Ok so i believe my 2009 G8 GT has the DOD?? how do you know when it is active? does the car act differently? I do notice a kind of pulsing/vibration when driving on the hwy at light throttle and if i give the car more throttle it goes away cus the car 'wakes up" and takes off...

what are your experiences?

Thats it right there..You can go into engineering mode and it will show you when it's active.

Dod can be great. But it also sucks and makes the car sluggish. Normal during city driving it constantly goes in and out of 4cylinder mode. It geta annoying

If you have any kind of exhaust mod, you can hear it clunk on and off pretty easily. You will drive around town, go to accelerate and cant, then boom you will. that was AFM turning off

Highway driving 75 mph, DRONE. Never stopped.
Coolest mod to the car so far has been AFM disabled. I woulda payed a tuner money just to do that alone lol.

You can hear it if you listen closely and it makes the car feel quite sleepy. I traded my GT for a GXP and not having it is one of the best things about the GXP. The GXP averages the same fuel usage overall as my GT too, no benefit for consumption as far as I could tell.

from what I have read if you shift over into sport mode it deactivates the DOD. Haven't tried this yet to be 100% sure but could easily be checked.

has to be manual mode, sport will still let AFM turn on.

does dod activate on the g8 in any gear? on the mcss with the ls4 it wont kick on unless its in 4th gear.

It does kick in in any car, usually when your off the throttle. It's a pretty useless design really. On my personal car we took it off an didn't notice any real change in mpg. It's more gimicky then anything. Think about it, it only goes into 4 cylinder mode when your off the throttle or slowly cruising on the highway. You can ditch it with a tuner or do it the right way and put a cam in there.

Driving my wife's GT, I'd say you can feel it if you're paying attention when cruising down the highway, but it's not dramatic or anything. A feeling of sluggishness that disappears immediately when you give it some throttle.
