Yeah, the Djet tester I have was made by EFI Associates LA.  It can 
test the 8 cyl Merc, but I don't know if my harness will fit.  Is  your 
ECU about 8" x 12" and have the 25 pin connector on the end?  If so, my 
tester should work.  What part number is the ECU?  I don't have much in 
the way of schematics, but that vintage electronics is my cup of tea.

I could check your dist, too, and dynamically test its inj. contacts.

The Djet in 4 cyl engines has just two injector circuits.  I'm 6' and 
fit the 914, but my 6' 4" son hates it.  You would need a bubble 
canopy.  :)
