Engine Calibration 12607032 for OS 12587603 in 5.3L LM7
I used "04 Chevy 1500 4x2 LM7 12587603.bin" from this forum as the donor OS for an '03 5.3L LM7. I looked up the VIN for the 603 OS in TIS and below is the output. It appears there are new calibrations for the Engine and Engine Diagnostics to solve "Calibration to address oxygen sensor failures during cold ambient starts." Does anyone have a bin with these calibration IDs or more details of the problem it solves? I'm guessing this change would be applicable to all the 2004 vehicles.
