hi everyone does anyone have any idea how i can mix BCM CAL files?

every time i do it dps gives me an error unless i flash a complete set ( full cal for another vin) i cannot take a specific cal file and combine it to mine

and create a new archive

this is the log file

ProgramLog.Txt

Can you explain exactly what you did to mix BCM cal files?

There are lots of cal files, but it's usually depends on OS so if you have one BCM with OS and other BCM with different OS, the chance is it couldn't be mixed.

I wanted to change files 5-6-7 from my stock bcm cal to another cars cal in order to activate some features such as remote start and fog lamp control

The reason i dont use the other vehicles full bcm cal because i will be losing other functions such as windows lock and children lock

2014 VIN is? U cannot mix them as Operational software is different. To mix selected callibrations require OS to be same.

I've had good luck mixing BCM cals as long as you stick to the same year.

Thanks to @Opelinsignia1985

I was able to know the issue it was different OS versions you have to stick with the same OS and mix and match however you want

Usually same year is with same OS :) in most cases. That allow mix and match calibrations.

from sps cache of two bcm,, just replace what calibration you want and convert to dps rar file,, if you swap calibration from already converted file it will not work
