How does it work?
Any issues with warning liters, glitches etc.?
I hate to ask a dumb question, but what does AFM do on the A6?

active fuel management does the same thing on every car or transmission combo. it is just more active with the auto. becomes active more often.

I totally dislike AFM on my A6. I always drive it in M.
Range seems to be the way to go without warranty issues however their website indicates that there could be problems with their unit on the C7. I called the Range company and left a message. So far I did not get a callback.

That would be the perfect solution! But, I can't see it happening because it's part of how GM derived its "official" MPG rating.

I don't think that keeping it in "M" is a solution.

Interesting story:

A friend of a friend was thinking about a new C7 and asked if I would mind showing him my car. Mind? I was happy to show him, and take him on a long ride. He loved everything about the C7! AT one point, he asked "What happened to the exhaust sound?"... He noticed the impact of AFM on my A6 right away!

Seesm to me there should be a number of items that impact the AFM algorithm. I keep hoping that faking out a simple sensor would offer a better solution, a-la-CAGS eliminator.

There are a number of things that impact AFM activation and deactivation.....however, passenger ears are not one of them.

I bought a rangeV8 about 2 months ago, I use it on my VY Z51 A6. so far so good, it keeps it out of V4 mode completely no matter what. I haven't used it in weather or eco mode but I'd assume it'd work the same.


one thing i've heard is the device creates a bunch of network traffic within the can-bus & can be the cause of the DTC codes it throws in other cars. mine hasn't thrown a single code yet. the only negative to this device is that it'll drain the battery. not very fast but about 2-3 weeks would probably kill the battery. so you have to remember to unplug it before you get out of the car.


I like the sound a lot better since it's in v8 mode, so no exhaust valves pinching shut & no identity crisis whether it's saving fossil fuels or not. That much is very nice.

You don't mean EVERYTIME I assume, you mean when you park it for "extended periods" like say when away on vacation right?

I would agree that it should be removed for extended periods, but it should only be using 200mA at the most, so day-to-day should be just fine if you're running the stock battery.

I think you'd have a helluva' lot better chance of explaining away an "unknown accessory" plugged into the OBD port than why the ECM has been flashed.
S.
Spoke to the Range tech help today. They are still having some issues. They are working on a software mod that should eliminate all problems. Will be ready in approx a month. Till then I drive my A6 in M. Can't stand AFM

I would love the option of using AFM in Weather, Eco and Touring modes and disable it completely in SPORT/TRACK modes. Seems like a simple tweak of the software either in the car (by GM) or our aftermarket guys with their gizmo's.

I live in Illinois and most of my highway travel is on very flat roads so allowing the car to drop into V4 AFM mode is something I could use and appreciate.

Even on flat roads AFM kicks in and out every time you accelerate.
It is a simple tweak with a Tuner. However warranty issues can occur. The M7 is perfect.

Thanks for the info. As discussed there are still some issues with Range. You are in the majority with no problems. I am waiting for their latest software update coming in approximately a month.

I sent an e-mail to DiabloSport asking them about this very question. I'll let you know what they say.

Hell even GM could/should do it.

There is no reason GM should NOT have done this in the first place... who the hell wants their car running in four-cylinder mode when they're playing around??? As long as the default setting has AFM, the EPA has to accept the mileage increase it gives, as they run their tests in the default configuration. I don't know what GM's problem was there.

Hopefully, they remedy that nonsense in the A8 cars.

Not to burst your bubble, but they had answered this question recently.

They said (paraphrasing) that the confusion it would cause most people wasn't worth putting it into the options. I'll go find the exact quote.

HPT is your option for doing that at the moment, and you know what that means warranty-wise. Roll of the dice versus something like this that you can plug in and take out at will.
