hi stu and thankyou very much for your detailed reply and obvious time spent researching as well.
the working one which is perfect and the one that went recently faulty have both been studied very carefully .one was for a manual and one was for an auto (no's 0.......017 and 018).both do identical functions except hold a different idle speed.
i spent a few evenings looking for differences in the two and found 4 resistors different to each unit. i swapped these from unit to unit and also replaced the electrolytics in the good unit too.
so far i can confirm that the resistor swap worked. the manual ecu now holds auto idle speed and vise versa and both units ( including the faulty one ) are working ok so far. i did resolder loads of joints even thou they looked ok but as you know some cold joints are not always visible.
pm sent too .cheers.
