On my 60 D-100 I went from 4.10 gears to 2.76 and from 6.70x15 tires to 235-75R15 and needless to say my speedo was off by a mile. I looked in Hemmings and found a speedometer company and he said to drive it 10 miles and tell him how far the odometer showed. He sent us an adapter that screws on the transmission where the cable goes and then put on the cable. It is exact. Since your speedo is electronic I would think the adapter would go on and then put on your pulser. At any rate your friendly speedo man will have all the answers
