Please Verify WB Open Loop Settings

Ok I want to make sure I have not missed anything while doing Wide Band Learns. I have these settings done. Sunday is my day to play and I want to get as many learns run as I can today. Want to make sure Im not missing something for the best Wide Band Learns.
EBL FLASH-II

BIN Changes:
*Flags - Option Word 4 - Bit 0 - OpHwy - SET/Checked - Enables Open Loop Lean Cruise
*Scalars - Closed Loop - CTS Threshold - (set to max 149.75) Disables Closed Loop
*Tables - PE TPS% Enable Threshold - SET to 100 (Disables PE During Wide Band Learn)
*Tables - BLM - RPM Learn Threshold to 450/6000 ( Enables WB Learn to 6000 RPM)

When not doing learns
BIN Changes:
*Flags - Option Word 4 - Bit 0 - OpHwy - UNCHECK
*Scalars - Closed Loop - CTS Threshold - (Set back to 48* C is stock)
*Tables - PE TPS% Enable Threshold - SET to 100 (Change back to stock table settings)
*Tables - BLM - RPM Learn Threshold to 450/6000 ( Can leave with no issues)

Re: Please Verify WB Open Loop Settings

For WB learns only need to set the closed loop enable temperature high.

Leave the OpHwy cleared, leave the PE TPS% threshold table as stock (or tweaked as required), and the BLM RPM threshold doesn't matter. As the ECM won't go into closed loop fueling with the CTS threshold set high.

RBob.
