WHY?? Have you driven a C7 auto? The change from 4 to 8 is seamless. The 8 is there before you think you need it!!I didn't buy a Corvette to save gas mileage, is there a way to enable all 8 cylinders on an automatic LT1 fulltime?
not correct...the afm is on all the time in every mode in an A6 (noone knows abouot the a8 yet)...you must be in MANUAL to kil AFM with an A6...Sport mode will let you go 8 all the time. But WHY?? Have you driven A C7 auto in Tour mode? The change from 4 to 8 is seamless. The 8 is there before you think you need it!!
Thank you. Stand corrected. For a moment I got it confused with NPP. I am going to modify my post.not correct...the afm is on all the time in every mode in an A6 (noone knows abouot the a8 yet)...you must be in MANUAL to kil AFM with an A6...

I believe it's Always the same 4 and the wear issue has been beaten to death but no one really knows how the new generation motors will hold up.When in four cylinder mode, does it vary the all cylinders equally for even wear, or does it always fire the same four?

They did give us an on/off with the 7 speed - ECO Mode.I love the car but this is the only thing I wish they had made as an on/off switch.
I have AFM (AKA DoD) disabled on my Z51 with NPP and A6. The Diablo tuner will allow you to modify and disable it if you wish. I didn't like the car going silent whenever I got over 25 MPH.I didn't buy a Corvette to save gas mileage, is there a way to enable all 8 cylinders on an automatic LT1 fulltime?
My observation from things I've read on this, and other, forums is that there seems to be a correlation between the AFM feature and certain problems (e.g. torque tube rattle, belt tensioner). Therefore, I don't use it. I still manage to get 26-27 mpg on the highway in 6th gear. Good enough for me.I had an '89 Vette way back when and I loved the rumble of the engine and exhaust. I have another 4 cylinder in my garage if I want to save on gas.

The G8 crowd experience lifter failures with the AFM lifters. They were supposedly updated at one point but not sure if they were truly improved. With LT1 being a new animal, it's possible that GM learned from the G8 failures and has improved things by now. Let's hope at least. If the lifters are of concern, you can always remove the hardware and install more aggressive cam while doing so.

When you say seamless, does that mean you do not notice when the car shifts in and out of 4 cylinder mode? If so, there must be something wrong with my vehicle.Feels pretty seamless to me. Never thought about any additional wear though...

Take it in...the AFM is not noticeable at all to 98 pct of those that own it.....When you say seamless, does that mean you do not notice when the car shifts in and out of 4 cylinder mode? If so, there must be something wrong with my vehicle.
The car loses so much power it's hard to climb a hill until I give it gas and it goes back into 8 cylinders. It's been that way since I first bought it.
I have an automatic LT1
