BigBoiMR2 Posted March 13, 2019 Report Share Posted March 13, 2019 Hello, I'm looking at adding an oil temp sensor to my Link ECU, it it the MR2Link PNP V3 ST205 version. In the ecu settings I have used an temp 1-3 for ECT and 2 IAT inputs one pre and one post intercooler. I would like to add oil temp as well. I see AN-Temp 4 is unused Looking at the pinout information for the ecu, I am unable to find An-Temp 4 on the main plugs or any of the expansion connectors. Does it exist? Also if I wanted to add a fuel temp sensor later would it be possible or would i have to replace one of my IAT Sensors? Thanks, Cameron Quote Link to comment Share on other sites More sharing options...
Richard Hill Posted March 14, 2019 Report Share Posted March 14, 2019 No. There is no an temp4, but you could use a spare an volt input with a pull up resistor. Quote Link to comment Share on other sites More sharing options...
gtihk Posted March 14, 2019 Report Share Posted March 14, 2019 You can use an external 1K resister pulled up to 5v. Quote Link to comment Share on other sites More sharing options...
BigBoiMR2 Posted March 14, 2019 Author Report Share Posted March 14, 2019 Ok, I will get an expansion connector and some external pullup resistors so I can add the extra sensors I need. Thanks! Quote Link to comment Share on other sites More sharing options...
