Zetec oil temp sensor:
worked fine for a long time, now has odd behavior;
shows sensible data for several laps, then after 20 miles or so the data starts to show random drops to 32 degrees, then spikes back up to 'normal';
frequency of dropouts increases as session time goes by;
but hours later in our next session, data again starts off sensible, then the dropouts start again;
happens every session.
changed the sensor for another new unit, same behavior.
with laptop plugged in and watching 'online' in the paddock, all the wire wiggling we could do wouldn't create the drop.
starting to wonder if this is an AIM issue and not a zetec/sensor issue?
(no one on the AIM forums has yet come up with a definitive idea)
(black is third lap, red is fifth lap, green is 8th lap)
thought welcome. thx
