Have you made any runs with it hooked up yet? If so what kind of AF #'s are you seeing ? I've used my Innovate a few times and seem to be running rich (11.8 - 12.2). Have been told it should be 12.5 - 13.0. I'm running a 496, don't know if it would be the same for a 502.
Have you recorded any data logs yet? I have a heck of a time getting logs recorded and then being able to retrieve them. Some times it works sometimes it doesn't.

I have a 489 Stroker 500 HP. I run mine 13.5 at idle to midrange, then 13.0 for about 1500 RPM, 12.5 from about 4000 up. I have a thread here search for "Wideband O2 Upgrade", good info there.
