same thing was reported in the Seattle Times a couple of days ago

Boeing recently discovered that the simulators could not accurately replicate the difficult conditions created by a malfunctioning anti-stall system, which played a role in both disasters. The simulators did not reflect the immense force that it would take for pilots to regain control of the aircraft once the system activated on a plane traveling at a high speed.

On Ethiopian Airlines Flight 302, the pilots tried to follow Boeing’s instructions and manually adjust or trim the horizontal tail — called the stabilizer — using a large mechanical wheel beside the pilot seat. However the heavy forces on the tail made it impossible to move the wheel. It’s this condition the flight simulators failed to reproduce.

In a statement, an Federal Aviation Administration (FAA) spokesman said the safety agency “is aware that Boeing Co. is working with the manufacturers of Boeing 737 MAX flight simulators to adjust the fidelity of the stabilizer trim wheel.”

The FAA statement added that it “will review any proposed adjustments as part of its ongoing oversight of the company’s efforts to address safety concerns.”
