[Gmecm] memcal report

[Dave Williams]

  I'm running a Lumina DIS memcal (stock) with a 2.5 TBI Chevy four, 
with distributor.  Various people have claimed the DIS and distributor 
code have differences in dwell timing, among other things, but it 
starts, runs, and I've driven it around the neighborhood.  I don't have 
plates on the truck, so I haven't driven it any further.

  The other day, as an experiment, I plugged in a memcal for a 2.0 OHC 
port injection DIS motor.  The 2.5 started and ran.  I didn't drive it, 
and I have no idea what horrible mismatches there might have been with 
the gazintas and gazoutas, but it started and idled just like the Lumina 
memcal.

  I then tried a Turbo Sunbird memcal.  The 2.5 started and idled with 
that one, too.


  This indicates to me that the resistor networks are all pretty 
similar, at least enough for the engine to start and run.  It was 
interesting that TBI/PFI and DIS/dist didn't seem to make any difference.
