I'm not sure if you guys are aware of this but at www.mazdatechinfo.com, under the Mazda Module Reprogramming, they have PCM Reprogramming code. This is their description:

PCM Reprogramming Codes
PCM Reprogramming codes allow subscribers to program electronic modules on applicable Mazda vehicles (sold in the United States) to the latest calibration level.
See Application chart (PDF version or HTML version) for vehicle coverage.
The subscription includes:
Access to a downloadable software application that you can install on a PC.
Access to a list, arranged by vehicle, of the latest calibration information for emission-related modules.
Recommended Requirements:
Processor – 500 MHz
Memory – 128 MB of RAM
Available Hard Disk Space – 200MB
Graphics Card – 800x600 16-bit color Operating System – Windows 98, 2000, XP or later
Web Browser – Internet Explorer Version 5.5 or later
Adobe Acrobat Reader – Version 5 or later
Required Hardware (Not Included)
As shown in the diagram below, an SAE J2534 pass-thru device is required to use the application.
Hardware validated by Mazda can be purchased separately from a third-party supplier. Validation has been done using the following J2534 pass-thru device and cables:
CarDAQ2534 (includes RS232 and Ethernet cables)
Cable between CarDAQ and Vehicle – CD2534-J1962-FEPS (Sold separately / Required)
PCM Reprogramming Process Overview
1. Purchase a subscription to PCM Reprogramming on this website.
2. Download the application and install it on your PC.
3. Connect the J2534 pass-thru device to the PC and the vehicle, and power it up.
4. Run the application installed on your PC.
5. The application will determine whether or not a new calibration file is available.
6. If you choose to use the new file, the module will be reprogrammed.
7. If PATS functionality is required, it can be chosen from the toolbox.
What's interesting is step 5 and 6. It's looking for a new calibration file on the internet. Now if someone somehow has knowledge how this calibration file is created or what it is, then could it be possible to use that user created file instead of one from Mazda? (ie, after market companies who wants to re-program the ECU/PCM).
Is this something new or am I just slow to catch up with things?
