I recently drove our company's 2008 Chevrolet Tahoe from Butler, Indiana to Pittsburgh, PA.
This Tahoe is powered by a 5.3L V8, model LY5, that was was equipped with Active Fuel Management.
I did not even know what Active Fuel Management was until while driving up the Interstate, the Information Center indicated V4 Mode.
I thought it was some sorta of Variable Valve Timing, but I was wrong.
I looked it up later and as I understand it, the computer shuts of the coil and the injector to 4 cylinders.
Anyways, that Tahoe received economy numbers in the low 20's.
I was greatly surprised that a truck so big and heavy could achieve better than 20 miles per gallon of gas.
I was also shocked at how well this Tahoe drove and rode.
That 5.3 in V8 mode has about 320 horsepower and really had the zip to get up the road! I liked the Vroom Vroom!
OKAY...so you fellows that have performed LS swaps in a FSJ, here is my question to you:
With an 5.3L LY5 with its 4L60E and transfercase (NP241?) can a person get the Active Fuel Management to work in a non GM vehicle?
While doing research, I discovered that on the www.gmfullsize.com
forum, folks either love it or hate it.
Well, I can tell you that it worked well for me and I loved it.
I had the power when I wanted and had the economy when I was just cruising.
Seemed to be one of those examples of getting to keep my cake and eating it too!
My hope is that this question will draw a lot of technical discussion.
