I don't think it does. Other sources I've read suggest the larger nacelle introduces a pitch up during certain flap configurations and at a high angle of attack. It's not the engine thrust that's the problem, but the drag due to the large and further forward nacelle. That's the justification for the MCAS software.

- ncmncm 8y agoIt's both. The engine thrust center is also farther below the center of pressure of the airframe. And it can apply a lot more thrust than the original engines. The point about lift from the engine nacelles was that it acts as positive feedback: if you are already pitched too high, it acts to worsen the problem. And, because it is farther forward, it has a greater lever arm to act.
