Thanks Stony for posting this.  I just finished building up my RB with an AEM EMS V2, and after trying to start, it would crank for 4-5 times and catch and start for like 1 second and then die.  Then it would be difficult to fire back up, only to catch for a sec and die again.  I have a feeling after reading this that it's 180 degrees out.  Does this sound like the same symptoms you had?  I'm going to try your switched settings and see if I can get it to fire up.
