EGR spark advance correction...

[marc_w]

LQ9 6.0, 2004 Silverado SS.

I started poking around with my timing. I noticed a rather large "hole" in my HO timing table. As seen here.

Today I noticed the EGR spark advance correction table, looking like it's adding timing in the area of the hole in the HO timing table. EGR spark table.

I do not have EGR in the truck. Never came with it from the factory. Therefore EGR is disabled under the "General" tab, with the bone-stock .bin.

Is this table there to add timing in for my lack of EGR?

Would there be any reason why I can't just overlay these values on top of my standard HO and LO timing tables, and zero out this table?

Just trying to keep it simple.

Thanks.
