LH 3.1 I imagine. This is because, supposedly, the hot film (as opposed to hot-wire as in previous LH incarinations) AMM doesn't react very quickly.. so the TPS is used for acceleration enrichment (sorta like the way that a K-Jet air flow meter overswings briefly when you accelerate).

I really have no idea if this is why the TPS on the later cars is a potentiometer or not.. the only reference I've seen to that was a brickboard post. Maybe someone more up to date on Bosch FI can comment (the only reference I have barely covers LH 2.4).
