Coolant temp sensor
I'm setting up my Hydra some more and I am curious if the SVX coolant temp sensor reads the same as the newer (01-09?) coolant temp sensors. I have a good coolant temp sensor calibration for an 02 WRX and would like to use these settings if they are the same sensor build. I know the SVX is a 2 wire and the newer are a 3 wire because the incorporated the gauge switch into the sensor. I have a calibration I am using currently for the SVX however I'm not sure it is correct and this is an important setting for the engine. I'm having trouble finding a good accurate voltage calibration for the older 2 wire sensor.

Re: Coolant temp sensor
I posted a calibration curve in my megasquirt thread.

Re: Coolant temp sensor
oh awesome, you found the actual bosch paperwork for it. Now I just need to figure out what the Hydra uses for a pull-up resistor in the circuit so I can calculate all the voltages out.
