Thanks for the comments fellows.

I will check out the Buick site. Good suggestion as all of these forums contain a lot of valuable info.

My plan is a 427, stroked Dart block. I’m assuming the VE parameters for this engine would be so different that the EEC-IV will not work well and even if I use the TwCeer (Sp?), I will be limited in my control of the engine parameters. My understanding of the TwCeer and SDS systems is they are simple and work well, but you are limited in what parameters you can change, features like logging are limited, and base program support is not included.

I probably didn’t explain myself well
. I may have led you to believe I wouldn’t tune the engine by dyno, but that's the plan. I was trying to determine the value of wideband O2. Does wideband O2 allow for better closed loop operation over normal O2 sensors? Is the real value of wideband O2 sensors their ability to facilitate tuning?
