Probably will add one on my 2016 Yukon with 91K miles and was considering the Range Technology, but then a friend said he got one off Amazon for around $100 for his Tahoe years ago and has been working fine.

So my question will be is there a reason to pay the Range Technology price or are others just as good?

Nobody that's experienced success or failure with another AFM disabler here?

I am watching but I don't have any knowledge of this but I say give this some more time. A lot of good folks on here and some answer only on the weekends - and you asked your question on late Sunday night. This is a popular topic so I'm sure some will chime in. Plus, there are plenty of previous discussions very similar to this. Not sure if you searched that already.

I would add, do pretty quick. 90k miles is right in the danger zone for engine and transmission failures due to that cylinder confusion deal.

I have a Range listed in the classified section for a lot less than what Range is asking, just check their site to see if it is applicable to your vehicle.

I ran a RANGE device from 42k to about 155k before I bought HP Tuners and shut it off. It worked just fine for me. It's for sale if you're interested. I don't have a need for it anymore

range probably has the best reputation for AFM disable besides an actual AFM delete via tune.

Sometimes you get a good deal, and other times you get what you pay for. ask yourself this question — are you willing to gamble or go with the tried and true ? Not saying the generic wouldn’t perform, just food for thought.

Imo, I pick and choose where to spare expenses and where to go all out. Until I could do an actual AFM delete via tune, I’d run the range but that’s my 2 cent$

members here may give you a good deal on a used unit. Good luck

I have a question for Range users. I only drive about once a week. Should I leave the range device unplugged until I'm ready to drive? or does that confuse the ECU?

Thanks in advance

DISABLE
via tune.
Disable = making it impossible for the feature to activate, but leaving the physical hardware alone.
Delete = physically removing the feature's problematic hardware.
Yes, a delete requires disablement.

Unless you suspect that you are under surveillance, leave it in -
at least until one week before your emissions test.
Give your readiness monitors time to prepare.
(Along those same lines, keep your gas tank as close to 1/2 as possible, and do MORE short trips.)

I'll sell you my Range for $100 if you want it. It's literally just sitting in a drawer on my work bench. I no longer have a vehicle with AFM. I had it on my 2016 Silverado for about a year.

OK ... yes, you are 100% correct. a tune would still only disable AFM, you would still need to change out some pieces for an actual AFM delete. But the point I was making still stands: AFM DELETE would be the best option, but if for whatever reason you can’t or don’t want to .. Range is probably the next best option.

I was not disagreeing with that point.
Just saying, dogs aren't wolves, although they're clearly related.

I'm HOPEFUL that more people come to understand that
(at least) disabling cylinder deactivation, whether by plug-in or tune,
will make your GMT900 or younger vehicle more valuable come resale time.

I know that I am not alone in preferring a vehicle whose cylinder confusion has been disabled most of its life
compared to someone who brags about fuel economy because they could not be bothered to disable it.

Properly deleting cylinder confusion costs thousands.
If the previous owner did not even bother to disable it, they are passing that buck to the next owner.

My Yukon is pretty much a weekend warrior. I left the range in all the time without issues.

Only time you have to remove it is a few days before emissions inspections. For some reason, if you unplug it right before inspection, some of your monitors won’t be ready and you’ll fail.

If you’re not in an emissions state then this doesn’t have any affect on you.

How do I find the classified section?
