HG there is MORE VACUUM (as in inches of Mercury or HG in Latin)
the dwell is very fast, see it>
the CMP (CAS) sensor is blow, trace 2, bottom
you can see there relations ships clearly here.
CMP times it
ECU charges coil the releases it to make spark.
that huge spike seen there is not the HV side, its the back EMF spike from the primary spark coil but is same instant of spark there.
or 89/90 has none of this. this is 1991 + 8v. only here. outside usa they used this for many more years, on VITS.
