Help with speed sensor
Posted: Fri Jul 30, 2010 10:59 amI’m sure somebody on this forum can help me with this but it has me stumped.
What I have is a Falcon that has a M600 in it. My problem is that I’m trying to use the speed sensor that was being used as an input to the AIM sport dash. The sensor is a Honeywell 17mm picking up on the 4 bolts on the tail shaft/pinion flange.
What I have so far is that i’m using the Dig2 input and have a signal and have done the speed calibration. The problem that I can’t sort out is that once the tail shaft gets some rpm into it the speed starts to fluctuate. Jumping from 80-190kmh when the car is moving around 90kmh. But it will do it all speeds
From what I can work out is that because the 4 bolts are not evenly spaced on the tail shaft it is causing the speed to do what it is. But I can’t work out how to stop it!!!
Thanks in advance.
