    Fuel gauge calibration

    I have a 99 GMC Yukon that I swapped a 05 Cadillac LQ9. The original black box PCM has a BCC of CMUF. The donor ECM is a P59 and I am running a 603 operating system. I am having trouble calibrating the fuel gauge. Current BIN and the XDF file are attached below.


    I cannot find the bin file for the original black box so that I can to my current PCM. I have played with various calibrations in my donor PCM, mostly F0501 thru F0510, and have not found the magic combination.


    Any help with which parameters to change or a proper BIN file for the original black box PCM would be most appreciated
