paragragh 5 bill=yes it is your vehicle but it's their warranty as well-i bet if one signed off on warranty work-they'd allow pcm tuning

 

HI!... Stand alone FTW............

 

Well, My 04 is out of warranty, so Im tuning away!

Isnt there a "Law" of some sort protecting people who have mod's on the truck. Not sure what it's called, but something to the effect the dealer has to be able to prove that mod, caused the issue??? Not sure if Im on the right track here or not... SOmeone else feel free to chime in here!

On Second thought, I guess if they can tell it's been reflashed and a custom tune was installed it's there discretion to honnor the warranty.

Kind of like on our tuners if the sticker has been broke, and the module has been taken apart then they will NOT warranty any repairs.

Always something, give it time, and someone will figure out a way to cheat and get around this as well.

 

Josh,

When you say the IDS tracks changes, do you mean that the IDS actually reads the ECM and provides a time/date stamp that indicates when the ECM was reflashed, or do you mean that it is tracked in Oasis? I am just curious how they would track a timestamp in the ECM, at least one outside of a "Number of minutes" count that would provide an accurate timestamp.

 

So you're saying that once my warranty is up, Ford will hand me whatever equipment I need to tune my vehicle, or at least give me the information (such as Seed/Keys, checksums, tables addresses, programming routines, etc) so I can figure out how to do it myself? Don't bet on it.

Warranty or not, they aren't giving ANYONE the opportunity to twiddle their vehicle's parameters. Period. Maybe we could convince them that once the vehicle has exceeded the warranty, they can permanently "unlock" the PCM to allow some very basic software to effect changes to the parameters. Wouldn't that be a sweet idea? Oh... Ok... I'll wake up now. The dream is over.

 

i'm saying while it's your vehicle, to cya or cta -they want no programmikng done during the warranty period

 

Yes, all calibration changes are held in Mode 9 data, with VIN and other PCM data. The techs are "supposed" to place this in OASIS as well, but the PCM "keeps up with it". The "timestamps" include mm/dd/yyyy and a actual time(12:31 pm). But here is more info on the EEPROM:

The flash electrically erasable programmable read only memory (EEPROM) is contained in an integrated circuit (IC) internal to the PCM. The EEPROM contains the vehicle strategy including calibration information specific to the vehicle, and is capable of being programmed or flashed repeatedly.

As part of the calibration there is an area referred to as the vehicle identification (VID) block. The VID block is programmed when installing a new PCM as described under Programming the VID Block for a Replacement PCM. Failure to carry out this procedure may generate fault code P1635 or P1639. The VID block in an existing PCM can also be tailored to accommodate various hardware or parameter changes made to the vehicle since production. Failure to carry out this procedure properly may generate fault code P1635, Tire/Axle Ratio out of Acceptable Range. An incorrect tire/axle ratio is one of the main causes for fault code P1639. This is described under Making Changes to the VID Block and also under Making Changes to the PCM Calibration. The VID block contains many items used by the strategy for a variety of functions. Some of these items include the VIN, octane adjust, fuel octane, fuel type, vehicle speed limit, tire size, axle ratio, the presence of speed control, and four wheel drive electronic shift-on-the-fly (ESOF) versus manual shift-on-the-fly (MSOF). Only items applicable to the vehicle hardware and supported by the VID block will display on the diagnostic tool.

When changing items in the VID block, the strategy places range limits on certain items such as tire and axle ratio. The number of times the VID block may be reconfigured is limited. When this limit is reached, the diagnostic tool displays a message indicating the need to flash the PCM again to reset the VID block.

Each of the procedures described below use the Worldwide Diagnostic System (WDS). Programming can be carried out by a local Ford dealer or any non-Ford facility. There are other enhanced diagnostic tools that may have programming capabilities available. Refer to the manufacturer's user manual for details.

 

I certainly don't disagree with you regarding CTA over warranty issues. However, they don't provide me (the customer) with any options to either forego the warranty completely or even wait until the warranty expires and then make it so I can (relatively) easily adjust my vehicle. Even after warranty is no longer an issue, I'm still stuck with something I can't change. That bothers me.

 

Thanks, Josh... That is useful information!

 

yes- that's the reply was aiming at

 

Well done gentlemen, thanks for the info

 

Well I learn new something everyday. I don't agree with locking ECM cause I bought it I should be able to modify it anyway I want. You can keep track as much as you want, I understand this cause there are probably countless warranty claim cause someone over tuned the engine. But if I have a warranty claim they better be able to prove that the tuner did such damage. I guess I don't have much to worry about I have Troyer tunes and I trust his work, which is the only reason I went with him, and I have 2,500 miles until my warranty is out anyway.
