This is probably the reason that the decision was made to "burn" the VIN prior to shipping.
The dealer can apparently initialize the stage I PCM with the proper VIN AFTER it is installed. The emphasis on DIY installation, with the VIN burned in before shipping may have been intentional; to shift the focus from a dealer supplied / dealer installed accessory to a customer aftermarket purchase and either customer install or customer request of the dealership to install an aftermarket part.
At any rate, the disconnect between Mopar Performance and Chrysler sales/service outlets seems to be a planned one.

What if you order the Stage I and do not install it? Is Chrysler going to void your warranty just because you purchased the kit?
No, as I mentioned earlier in this thread, purchase does not flag your info. The VIN is merely to keep the SKIM from crying foul.
Don't you understand that the only reason they need your darn vin is for the security system and the mileage for the odometer.
See above. The SKIM is a part of the overall security system. It is what inter-reacts with the key transponder. That is what I tried to explain in an earlier post.
The dealerships can not,as of yet,program the 2004 pcm's.The vendor who produces the pcm programs it!
Actually, the dealer can write the VIN once the PCM Is installed in the car. The Vendor that MPP is using now to code them is the only place capable of coding the PCM out of the car. At least, that is the way it has been explained before.
Why do you think they are sending new pcm's for the 5200+ misfire problem, because they do not have the software to update the 2004 pcm!
The TSB states it is a hardware issue that affects a certain range of PCMs according to build date and transmission. I believe it will still be the 2003 PCM. The 2004 PCM is used in the Stage I upgrade, as well as 2004 production. According to the dealer I talked with, you are correct concerning their inability to FULLY access the 2004 PCM. They say it will be December before they have the gear to do so. In the meantime, the DRBIII seems adequate to address the 2003 PCM and accomplish mundane tasks (like writing a VIN) on the 2004 PCMs .
They have swiched over and the 2004 pcm is a completely different design ecu. It does not contain block mapping, but uses constant learning algorithmic calculations(more than simplified).
Are you saying that they switched from Speed density (look-up tables) to a sensor based cause and effect (Mass Air Flow) system without changing the engine design to incorporate a Mass Air Flow sensor?
I think is more likely that the 2004 PCM is faster (either from going from 16 to 32 bit processing or increasing clock speed) as well as having expanded memory in both the EEPROM and the available RAM needed to process a larger look-up table for the speed density system that Chrysler uses. Wider calibration ranges create the need for a bigger database to catalog the possible responses. This is what the Speed Density system relies on.
In the near future the dealership will be able to set the vin in your pcm. Most newer vehicles when replacing any ecu needs to be "coded" with the correct vin and milage for the vehicle before it will become operational, it then will communicate with the other ecu's in the vehicle and determine the proper mileage and some certain parameters.
[b]Close, Many of the early problems with bad VIN coding were corrected at the local dealer; provided the PCM was installed. The dealer can't code it off the vehicle, but has been able to do so via the diag link when it is installed.
