I've got AC idle up worked out, the only oddity is when I turn on the headlights the idle dips about 100rpm. Wondering if this would influence performance under WOT?
Would this update address that issue? (were I to upgrade unit)

Bumping old post because its relevant to me, since the mazda 3 2 wire alternator seems to be electrically identical to the NB one. The MS3P manual says using a spark output is ok for the miata. That is correct and supersedes the info in this thread right? Also does it connect to the P or D wire? Manual says P and D sounds like it stands for Diagnostic but reading the FSM it makes it seem like D is the one connected to the power transistor and its the line you're supposed to scope to make sure the factory ECU is working right. Looking at how the alternator is wired I guess it can't hurt to try it either way till it works. Annoying that the mazda wiring diagram that shows you which wire does what doesnt show which connector pin it is and the one that says P and D on the connector doesnt show wire colors or what it does.
