and how to set the correct pulse , i have a feeling either the sensors not aligned or the timing is out , so looking for general info

Have you searched all the Orac circuit diagrams - there may be more info in there

thanks found it !

If it's the same as the one on the starturn (which I think it is) you need to supply the sensor with a 12v supply and you will get a 5v output from the signal lines.
