Extreme Economy Tune
I am just trying to promote an educated discussion here. This may have been thought of already.
I was wondering about some of the trucks now a days that shut down 2 or 4 cylinders based on load and throttle position and was wondering why something like that hasn't been done (that I am aware of) on the 6.0? It seems to me that it is something that could be done with a tune, maybe interrupt the electrical signal to the injectors.
Say your cruising down the highway or in town and you could flip a 3 position toggle to turn your 6.0L V8 into a 3.0L 4Cyl, or even a 4.5L 6Cyl. I could see it vibrating more due to the "misfire" but what if you could have it rotating through the cylinders, for instance just say it is hitting on all 8 cylinders, and if you flip to switch to "6 cylinder mode" it would interrupt the fuel to cylinders 1 and 2 for that rotation, then cylinders 3 and 4, then 5 and 6 and so on. I am sure there is a way based on firing order to interrupt the fuel in a way, that you would still have 1 cylinder firing on each stroke, instead of having 1 stroke where there is no firing. that would help to minimize the "misfire" vibration.
At least that way if for example you left it on 6Cyl mode for long periods of time, the "wear" on the engine could stay fairly even, versus shutting fuel on cylinders 1 and 3 the entire time, by having the misfire "rotate" through the firing order.
What made me think of this was the fact that one of my soldiers had a nice gmc sierra that would basically rotate between being a 4, 6, or 8 cylinder engine based on load, and the fact that on the highway without towing and cruise control set, he was breaking into the 30's for economy.
Whaddya guys think? Maybe some one more educated can "learn" me as to whether this would be good idea or not.
