Note that the intent of that rule is not that you have to use its signal, it's to keep you from modifying its mechanical "operation" -- and thus air restriction. Other regs allow you to install a MAP (if not already equipped) to properly work with the Megasquirt.

We've debated this back and forth, but no one has yet to come up with a good verbiage to replace that, without allowing some level of intorturation of the MAF.
