Adzn3k Posted December 2, 2018 Report Share Posted December 2, 2018 Hi guys, I've ready got an oil temperature sensor installed from my previous gauge is it possible to wire this in to my link ecu? The sensor type is a 2 wire one from a stepper gauge? Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 3, 2018 Report Share Posted December 3, 2018 You can use it provided you are no longer going to have the gauge connected. If you want a gauge still I would suggest it will be easier to use a separate sensor. Note however if calibration is unknown and you dont have a good idea how to check that yourself then it will probably be better to buy a sensor with a known calibration.

DanDan Posted March 2, 2019 Report Share Posted March 2, 2019 Hi I was wondering if Link ecu have a specific oil temp sensor which they have calibrated or what other oil temp sensor are people using with there Link ecu's? Thanks Dan Quote Link to comment Share on other sites More sharing options...

Thanks Dan If you want something from Link themselves, I believe this is the link to their unit - http://dealers.linkecu.com/NTC12_2 Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 3, 2019 Report Share Posted March 3, 2019 Most of the common Delphi and Bosch "coolant temp sensors" are only rated to 130°C by the manufacturer but I have found they are still acceptably accurate enough up to about 140°C (using our built-in calibrations) and will still continue to measure up to a max of about 150°C (less accurate). So, if your oil temp is normally below say 140°C I dont see any need for a specific "oil temp" sensor, a standard coolant temp sensor seems to do it fine.

DanDan Posted March 4, 2019 Report Share Posted March 4, 2019 Thanks for your reply's Also i was also wondering if anyone knows how to wire up the 2 way temp sensor plug with an external pullup resistor? Is it +5v - 1k ohm resistor - signal wire(an temp) and pin 1? Then pin 2 to 0v sensor ground? I hope you can understand that? Lol Thanks Dan Quote Link to comment Share on other sites More sharing options...

DanDan Posted March 4, 2019 Report Share Posted March 4, 2019 Thanks would i still need to wire in an external pullup resistor if I was to wire the sensor to AN Temp 3 (expansion loom) on the Mitsubishi Evo 1-3 link G4+ ecu? Thanks Dan Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 5, 2019 Report Share Posted March 5, 2019 No, the temp inputs have a built-in pull-up resistor. Quote Link to comment Share on other sites More sharing options...
AlexSavv Posted March 5, 2019 Report Share Posted March 5, 2019 If you’re using a dedicated temp channel (I.e.) AN TEMP 3, then there is no need for the pull-up resistor in the wiring as the ECU has them internally. if you are using a normal AN VOLT channel, then you need to wire the following: Pin 1: +5v with in-line 1kohm pull-up resistor... AND the desired AN volt channel Pin 2: Sensor ground I harassed Adam about this for ages xD Quote Link to comment Share on other sites More sharing options...
