You need to find out what you have, and where your going.  Sensors can get
into a bunch of money and not all ignition componemts are
plug+play.  Are they relecurtor/coil, or hall effect.  TPI?.  Number
cylinders, year of engine.  Two seperate dissies might leave you needing two
ecms to run the show.  If that's the case I'd be sure they can be run open
loop.  Then look for a ecm that supports what you want.  Turbos, etc.   See
if there is a cheap backup available, and what the warranty is.  One thing
I'm considering doing is playing with a delco, and haltech box since they
both use about the same plug ins.  That way I got me a spare to drive home
on if the $$ unit fails..
I'd kinda like to hear how ya go on all this!.
