Hi,
I've recently installed a dash 2 (nothing else) into my kitcar (not iva'd yet).
I've been having a problem with the wheel speed sensor, it's a bolt type hall effect sensor from demon tweeks.
I've done some maths and as I installed the sensor on the prop shaft I get too many pulses (13952) max is 12000.
I installed 2 tabs so I only get 2 pulses per rotation rather than 4 and entered 6976.
I tested the speedo and it was giving roughly the correct reading but when I got to 25mph it stopped registering any speed at all.
Is there a simple solution to this as I seem to solve 1 problem and create another?
Cheers, Steve

Hello,
If you are using the sensor as an RPM pickup, you must check that you have a big enough "target" to trigger from, most of our RPM inputs need at least a 1mS pulse to trigger from. Given a pulley diameter of "D" (in mm) and a maximum RPM, then the minimum target size (in mm) can be calculated from "RPM x D / 20000".
Alternatively you can use one of our pulse dividers that will convert the signal into a 50% duty cycle.
