Not sure if this is a relevant issue, but from what I see and hear in the above video the engine's chuff rate strangely appears to be 1 single chuff per 2 wheel revolutions (not the opposite typical default setting of 2 chuffs per rev or at least the option of 1 to 6 or 8 chuffs per rev option within the engine's DCS chuff rate settings.
It's a little tough to see from the video (angle, distance and slight shake) but when you slow the video playback to half speed it is easier to see the timing of the chuff to the wheel position.
