The DCT bog - what it is and how to work around it.
The DCT in the Talon and Pioneer has a quirk, if driven up to a vertical obstacle it may stall and refuse to climb over it. Why - Our engines idle at ~1500 rpm and the clutch engages at ~1800 rpm, there just isn't any torque down there, it's a law of physics.
PaulF explains how to mitigate the 'problem' -
I have 30" tires and here is what I have discovered.
If I pull up right against a vertical obstacle and "ease" into the throttle, the machine won't move. RPM goes to about 1800 and powers out. However, if I pull right against a vertical obstacle and "stab" the throttle quickly to about 1/2 throttle, the RPM jumps a little before the clutch engages. As soon as I start to climb the obstacle, I feather the throttle back slightly and I go right up nice and easy.
At first it was a little herky jerky but with some practice I have gotten real good at it. It even works with Hill Assist.
My theory is the RPM jumps quicker when you stab the throttle and the PCM doesn't react (or possibly programmed not to react) that fast and so the stall speed is raised slightly. My estimate (by the sound of the engine) is around 2200 to 2400 RPM putting the engine in a better part of the power band.
