[Diy_efi] RE:Ignition amplifier Bosch 0-227-100-200

[Mike]

I'm doing an uprated RB30 ignition module and toyed
with doing a dwell adjust, worked out an easy way to
do it along with auto retard for turbo boost, but decided to
keep it simple so first one will go out on market only
as upgrade with a couple of diagnostic functions. The old
unit by Nissan/Hitachi looks like a transistor but is an
IC in a To-3 can with back emf control but loses 1.5 to 2v
saturation plus it has a slightly variable response time.
Depending on how things go I might add a timer-control
chip to provide some dwell adjust for ECUs that dont offer it,
mine at present does its the Skyline/RB30 ECU with Bosch/Hitachi
innards...
