Disable AFM?

raress9596 · January 4, 2017

Wondering if AFM can be disabled by a GM Tech using a Tech 2 or something. (If I could get one to do it). Is it possible. Truck vibrates and growls sitting in stop and go traffic under light accelaration. I know aftermarket tuners can. TIA

Range AFM disabler IMO. Look around this site, lots of info.

Before tuning my Sierra with DiabloSport's inTune i2 and disabling DOD (AFM), I always would drive around in M5 when in city traffic. This keeps the engine out of V4 mode.

The dealer cant turn off the AFM, only way is thru customer tuning or via one of the aftermarket bypass modules. Otherwise drive around in M5.

I already have the Diablo version of the Range. Works good. Just don't like the idea of plugging it in and out if you don't drive it for a few days. Sometimes i do, sometimes not. Also wonder how long it would take beforew a pin gets bent from taking it in and out. Figured i'd be able to bribe a tech to shut it off. oh well. I have the Diablo tuner for my SRT392 Charger. Going to shut off the MDS in that too.

Why can't you leave the Diablo plugged in if you don't drive the truck for a few days? Does it drain down the battery? Wondering here because I'm thinking of getting one.

According to their instructions if it's not going to be driven for more than 24 hours it should be unplugged. It has a parasitic power draw. Otherwise it works great. I actually enjoy driving the truck now. Some people have found their batteries going dead after 3-4 days. Big drawback. Didn't know it till I got it. Probably going to get it "tuned" out down the road.

I have the Range AFM disable device. I do not leave it plugged in as most of my driving is around suburbia where speed never really gets over 50-55mph, and I use M5. When I go on longer highway trips I use it..............has worked perfectly. Was pulling 20-22mpg in V8 mode highway before the cold weather got here.

The Range kills my battery if I leave it plugged in for more than 4 days without driving.

Use this, all you have to do is switch the range off when not in use:
