AEM EMS V2 - what table to adjust for driveability during warm up

During warm up (below 145ish degrees), when the throttle is touched even slightly the car goes to pig rich (10.0 or lower) and sputters/stumbles. Once it gets above that temp, it's fine. Can someone direct me what table to adjust to help fix this?

I'm comfortable in the AEM software as I worked on cold start a bunch in winter.

If it's important - 2150's, e85, -6/-8, etc etc, 2.3.

Thanks!

The Accel vs Coolant Temp table under the Accel tab is what gives you the ability to add additional fuel based on coolant temp.

Thanks, Master!

So do I just remove fuel from the area circled until it leans out a bit?

I'm guessing this affects e85 and 93 options at the same time? I didn't see a "Flex Accel" table.

Thanks again!

Yeah, just start removing a little bit at a time until it starts to lean out and you're happy with how it accelerates. It will probably take some time to get it just right since it's during a limited warm up window. I don't have any experience tuning Flex Fuel. However, the "Flex Accel vs Coolant Temp" table is directly under the "Accel vs Coolant Temp" table.

Granted there are a lot of variables between calibrations, but here's what my table looks like. 2.3 stroker, ID1300 injectors, and 93 octane. I will say I never spent a lot of time tuning this table because I usually wait until the car is fully warmed up before driving.
