DIS for GMECM

[mta228]

I am a bit confused on this one.  Why would you need a little box to set
between the ECM and the DIS ignition module / coil pack?
    I thought it was simply a matter of wiring the EST, BY-PASS, and
Reference supplied for the old HEI distributor system into the corresponding
terminals on the DIS ignition module.  Does the ECM somhow know that the
ignition module has determined its reference pulse from a crank sensor
rather than a pick-up coil in a distributor?

Maybe a stretch for GMECM, but I found out about a new product from
Electromotive that allows you
to use the LS1 coils with a crank trigger of your choice w/ECM timing.  It
comes with a little
harness and a box that is about 2x3x1 inches and it accepts ECM timing
controls.  I do not know if
it allows for individual cylinder timings, but I know that for my aujp it
won't :)

I saw this on a 454 engine at the PRI show at Indy this weekend.  The
interesting part was that
the valve covers and coils were 454 factory parts....
