Tach Working


After mounting the new Hall Effect sensor and verifying its signal with the scope, I hooked it into the tack input and viola it worked. Programming the tack to recognize the incoming signal as a 1 pulse per revolution is a piece of cake with the Speed Hut tach. I also quickly reprogrammed the shift point on the shift light LED’s to 3K instead of the 2K RPM that they are set to in the video. Because of how close the radiator is it took me over 3 hours after I actually made the sensor bracket to get mounted. I had to put it on and take it off to get the position of the sensor right and then again to get the gap between the flywheel and the sensor into the sensor manufacturers recommended range.
