You can go and lower the temperature value which is sent from the sensor to the ECU. For example: At 40 you have 280 Ohm. At 60 you have 130 Ohm. What you do now is: Put a 150 Ohm resistance in series to the sensor and at 60 degrees real temperature the ECU gets a value of 40 degrees temperature. Or, if you want to find out the best working resistance value put in a potentiometer 0-500 Ohm and have a play with it. As soon as you've found the best resistance value replace it with a fixed one, bit heat shrink, neat and tidy. And you know that the temperature shown on your gauge is behind the real oil temperature always "X" degrees. But, you have to find out if the resistance changes linear or not. If not you might be better off with the 0-500 Ohm poti. Cost only a few cents. Regards, Berni
