As most of you know I did an axle swap from 3.42:1 to 4.10:1 ratio. The changes have been tuned into the PCM for shift points etc. and it runs fantastic with no drive-ability issues.
After I drive for several miles the abs system shuts down and ABS/Brake lights illuminate, also I am recording excessive mileage of about 1.4 miles to 1.
I have researched this extensively and can not find a direct answer.
My Question: Which unit do I need to focus on? Can the BCM be reprogrammed for the 4.10 axle? I know that the instrument cluster is controlled by the BCM, so that is where i suspect I need to go. However some say it may be the ABS module itself? Does anyone know the answer, or a link to where the answer may be found? I now have a way to correct the mileage so I would like to get everything back into check.
Maybe someone with a tech 2 could connect to their truck and see If the option exists to make the necessary changes to the BCM?
Any help is greatly appreciated!
