Why not V4 at ECO mode all the time?
To be honest, I feel the stock settings of modes (for automatic trans) are way too conservative, to name a few:
1. Since I already switched to ECO, I won't really need so much power anyway, why not put in V4 all the time, instead switching back and force, which creates more complexity, and makes ECO not much difference from Tour in terms of everything including , maybe a bit more lag in throttle
2.Why would I ever want v4 in sports, even track mode?
3.Throttle response in sports and track can be more aggresive.
I've suggested this to the wot-tuning I purchased, and they told me that as long as I can pay for the elite package , I can probably get these tweaked.

Gotcha. I have a '14 with auto trans. In over 8,000 miles it's never seen Eco mode. Why? Because in Sport or Track mode with the trans in Manual mode using the paddle shifters it won't go into Eco mode - which is just fine with me.

"Active Fuel Management®
This system allows the engine to
operate on either all or half of its
cylinders, depending on the driving
conditions. With a manual
transmission, the system is only
active in Eco mode. With an
automatic transmission, the system
is available in all modes, but is more
aggressive in Eco mode. See Driver
Mode Control on page 9-39.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the
vehicle to achieve better fuel
economy. When greater power
demands are required, such as
accelerating from a stop, passing,
or merging onto a freeway, the
system will maintain full-cylinder
operation"
And I asked my friend who owns 2016, V4 still persist in all modes.

Maybe you are the one who should read the manual.

you are referring to "v4"
And yes, it won't go v4 because you are using paddle shift.And when you are using paddle shift, doesn't matter you are at which mode ( doesn't have to be Sports/track), it won't go v4

Why would I ever want V4 mode?

One reason: CAFE fleet average
Chevy probably need to do whatever it can to meet the CAFE fleet average.
I wouldn't mind if they stuffed an 20hp single cylinder engine in the trunk for ECO mode, as long as I can take it out immediately after delivery.

As I said in the post. It's not that I want v4 or v8, it's that I don't want a mix of v4 + v8 which i can't control. I would like to choose v8 or v4 whenever i want.
Why would i need v4 in sports or track mode? Why would i need v8 in ECO mode.
For those who never want v4, simple, just don't switch to ECO. Wouldn't that be easier? I understand the point of meeting CAFE fleet average though but I thought having a pure v4 mode would simply make things easier for GM

Actually I too have been thinking it would be a good option to be able to lock it in V4 mode for long highway cruising. I have a manual and unlike autos sometimes the transition between 8 and 4 mode isn't very smoothe. Especially when going over several gentle rises and the engine shifts modes often. At times it really feels like the engine stumbles. I drive 30 miles each way on the Interstate daily to and from work and the constant switching and occasional stumble are so annoying I just keep in Sport mode.
But if I could just keep in V4 mode just for cruising on the Interstate then I would use it.
