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

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:

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
