Smiffy69 Posted November 28, 2015 Share Posted November 28, 2015 Just been out for a Blat (taking SM25Ts advice on driving it more ) and plugged in the easy map and did some logging - Not to find a particular problem just for interest.The run was for about 30 mins and from a cold start with a mix of road types and a bit of motorway. Everything looks ok except the the oil temp when sitting idling say at lights or low revs the oil temp was around 80 deg when giving it some effort it would drop down to about 35 deg which seems a bit low. My original thoughts were that under revs the oil pump is working harder and the pressure is up so the oil would cool more as its flowing around the engine faster but I would have expected the oil temp to rise over time I was out . The only heating / cooling would be via a modine so I had expected it to run more consistently at around 80 degsI'll go for a longer run to see if it just takes longer for the oil to heat up than I expected.Is this something you would expect to see or do I have a problem ... with the car that is not personally !

Member Jonathan Kay Posted November 28, 2015 Member Share Posted November 28, 2015 What was the air temperature? Do you have corresponding water temperature measurements?Jonathan Link to comment Share on other sites More sharing options...
Smiffy69 Posted November 28, 2015 Author Share Posted November 28, 2015 Air Temp 11 Deg water 90 deg +- 5 deg Link to comment Share on other sites More sharing options...
F355GTS Posted November 28, 2015 Share Posted November 28, 2015 Doesn't sound right, giving it beans would increase temps due to increased engine friction and it wouldn't change significantly at idle unless it stood for ages. The values you are giving sound more like pressure in reverse ie should be high on the move, lower at idleThe modine should help to keep temps stable inline with your water temps Link to comment Share on other sites More sharing options...
Smiffy69 Posted November 30, 2015 Author Share Posted November 30, 2015 Hi Mark,That's what I thought and it does seem to be the inverse of the pressure - I also would have thought that there would be some thermal inertia to the oil (like the coolant does i.e. it doesn't suddenly change temp )which then makes me think "do I have a faulty Sensor" ?Does anyone know where the ECU on a Duratec gets the Oil temp reading from ?cheers Ian Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted November 30, 2015 Member Share Posted November 30, 2015 Is a "modine" an oil-water heat exchanger? And there's no separate oil cooler? Does it have a thermostat or any other controls?Jonathan Link to comment Share on other sites More sharing options...
Smiffy69 Posted November 30, 2015 Author Share Posted November 30, 2015 Hi JK - yes a modine is a heat exchanger .....Drama over I have since discovered that the Duratec does not come with an Oil Temp Sender so the readings I have off the easymap logger are not valid. I therefore assume this data is not required in the Native CC ECU map.Ian Link to comment Share on other sites More sharing options...
