928sg Posted January 15 Report Share Posted January 15 title says it all. I've already used my temp inputs and wanted to add cooling fans and wanted to add another sensor in the radiator. Current temp sensors are Engine coolant (on engine side of thermostat) Trans temp Oil Temp Intake Air Temp Quote Link to comment Share on other sites More sharing options...

essb00 Posted January 15 Report Share Posted January 15 You can connect additional temp sensors into AN Volt Input - you have to connect a 1KOhm external pullup resistor. On the still unused Analog Input, select 'GP Temp (Ext Pullup)'. Then select the calibration table you have set for the sensor you installed.

928sg Posted January 16 Author Report Share Posted January 16 anyone know of a NTC sensor with m22x1.5 threads? Quote Link to comment Share on other sites More sharing options...
928sg Posted January 17 Author Report Share Posted January 17 to add PWM fans does the Link ecu need to have a temp sensor in the radiator, for it's logic to increase fan speed? my logic would say yes, because the engine temp coolant sensor is on the engine block side of the thermostat. Am I correct in my assumption Quote Link to comment Share on other sites More sharing options...
Confused Posted January 17 Report Share Posted January 17 With my stock Mitsubishi ECU, and subsequently how I've copied the logic, it relies on only a temperature sensor in the engine. Once the thermostat is open, the radiator and engine are closer in temperature, and this is when the fan becomes relevant. So, I think you'll be fine without needing to add extra temperature sensors.

928sg Posted January 22 Author Report Share Posted January 22 I'd rather run the fans based on the actual coolant temp in the radiator.... Quote Link to comment Share on other sites More sharing options...
Confused Posted January 22 Report Share Posted January 22 In that case, you've got your answers above - you can use an external pull-up resistor to add an extra temperature sensor, and if you ignore the "Engine Fan" functionality completely, and set up your own GP PWM table with your new temperature sensor as one table axis, then yes, you can vary the output based upon this sensor But, you may be making it more complicated than necessary, I at least was just suggesting how an OEM has done it without a separate sensor.
