Not sure exactly what would be right, but for SOI Cat Lightoff I make the table more similar to base SOI. EOI Split Cat Lightoff, I also make more similar to EOI Split base (150).
Of course there is more fuel smell than a catted rig but these changes made a positive difference on catless L86 race trucks.
I went ahead and made the suggested changes to your file but the uploader is acting strangely. I'll upload it pretty soon and you can compare it with yours to see what you think.
I finally got the file to upload. Must be the browser on my other tuning laptop. Please let me know if this helps your fuel smell.
