Right now there's a chance you're sending a little extra fuel out the tailpipe when you step harder on the throttle (from what I can find on Google images, your engine seems to activate open loop enrichment at low speeds). If you get a flash you could get rid of that. You can also add enrichment and then use a narrowband emulator to run lean and get a 5-10% boost in fuel economy. On these bigger engines it should really help a lot.

Nope, haven't mentioned tuning previously. I know there is plenty of ECU support for K engines, haven't heard much of tuning J engines. I'll have to look it up when I have time, right now aeromods take priority because my commute is 90% highway, and I have a family road trip coming up. I used the scangauge to see when open loop occurs on my old 4 cylinder accord and it was only during warmup and above 90% load I think, have not set the loop gauge to monitor the V6 yet. I'll try it out. As for running lean...Ehh...I would rather add ignition advance before trying to run lean. I don't like the idea of increased NOx emissions either, but I would be all for removing fuel enrichment below 80% load.
