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
2 knock sensors
Narrow band O2 is fitted to most models, but this car had a factory option selected to remove this
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
