It`s been a long time , but if I remember the early AAR`s superseded to the later ones. The heater coil resistance was the only thing changed.
The later ones had more resistance across the coil or vise-versa.

So the only thing that would change would be the closings time of the little door to a different time so idle down time would be the only deferents.

I do not see a problem using one or the other as it just regulates air for high idle when cold and the deferents in time to close is not that different.

I think it had to do with the cat converter getting hot sooner or something like that.
