Hello, John
Reading this topic I verified that you posted this:
Strat by setting/changing the following ini parameter in the [General] section of your FSUIPC7.ini file:
InitialStallTime=0
StartUpTuningDoneVersion=-1
DetectToConnectDelayAuto=60
The first entry will instruct FSUIPC to wait indefinitely for the first connection attempt and not time-out. The second will disable auto-tuning so these parameters will not be changed again by FSUIPC. The third parameter is the delay between when FSUIPC7 detects MSFS running and when it tries to connect, and it is this that you will need to adjust for your system, Try with 60, but time the period between when you see the FSUIPC7 splash-screen and when MSFS2020 arrives at the main menu, and then set this parameter to that time.
