SDS EM-1

[Bruce Crawford]

Someone wrote regarding the SDS Em-1D:

I have a EM-1 on a 6PI ported 13B rotary and it is darned difficult 
to get just right, but where it's right, it runs darned well. 

Perhaps the trouble is due to mixing a rotary with a speed/density 
EFI, but I can say that the EM-1 is very easy to program. Other 
oddities are the somewhat cheesy injector plugs and other harness 
items, but all in all, not a bad system for the dollar.

My 13B is running four 440cc/min ND injectors on a modified late 
model 13B intake manifold/throttlebody. The injectors are batch fired 
rather than stage fired like the OE system, and the 6PI linkage and 
rotary valves have been removed and the manifold ported.

I hear now that SDS had the EM-2 out, but I have no idea what changes 
were made to aquire the upgrade denomination.
