Modified GM VSSB – To Adjust for Different Tires / Gear Ratios – TBI

Price on application

These VSSBs have been modified with 6 pin DIP switches to enable calibration for different tire sizes and gear ratios.  This style works with ’87-95 style ECMs like the 1227747 and 16197427, instructions are included.  If your setup has the DRAC built into the gauge cluster, this probably isn’t a good replacement. p/n WTB006
