just thought id point that out :roll:
It's not a drastic change, just a clever addition to some computer work and the spark and fuel don't go to 1/2 the cylinders. Not like their adding on 2 more doors or something like that.
I think you are dramatically under-estimating the complexity of succesfully and graciously killing 2 or more cylinders under load - and then firing them right back up like nothing happened...
its more then a drastic underestimation; its a very very different process required to perform this seemingly simple task? its so complex, im sure i dont know half of what would go into it separte from a normal motor, i could name easily 9 or 10 severely different items id hope GM, as well as the rest of the auto manufacturers shy away from this awful technology
