Questions for those that increased 4V time

[ToddEdge]

What exactly is 4V mode?

Thanks,

Fuel management ... engine switching to 4cyl mode to save fuel.

my 2007 got 22mpg over 4 tankfuls from SC to NY (2 tanks up, 2 back)

must have been a flat area around PA or something

around town, i get ~17mpg.

but if you consider that you really only get that GREAT mpg on long trips, and AFM is caking up the carbon in the cylinders that are not running,
that bit of increase is not worth it.

Texas SPeed and other shops make kits to take out the AFM/DOD lifter and replace them with regular parts.

i did mine with hptuners, its very easy. compared to performance tunes or drag cars...AFM tuning on a suv is simple. actually the extent of tuning any of these SUV's requires a level 1 tuner at best. shift points/ tq management...all monkey level tuning

can you send me some screen shots of which tables to modify ?
