That's correct. Unless it's an EPA certified configuration of tire rev/mile and axle ratio-they cannot and will not do it.

So what I think you're saying is: That IF my PCM can be programed for the changes I've made, but Ford Service may not be allowed to perform the programing, then possably an other "programer" may be able to set the parameters I so desire. ?? (that would be a clue! Don't go to the dealer service department for this procedure.) OR, is the PCM precalibrated (or limited) to accept only thoses changes that are approved by EPA/Ford?????
According to my 2003 Powertrain Control/Emissions Diagnosis Service Manual(mind you it covers all the 2003 cars and trucks), the Vehicle Identification (VID) block of the Flash EEPROM (Electrically Eraseable Programmable Read Only Memory) area of the PCM sez:
"The VID block in an existing PCM can also be tailored to accommodate various hardware/parameter changes made to the vehicle since production."
It goes on to say :
"The VID block contains many items used by the strategy for a variety of functions. Some of these items include the VIN number, fuel octane, fuel type, vehicle speed limit,tire size, axle ratio, the presence of speed control, and FWD-ESF vs manual shift on the fly."
The paragraph concludes by saying: "Only items applicable to vehicle hardware and supported by the VID block will be displayed on the scan tool."
The section ends with this:
"A PCM which is [all ready] programmed may require changes to be made to certain VID information to accomodate vehicle hardware. Refer to PCM/Module Reprogramming on the scan tool."
So how does,
"The VID block in an existing PCM can also be tailored to accommodate various hardware/parameter changes made to the vehicle since production"
Jive with:
"Only items applicable to vehicle hardware and supported by the VID block will be displayed on the scan tool." ????
All of this suggests to me that the solution to what I would like to achieve, is in re-programming my PCM. IF so, HOW???
Sorry if I'm beating this into the ground, but I'd like to be sure befor I go to a Speed signal pulse modulator. Thanks, Rob.

Ford Service Techs can access ONLY the VID block,and nothing else. The PCM has a very wide range of tuning capability-Ford uses some of the identical same PCM modules for several vehicles,with just minor software changes. For example..my '05 F250's PCM has capability for electric fan control,but it's disabled from the factory via a softwae switch because my truck doesn't use one. It also has a very wide range for rear axle calibration, and a tire revs/mile-MUCH more than you'd ever use in the real world. Problem is...none of these "calibration level" items are available for the service monkeys to change-they'd probably screw it up anyway. The only things they can do to the PCM programming are "canned" flash updates, and VID block changes within the OEM EPA approved configurations.
If you want to change those items,you must get an aftermarket flash tool and have somebody that understands the control system software to make a calibration file with the parameters setup like you want.

Thank You Johnny, I was suspecting something like this might be the case.
If I get you the catch number, will you be able to tell if my PCM can be "flashed" to the changes I've made? Rob.

I can check to see if the parameters are there for calibration or not.

My SCT SF asks for tire revs per mile and rear end gear ratio to correct the speedo.
I think an SCT dealer could set-up your E-series up with an Xcal and get the speedo reading right. Could put it on the dyno and pic up some more power too.
I have an 02 Super duty xlt, its shot plugs out 4 times in the last two years, 3 this year alone, I want to swap out 5.4L and put in an older for v8, trans, & transfer case. Is there a way to remap, or reconfigure the pcm to not monitor or look for the stock engine systems so I can run a new powertrain system w/out losing everything like wipers and lighting?

The PCM controls the powertrain only. NOTHING more. ALL of the electrical system is independant of the PCM minus the underhood engine control system. As for changes to make an older engine work-It can be done,but you'll have to keep in mind things like crank trigger,etc for ignition function, and then there's the issue of being Fed Emissions legal. If you live in ANY state that has emissions restrictions at all, you cannot do it if you want to drive the vehicle on the public roadways. Then there's the transmission-Windsor pushrods have a different bellhousing, so you'll be buying another trans too. Besides,the modular engine is far superior to the older pushrod Windsors in terms of overall efficiency, power and durability. Some don't agree with this,but it's a fact.
I agree, the modular is far more effeciaent. My impression in my particular vehicle , I'm not impressed. My buddy as the same truck with 6 spd, we switched trucks one day, and the difference was unbelieveable. I just got a bad motor. I've put $3700. this yer alone, and now they say my block is bad. I dont have $6250. for a new motor, but I can get the older 460 or 400M, which I love that motor, along with a 460 ZF 5 mannual trans & transfer case. I can make the engine work, it just seem in the diagram that the lights, wipers, and almost everything else runs to the pcm. If IU disconnected the engine harness from the PCM, and rotated the key to the on position, I should have full use of everything, and from that I quess I could determine if it would work or not, right?

You're probably looking at the GEM module or the CCRM wiring-the wipers, etc do NOT go through the PCM. The engine/PCM harness has only the powertrain controls in it.
$6250 for an engine-you're looking in the wrong places.
2003 5.4L w/o EGR 44K miles-$1800 located in White Hall,WV
There are fair deals to be found on complete engines-IF you look around. Car-Part.com--Used Auto Parts Market usually has a large number of listings.

Put steel inserts in all the plug holes and be done with it
Did you ever have the plugs changed? Sounds like someone really screwed something up to have that many plugs go out the top ...

Yeah the first time it happened, ford wanted $2700. to put an insert in the one that blew out. We had a cylinder head shop pull my heads off and put the inserts in all 8 holes. As far as I know, those are the original plugs from the factory. with exception to the ones that blew out. It lasted a year and a half. Blew out second, took it to Ford, they installed a second bigger steel insert, lasted month & half, shot out 3rd, this time we replaced cylinder head, lastede 1 month then blew out 4th on the other side. They claim to hear a knownk, and bore scoped the cylinder. They also claim that it sucked a piece back in and it worked the piston, cylinder wall, as well as the head. At this point they said $6250. for a new ford motor. With the luck I have had with this engine, I'm hesitant at least to shell out another $2000. and chance another run of blown plug. Besides, my 5.4 only getts 9 mpg average. the truck is to heavy for that automatic and 3.73 gears. The truck drop down to grab gears empty, rolling up a long 5 mile strech of level highway. It dosnt have enought power to keep the momentum up. I fell that if I put a better drive train in, it mpg will increase, it sure cant get much worse.the Triton have burnt me pretty good on this engine, 4 times in 2 years. i need a permanent solution, it like russian roulett with the ignition key. I dont haul much at all, I baby my truck, I love it emensly.
If the inserts are coming out, they didn't do the job right.
Did they use the "Ford supplied" inserts? Or something else like Helicoils?
I can understand popping one plug, but multiples AFTER doing the inserts? VERY fishy...

i can only hope so, we used the same inserts Ford uses, and he had repaired many before mine and was quite familar with teh issue. I appreciate all the feed back. I think I just got a bad engine. It happens. I love the truck and want to keep it. I want to find a permanent solution. I need to do some more research into the swap out. I know some guys are dropping in dodge cummins 5.9l into ford super duty and mating them up to ford drive train. There must be a way to fit a 400M in there. We I have to go for now, thanks, I really appreciate your knowledge. Its nice to know thyere are places to go that people can share openly what they know, take care.
