ReadMe.md

This is a work in progress.

Our goal is to be able to read and write the contents of GM Powertrain Control Modules, such as the 12200411.

Reading is working well for bhte 12200411 and possibly also for 9354896 PCMs.

Writing is working well enough on the 12200411 to try it on your project car, but you probably shouldn't try that with your daily driver until it has proven itself a little more. Writing is not yet supported for any other PCM.
