Sounds like what I proposed awhile back? Looks like two of us are guessing along the same lines. But still be sure. Who really knows the answer? Wish I had a single pot dizzy to experiment with.
My previous post: "Here's my theory on how the singe pot may work: Perhaps the port is actually vacuum advance at idle. As the vacuum signal gets progressively weaker with the throttle opening, all the initial advance falls off leaving you with just what's left of the mechanical. Then, as the boost builds, the pot is moved in the opposite direction and begins to retard things to a safe zone on boost".
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
