Still trying to identify a problem I have with power drop in the upper rpm range. Looking at the CAS at the moment, checked the voltage of the base setting (reference, pin 41/51) measured at the ECU and it fluctuates by half a volt or more for no good reason. Checked the voltage of the position signal (42/52) and it's spot on and steady as a rock, changes slightly for increase in rpm...
Can anyone please tell me if the voltage of the reference or 'base' setting should be stable for stable idle rpm?? I would have thought so. If so, can this be due to a dodgy CAS or would that be too easy??
No error codes but timing mysteriously jumped to 15 degrees advanced a few weeks ago - timing belt has been replaced and is correct.

Any input appreciated.
