Not sure what you are asking, but I know on the full size Silverado trucks, they sell Tuners that have the option of deleting Cylinder Deactivation, not sure if they have them for the Colorado/Canyon trucks.
Let me guess, your truck is new and youre not seeing the AFM operate as often as you want?
This is a issue that will improve with time and miles. Mine works a lot more that it did in the first 20K.
And quit watching for it. A watched pot never boils.
why would anybody want to extend the v4 mode, that just makes the engine work harder???? I have the afm disabler!! No difference in mpgs for me, and with no premature engine failure from that stupid afm system!!
I did see a noticeable improvement fuel economy (basically on highway driving) on my G8 GT when I finally got the tune the way I wanted it. Took plenty of trial drives, and a couple misadventures (one time I was much too aggressive with the settings and had it in V4 mode only, that really sucked), but eventually I was able to find a tune which improved mileage without much change in driveability.
Things like AFM. Auto Stop and the shutters on our trucks earn what is called Off Cycle Emissions Credits. Much of this is done for emission credits not MPG.
The EPA awards credits to MFGs for these things that can not be tested easily. MFG eat them up. The true results of staying in 4 cylinder mode may not net the effects you really want as it is more about emissions.
Here is a story on the start stop systems but it also details how the EPA applies the Off Cycle credits here.

Last month I purchased a new 2018 ZR2 V6 with the new 8 speed tranny. Awesome truck! Yesterday I was toggling through my gauges and came across my transmission fluid temperature gauge. I was surprised how cold my transmissions was running (around 95 degrees Fahrenheit [the engine was up to temp...
