Has anyone ever published the broadcast codes for the DRAC/VSSB?
Example: I own a '92 8 lug K2500 w/ 4L80E, 3.42 gearing and stock 245/75/16 tires.
The broadcast code on my oem VSSB is QXL w/part #16158915.
I replaced the 245's with larger tires and bought a 're-calibrated' vssb that was fairly accurate as far as road speed, and although the ABS light didn't come out, the ABS functionality was was never really right.
I found a website that shows VSSBs with most oem broadcast codes. Do these broadcast codes correspond with oem gear ratios/tire sizes? I don't want to alter my original factory VSSB but I'm trying to find one for 265/75/16 tires and 3.42 gears.

There were quite a few posts and I believe instructions on here a number of years ago on how to adjust the jumpers on the board to calibrate for tires and gearing.

I just tried a search on VSSB calibration and found several old post dealing with the VSSB and ABS problems.

There used to be a table of values somewhere in the member's section of the web site. Can't seem to lay my hands on it right now, though.
