Engine jerk under 1500 rpm when tuned

Hi,

I use ktuner basetunes but I've detected that if I try to accel in 2nd gear under 1500 RPM the engine jerks even if i give it just 2% throttle. I usually try to avoid low rpm but sometimes it forces me to slow down and shift in to 1st gear. Does this only happens to me? This does not happen with stock tune.

If that starts to happen, press your cruise button. It will go away. Same thing happens to me. It is slight annoyance for me when in traffic. I think it is normal unless your problem is a lot more dramatic than I am thinking.

This is because rev-hang is disabled. It always happens to me in traffic. I believe it has to do with the turbo spooling, low RPMs and letting off the gas.

To correct this; Press the cruise button (which re-enables rev hang) and leave it on during slow traffic conditions. This will stop the car from jerking in 1st-2nd gear at low speeds/RPMs. When traffic clears up, turn the cruise button off to go back to disabled rev-hang.
