My speedo does the same thing no matter what I put in the ratio boxes. Symptoms of what??????? I have flashed twice each with M6 images and A4 images and no change. Wire colors matched when I spliced. Bad sensor? Bad reluctor? Appears to be approx 2X fast which I understand to be normal for the swap I have done, 17 pulses (A4) to 40 pulses (M6). However a change to a 1.76 ratio has NO effect on the calibration of the speedo. What is going on??????????????????
