never pretty again. Cool trucks though.

Well i would agree but:

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.

Ha ha that thing has at least 50 lbs of bondo on it LOL those broncos are known for rust. It was done in our shop and painted in our shop by a friend lol not even in a booth. Has yet to be wet sanded and buffed you can still see sand paper marks all down the side. But after the wet sand and buff it should be pretty dang nice.

Check it even Akon knows whats up Bronco's are pimp baby!!!!!!!!

Any 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.

Just trying to point out the possibilities.

What is the word from the ford dealership?

Havent Called cuz i told you there is no point in calling for parts and info on the 2011 he wont know enough yet. They dont even have service manuals in the service department yet.

Nope nothing since they have owned the car has ever been done to there ecu's. ECU's rarely get revised and if they do they will not change a part number. Ford Motor Company does not just randomly change part numbers otherwise they would not know what computer is what, the part number will always stay the same from the day its built on.

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

Ya, I didn't say any thing about the paint. J/k. Nothing a fat wet sand won't cure.

[Nobody]

I'll wait till Toyota comes out with a diesel truck, cause I have enough headaches.

Perfectly possible, if one received the previous model ECU and the other received the then-current model ECU.

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

So if they built an updated ECU, the old and new units would have identical part numbers? Really? Sounds like a stockroom nightmare. I find that very difficult to believe... they would need some way to differentiate between old and new ECU's.
