Well I'm running it so I can answer any questions you have about it.

Works perfect with the stock ECU. I actually have the stock ECU controlling the IAC motor... stock ECU controls the idle airflow. And with the MEgasquirt is idles BETTER than with the stock ECU controlling the injectors. I get a rock solid 800 rpm idle once warmed up.

I have CEL. But I had it before because of my evap and egr being out of the picture. I havent pulled the codes since I had the Megasquirt running. I will this week and see what we got. Probably codes for injectors. That's all I would expect. Because I have nothering hooked up to the stock ECU as far as injectors go. But if need be a resistor pack will fool the ECU.
