Why are people so concerned about this topic. I do not understand it. Just drive it. End of story. And yes, even if you can't figure out why the truck has it, it is to save fuel.

No, it does not. Not even close. The only Cadillacs that possibly exceeded the weight of 2014 GM crew cab 1500 4x4 pickups were the old land yachts (1976 and older) models. I believe that a 1976 Ca

Whats up with the name calling?   Cant you see we agree----the AFM feels like a gear shift!   Many people want 6 and 8 speed tranny and then complain they can feel AFM. That is what I dont unders

I emailed them last week asking about what version is needed for the 2019 trucks. 

 

They said 8.6r1 is the current version.

My wife always says she can feel it going in and out....HAAHHAAH
No i'm not off topic...
I can actually feel it kick on and off in my truck with the Borla. I can even hear some flutter.
Back with the stock set up, I could not hear the difference but can still feel the difference.
On our old Honda odyssey, one could not tell or hear the difference at all.

I a 100% agree stock exhaust I couldn’t tell once I did cat back and removed the flapper I could tell. So I just bought a tuner and turned it off. My MPG actually went up lol.

Do you have a sticker stating the version #. I will have to count the blinks when I start it up, supposedly that also tells you the version.

I just got mine today and the version is on the box and I did verify with Range (ordered off their site) and it is as AtlasFBG2 said:

8.6R1

And yes on start up it blinked 8 times, paused and then blinked 6 more then went steady light in, mine is green.

Not to hijack the thread, but I will be getting a custom tune this Friday and my range (purchased 10/18) will be for sale. I have been very happy with it.

So stupid question of the day, and no I did not read all 31 pages.  2014 Silverado,  5.3 59,900 miles and automatic of course.  Will doing away with the AFM in town, help the extremely crappy 1-2 or 2-1 shift?? I swear its getting worse, dealer says, "thats just the way it is"  I am assuming I just can turn it off or on as needed?

@wmgeorge64 just drive it around in M5 and AFM won't turn on so you can see if it cleans up your shifts and how you like it. If that takes away your crappy shift then get the Range if you don't want a tune. I've been driving in M7 (have 8 speed) for awhile now and just picked up a used Range to see what the difference is in my MPG with and without being able to use that 8th gear. Worked fine for me as I usually do stop and go driving. I only use AFM when I'm taking really long trips.

It doesn't run down the battery anymore?  Is this new?

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      This is NOT impact damage nor neglect. There were previous class action lawsuits because of such paint preparation st GM manufacturing plant. Not just the Cherry Red Color. This paint is applied in three processes to obtain the desired color.  The manufacturer will cover for 36 months or 36k miles only. That rust is actually corrosion because of the paint process failure. Corrosion is covered for 100,100 miles or a certain months. However their corrosion doesn't include this type. Go figure. Clearly manufacturer knew from previous paint issues. This started 3 weeks ago out of the blue.

      Is it time to put a piece of tape over the CEL?

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL
