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.
not sure if this is true. i took my 16 canyon 2wd in to the dealer for a trans and diff fluid change and the service writer asked if i wanted to get the front diff serviced too. i wasnt aware there was a front diff on our 2wd trucks. he wanted $450 to do the job. i opted to not have it done, but...
Head up long post.
First off I've read alot of other posts about a/c issues, so if we could refrain from posting links to other ones that are very vague. Thanks.
I'll start by saying I've only had this truck for just over a month now. I have only ever used the a/c in the manual position with...
I recently purchased a 2020 Colorado V6, and was hoping for some input regarding potential issues. The truck only has 3000 miles on it, but since the beginning I have had the following problems:
1) After the truck has sat for an extended period of time the first few gears experience hard...
I just caught wind of a very important update to the transmission shudder TSB.
Apparently, as of July 9th, the TSB has been revised to no longer require diagnostic procedures. This is obviously big news for those of us who have had to jump through dealer hoops to get anything done.
So the manual says 5W-30, which I'm reading only comes in a synthetic blend? I'd like to use full synthetic, but I'm reading that doesn't come in 5W-30 for a true full synthetic. Should I use 5W-40 Full Syn, or 5W-30 Syn Blend? I'm in Dallas so no worries about cold temps..
What brand oil and...
