The dealer just reflashed my computer and I don't like it as much as the original flash. What can I do to change it?
The truck is an '04 F-250 6.0, engine build date is January '04.
Thanks

 

You cannot go back...however which flash is it...number wise

 

Yeah, you already said that. Now tell me what I need to reprogram it myself.

 

The closest you can come to reprogramming it yourself is to get a Predator from DiabloSports or have a custom program written.

 

Did not know I already said that

 

So the original program is nowhere in the dealers archives of programs? Do they not keep any of the old flashes?
Thanks All

 

No they way Ford designed the computer you cannot go back even if they had it,
.... now with that said I have heard the the engineeres have done it back at the factory, I was told for testing purposes only...makes you wonder why they would not for us...

 

It can be done. But it takes some "fooling" the program. The program apparently looks at the revision number and will not accept a rev that would have been in the future. Ford is not going to do a backward revision. The revision was developed to fix a known problem. They won't go back.

 

I know they can "force it" so to speak....but for us poor customers...Steve sure wish we could figure that one out.

 

Sorry Saxon! I too have an Jan 04 and hopefully it will never need a reflash. I like it the way is and can live with the few very minor inconvieniences.

 

My "guess" is that the truck's computers would happily accept a flash to the older version but . . .

Either some form of configuration management is built in to the diagnostic computer at the dealer where it checks to see if the current version in the truck is newer than than the flash they are trying to down load, or the loader in the truck may do a form of this checking too - though I suspect not.

I would be that at Ford service centers where the techs and engineers spend time scratching their heads and other areas wondering about what's causing some issue, that they flash the truck fowards and backwards all the time. Probably just a check box on a dialog box, or a -xx option on a command line or something like that.

Most likely the can't go back to a previous version restriction is there to protect us customers from service techs that don't check to see if the version that they are trying to download is the latest or not.

I would bet a doughnut that they can do it.

Let's say your truck was out of warranty and you left explicit instructions not reflash your truck and they did perform this unauthorized repair. Since there are laws against this kind of thing, you could wave about a letter from a lawyer, and presto somehow they would put the truck back to the previous version.

 

I know for a fact they can do it, however...I was told something would freeze over before they ever did it to a customers truck

 

My '04 was flashed for the first time about six weeks ago. At first the mileage and power was poor. Lately, the mileage has improved along with the power...still real noisey with the PI turned off...Is this common afer a flash or is the truck just breaking in after 11K miles?

 

Yes, mine is a lot louder too now at idle speed , in gear or not. Also lunges into gear somewhat and that was never noticeable before.
Doggoneit.

 

Saxon, you may have some other problem. Harsh engagement is a symptom. Here is a service bulletin from Ford:

Harsh or Delayed Forward or Reverse Engagement:
This could be caused by a sticking line pressure control (PC-A) solenoid. Typically the line pressure will be fluctuatiing wildly (up to 500 PSI!). To service, first remove and insdpect the external cooler line filter. If it contains fine gray metalic debris. If metal is found, the source is most likely a defective revese planetary pinion shaft that is coming out of the carrier and contacting the case or adjacent components. The transmission will need to be disassembled and repaired as needed or replaced. Broadcast Message 3250
If little or no debris is found replace the line pressure control solenoid with P/N 4C3Z-7G383-AA. Broadcast Message 1586/SSM 17874/18051
This repair will require removing the solenoid harness, so a new harness sealing o-ring (P/N 3C3Z-7Z276-AA) will need to be installed. In some cases the solenoid body will need to be removed from the trans to remove the harness and solenoid. In this case the solenoid body gasket (basic P/N 7C155, trans tag number needed) will be needed as well. Note: Do not loosen the 10mm head bolts on the solenoid body. Only loosen the 8mm head bolts.
If the solenoid has been replaced and the condition it still pressent, suspect a contamination issue of the solenoid or a sticking pressure relief valve.

And by the way, I checked with some diesel techs. If your engine was built starting with Oct 1, 03 then you never had pilot injection. EGR strategy was used to quiet the idle.
