IconPilot

I have the same problem. The Saitek TPM (Throttle, Prop, Mixture) controller worked fine. I just installed FSX Steam edition on a new PC. The radios and other devices did not work so I went to Saitek and installed the latest drivers. Once I installed the latest drivers, then the Saitek TPM throttle jumps the last bit. SO I can go from 0 - 11700 rpm without issue then it jumps to full power. there is no way to control power between 1500 and 2000 rpm. I have tired different planes, re calibrating the device. Nothing works. Help would be appreciated. It works fine on Xplane (under different user account). I had hoped to use FSX for the learning lessons.
