While cold it is in OL, you may have to correct table A008 OL ECT Commanded Fuel Multiplier.

Did you look at log file and the tune file. I have A008 set to 1.00 after 104f. I have spike at on cold starts and some times when the truck already warm.

Yes I have...
that looks like it's still in OL until frame 1010...
B0101 looks low during OL warmup, trying multiplying those few cells in B0101 by 1.20 and see what happens.
