Hmm.. My '96 Z28 has:

1... 180 tooth wheel on the camshaft (called hi-res signal in manual).
2... 4 tooth wheel on camshaft (called Lo-res signal).
3... 4 tooth wheel on crankshaft (CPS).

Does Ford still use 58 toothed sensors or have they increased like GM,
and why would anyone need 180 teeth in the first place?
