I am still getting a P0102 in my scanner. I do not get a light but P0102 is still reporting.

I disabled the MAF sensor by:

Set the Engine Diagnostics->Engine Diagnostics->MAF->Parameters:
• {C2901} MAF High Frequency Fail 1: 1Hz
• {C2902} MAF High Frequency Fail Limit: 1
• {C2907} MAF Test Min Engine Speed: 300 RPM
• {C2908} MAF Test Min Run Time: 0.1 seconds

Set the Engine Diagnostics->Engine DTC processing Enablers:
• P0101 ‘C’ Non Emissions
• P0102 ‘C’ Non Emissions
• P0103 ‘C’ Non Emissions

Set the Engine Diagnostics->Engine DTC MIL Enablers:
• P0101 ‘No MIL’
• P0102 ‘No MIL’
• P0103 ‘No MIL’

Set the Transmission Diagnostics->Transmission DTC Fault Max Pressure Enablers
• P0101 ‘No’
• P0102 ‘No’
• P0103 ‘No’

Is there another setting setting I need to change?

Bill, this is what you want, all MAF-less cars should report that DTC but never light the MIL. The reason is the PCM needs to flag for itself that the MAF has failed.
Don't worry, you did nothing wrong.
