Heh, well that explains it. Usually when somebody has "newb" under their name around here, you're in for a long conversation.
It fails me to set timing at the CAS procedure. Setting fixed angle to 10 is WAY slow to even fire the motor. Going to the map and tweeking to that Monstrosity got it to run.
Well, here's my usual procedure for setting the initial offset on a new engine. First, disconnect the injectors. Now, hook a timing gun up to #1. You'll probably need to power the gun externally, as we're gonna be drawing down the battery here. Put a paint mark on the notch in the crank pulley. Lock the ignition timing at 10, lock the cranking timing at 10, and have crank over the starter while you watch for the mark. Adjust as needed.
If it was running on the stock ECU before, then you should be pretty close. You've got a pretty wide latitude for adjustment in software, though it does have to be within reason.
Can get it running and keep it running with the ignition locked at 10, at any RPM? That will make this far easier.
A few thoughts...
Is it possible that the mark on your pulley isn't where it should be? I've never seen it myself, but some folks have experienced slippage of the crank pulley. It's a two-piece assembly with a rubber ring in the middle, and the notch is on the outer half. Pull your #1 plug and drop your oil dipstick down the hole. Turn the engine by hand, and very that the mark on the pulley actually hits "0" when the piston crosses TDC.
Maybe this isn't an ignition problem, but a fuel problem? You said you didn't have the wideband in yet, so perhaps your mixture is just totally off in the weeds?
