The MSD, (multiple spark Discharge) helps with the lean-miss fire
Vanagons are famous for. You get multiple chances of igniting the
mixture. This helps reduce CO for the idle tests that Syncros get.
However, if the engine is running properly, I do not see too much value.

Dennis,
Any thoughts on multiple spark discharge MSD units helping the smog
numbers
on the wbx?

> Unless there is more than one "Blue" version, this coil is designed
for a
point ignition system and the coil has a built in current limiting. The
Vanagon ignition is a variable dwell design with the current control
part of
the electronics. The Blue coil will work but will deliver less spark
energy
than the proper oem coil. The oem coil has more than enough energy for
any
normal operation. The only ignition upgrade worth considering is
possibly an
MSD system. Bring money.
