It's under the spark tab.

Catalyst warm up doesn't come up in the search, but if you search "startup" it does... Bad search engine in hpt

I set all spark modifier values to 0, but it's been really crappy weather here so I haven't had a chance to burn off the 93 in the tank to test this.

Thank you both.

What is odd is the King posted was different from my 17 SS 1LE to my 16 Sierra 6.2. The SS was set at 10° and 109° where the truck was at 63° and 109°. I went in for now and changed the SS to the same as the truck and zero'd out the main base timing table on any of the negative values.

The SS has always started up normal, trying to fix the truck. The SS runs a E85 blend since it has the Procharger, the truck run full E85 (well around E70 now that it is winter).
