Thanks for the explanation Alex. I meant to delete that "double the voltage" thought - one of the documents mentioned that the secondary potentiometer produces "exactly" half the voltage of the primary, but that doesn't actually seem to be the case based on other documents.

MS43 might be the way to go at those prices, though the 2.8L motors would need a custom tune since there's no 2.8L M54. I assume dinan never made an M52TU throttle body? I wonder if Alpina did (though even if they did, they'd never sell it).
