It works on our 06 Knight - UPShifts at 2000 RPM instead of 2200 and delays uphill downshift til you slow ~10MPH


Now THATS strange. I went back there thinking that maybe the Knight said something else. But it says the same thing as the Dip. That it is not enabled. Very strange.

Easy to VERIFY whether economy mode is available.

Accelerate at WOT (wide open throttle) in regular and again in economy mode.

Note max RPM in each gear before it up-shifts.

If no difference, no economy mode.

In regular mode, my engine up-shifts at 2400 RPM. In economy mode, it up-shifts at 2000 RPM.

There will be and should be NO DIFFERENCE in shifts at part throttle, ONLY at high throttle settings.

In reality the economy mode does very little to effect the economy of operating your motorhome, unless you are doing lots of city or mountain driving. It has "zero" effect on interstates and alike. So don't think you might be or could have saved lots of fuel.

Actually it is in rolling hills where economy mode gives the greatest increase in MPG.

In regular mode, cruise control or maintaining steady speed with accelerator: Starting at bottom of hill going up next one (NOT mountains, just rolling hills)

Throttle goes to WOT in 6th gear, downshifts to 5th at WOT. Top of hill, shifts back to 6th and then throttle closes (or worse, throw on exhaust brake which downshifts transmission and prevents building a little speed to "attack" the next upgrade (again, we are talking about rolling hills where building 3-5 MPH more speed is safe). At bottom of hill, back to WOT. This repeated 6-5-6-5-6-5 uses a lot more fuel than having the transmission stay in 6th gear (economy mode).
