OK, having found out that I could enlarge that photo to make it readable, I see what the gauge is saying and I must admit I made an error in considering the oil temperature reading, as i am old school and was thinking along Fahrenheit lines, where a normal oil temperature is anywhere from 230 to 260 degrees, which does put 114 C. close to the 230 F. mark.
I also see that gauge is showing the ignition timing setting and that would play a role in the temperature that the engine operates at. So this adjustment could marginally effect oil temperature as it relates to ignition timing, which is what the technician would have been playing around with through the ECU settings.
Apologies to the tech for my misunderstanding, but calling oil "coolant", in the sense we normally think of coolant (anti freeze), was what got me flying off in a tangent.
Now, does that solve the engine light problem though, which is what this thread seemed to be focussing on?
