Can you explain why you use the factory ECM?
I'm at a point in my build where I'm looking at this and I'm torn on what to do after seeing all the success you've had running factory ECM's. I was looking in to a Holley Dominator for my LS7 because I needed DBW control and wanted to keep 2 O2 sensors, which you can only run 1 with the Terminator. I think the Dominator would be overkill really for my setup with endless inputs and outputs that I'll never really use. I just think if it works for you, it must work for me.
Would just like your insight.
Thanks,
John

I have been a fan of the GM controllers for most of my recent build for a few reasons. Refinement of calibration, and familiarity. The E67 used by the LS9 was used for a long time and was a very refined package. We have refined the 427 LS9 package for 10 years and over 30 engines. That package is sorted!
If the engine stays relatively stock the OE controllers work great with tools like HP Tuners. My buddy Dave Mikels tuned all this packages and continues to make them better.
I'm moving toward a hybrid set up on my LT5 do to the fact the GM ECMs will not do what I want to do. The aftermarket has made big gains in the last few years in refinement. I know as I move into a new control system we will have some learning curve. As a GM engineer I like things refined. Holes in an engine calibration bug me.
