What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I jokingly HATE all of you with the lower than 2.00 a gallon. 2.40-2.89 locally,

Can I still be your friend? Gas is $2.02 by me.

Sounds like you're in good shape. Unless you wanna keep AFM operational in case you ever wanna turn it back on (I don't know why one would ever want to do this), there's no need to re-enable it, especially if you're gonna delete it one day.

So my understanding is if you want to delete AFM, you have to either get/borrow/or have the dealer shut it off with a Tech2.

OR

Purchase a something like HP tuners to delete it.

OR

Send out the BCM to have it done.

Mine is driving me nucking futs at slow surface street speeds. I’m lucky if it kicks in on the highway with all the other brainless dickless spotty headed morons on the road and the way this highway sucks for setting cruise control on.

Dealer won’t do it.
Range device Diablo or black bear
Ecm
Drive around in m5 if 6 speed.
Use tow haul mode( shuts it off)

I tried running in Tow/Haul mode when we drove to Texas last month and swear the DIC showed my 2013 switched between V4 and V8. Will have to get out and try it again to see if I am nuts or if it really did switch.

Ya know I haven’t tried it in awhile but I could swear mine wouldn’t switch when I first bought it with towhaul on....I disabled afm very early on so now I don’t remember..... I guess if you remember next time you’re out in yours check it and report back

Dealer won't do it and I don't think a Tech2 can do this, anyway.

You could get an all-out tuning program such as HPT or EFI Live, but that's not necessary unless you wanna learn how to tune.

Not the BCM, the PCM. THis would be the cheapest option as there's a guy that does it for around $50, IIRC.

Just to disable it without an actual tune, you could buy a handheld tuner or Range device. Years ago, I had a speed shop turn mine off as well as the rear O2 sensors. Also had them remove the speed limiter, reduce Torque Management a hair and slightly raise the trans line pressure for $150. I agree that there are very few instances where all the stars align for AFM to be engaged long enough to be of any benefit. Even then, what little benefit you may gain from years of using it are more than negated by the expense of repairing or deleting it when it acts up.

This is exactly what BB did for me, except they charged $350. At least I have lifetime retunes if I need them.
