Hello,
the camshaft pulleys between AAN and ADU engines are different. If we look at a engine which is turned to the top dead center of Cylinder 1, the positions of the AAN and ADU camshafts are different. That is why AAN camshafts shall be used with AAN pulleys and ADU camshafts with ADU pulleys.
in addition the timing plate for the hall sender inside of the pulley is different. From looking at it (and asuming the camshaft pulley is rotating clockwise) the timing plate of the ADU pulley seams to reach the sensing element earlier then when using the AAN pulley.
And here we come to my question: if I use ADU calibrated ignition timing maps with AAN camshafts and pulley, is the timing then overall shifted? (Because of the different hall sender plate inside of the pulley).
And if the AAN pulley triggers the hall sender for ignition later, can I compensate that with a constant offset on the whole ignition map, let‘s say with +1,5° Ignition advance?
My goal is to reuse a RS2 ignition map, but with using AAN camshaft and pulley.
Best Regards,
Daniel
