ok, so I went out and bought a brand new replacement temp sensor, results are as follows. resistance varied +/- 2% while testing for each reading. pressure 29.97
°C Resistance
16.5 740Ω
37 330Ω
53 161Ω
80 64Ω
99.6 34-35Ω
very similar results to previous test. I don't think I need the temp to be all that accurate, correct me if I'm wrong but I just need it to display when the car reaches its normal running temp (I have no Idea, but I will guess 80 at this time), and when it is beginning to increase past that, so say it lights up half the display at 80°C, 64Ω resistance (5 of 10 segment block for example) once it reaches 50Ω, guessing from the readings above that would be about 90 another 2 led's have lit up. if it actually reaches the 8th LED then I would like to incorporate the design on the 3914 datasheet (sorry for not mentioning this earlier) that makes the display flash once that LED is reached. so it wouldn't have much of a chance of getting past 40Ω (guess 92°C) without the driver (myself) having a visual signal that the engine is running over temp. does that sound like a possibility to you? or is my in-experience showing
