Jack,

sorry yes I mean beetle.
this means 8000rpm/60 =3D133hz/2 =3D 66.6 this is what I should see per cyl=
inder=20
right?
and by looking at main sensor side (or coil side) I should see 66.6*4=3D266=
..4hz=20
now I am totally lost... are you sure it divided by 2?

thanks

AA

Hi Andre -

"VW Battle engine"  =3D "VW Beetle engine?"...

If it's a 4-cycle engine, and the rotor you refer to
is the distributor rotor, it turns at 1/2 crank speed.
