I am trying to specify a pnp system for my 1989 Porsche 964 Carrera 4

55pin Motronic

3.6

6 cylinder

Twin spark

Twin distributor

Twin coil (not coilpack or cop)

VR crank trigger on flywheel(?)

Hall sensor in distributor(?)

Standard ~230cc high impedance injectors

Cylinder head temperature sensor

Standard AFM (Flap style, includes AIT)

Standard idle and wot switch (no analog TPS)

PLAN

I will remove AFM and add a separate MAT.

I will keep the twin coils and distributors

I will fit an analog TPS
