Cant fault that there are better versions But MSD #83647 takes you out of the realm of general fit it and forget modules

that's a proper custom job....

$20 vs $190

is the extra $170 worth it for a module that in essence can run to a higher rpm. Its gonna depend on your needs i suppose

higher current shorter rise time more flexibility in RPM range provided you have a coil that is perfectly matched to the module so it can control dwell properly at low RPM.

my pot-shot was aimed really at the flame thrower and accel labelled versions of the standard modules. can't find anything to prove that they are not just modules out of the same factories as the rest with nice labels on.
Those labels and a nice box is therefore costing $25-30

I doubt there is much difference on a motor that stays south of 6500 rpm

Same motorola chip in all apart from maybe the MSD one
