I guarantee that Bill sent you PMT1 programming though.

Total? Gosh....about this many: http://www.thedieselstop.com/faq/949.../pcmcodes.php3

There are a couple more since that listing was made. However, just compare the "template" code and look at the first 5 digits, group them, and count the number of groups. In the "Downloads" portion of Powerhungry's homepage, there is an Excel spreadsheet list of all of them as well.

One definition file will cover however many PCMs have the same first 5 template digits (VRAA6, etc.).

You will get weird values on some of the definitions because they are based on specific ADDRESSING of "code" in the PCM's memory. Here's a neat scenario...it is possible to tune most any PCM with a few of the "wrong" definition files. The way the addressing of code works out between different PCMs sometimes allows you to modify correct data in a table, but the values on the x and y axis will be all over. It can also work the other way around. It's Ford's way of keeping hackers on their toes.

As far as the difference in VRAA6 and VRAA7 and the transmission strategy is concerned, there really isn't that much difference. Just nit-picky things for the most part. Comparing a PMT1 and PMT2 side by side won't show much of anything.
