The TP-45 type ignition module does not control advance and
changing the module should have little effect on the timing
or ping, if the module is to spec.

Absolutely, the springs and weights as well as the vacuum
control how much and when ping. If you want less pings when
the throttle is applied you want the vacuum control to
react more quickly (the vacuum control retards the timing
as you apply throttle) an adjustable Vacuum control is
available under the ACCEl brand for HEI distributors.

Is the NAPA (TP45) or the Delco
(1875990) module any better than the
other?
