thegallguy: approximately how fast are you going when your speedometer indicates 100mph? If you feel that are going about 50mph at the time, it would require only a fairly simple circuit to cut the ABS sensor output frequency in half and could be done digitally, i.e. for each two pulses received one pulse is put out. This is a basic frequency divider circuit using "D" flip flops that I studied in engineering school decades ago; you can now buy ICs that can divide by any integer. Maybe something like this this would be close enough.........
