Ignition Coil Drive Circuit

[Mark Eidson]

Text item: 

I found that ignition is critical to EFI tuning.  It is probably best to 
do one at a time using a proven good ignition system and timing while 
setting up the EFI and then once the EFI is running well look at doing 
the ignition changes or control from the EFI unit.  me

I was thinking of something similar, but decided that I would try to focus
on finishing off the EFI system first. A good place to start for 12V to
What ever supplies are in some of the mid priced Auto audio amps that has a
nice PWM supply, they put out a bunch of power, and have a nice case. I
have seen some pretty small ones in a magazine, that did something like 58
volts at 8 amps. It was not very large and looked prety simple.
