Yes; It may be that mine is just an earlier version. 

At least that clears up some of my confusion in regard to this relay you kept mentioning. 

As you may have noticed from my other post, I can go half way and connect the primary injectors to the secondary plug.  No joy.  The rough running could still be a “leaking” injector since it gets too rich and rough, but these injectors only have a few hours on them since cleaning and testing by RC Engineering, and their flows matched almost exactly.  I haven’t heard of leaking as a likely failure mode.

 Unfortunately, I have to agree.  "Bad injector" is an easy answer, but I haven't personally seen one yet. 

Did you already send your EC-2 back to Tracy to have it checked?  I can't recall.  Whatever you do, keep it away from John if you know what's good for you :-)
