Here's an old website of mine with some documentation I put together on the system as well as other electronics info:

This will get you started. I've also got two versions of the manual for the MAFT Pro mirrored on there; You may find a newer version on the FullThrottleTech.com forum as well as firmware updates. For running MAF I don't know of any significant updates worth worrying about right away, so probably best not to screw with it right now.
