AFM Disabler differences?

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.

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?

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.
