Escort Cosworth MAP Sensor
I have a 3 bar map sensor fitted at the moment. Does anyone know the ECU pins and expected voltages for various boost levels ? Also, is it true that it has to be mounted upside down, and the case seperately earthed ?
Thanks.
Thanks.

I've found that life I needed.. It's HERE!!
Mounting upside down is good practice. It allows fuel to drain from the sensor.
Signal is on ecu pin 15, Ground on pin 11. Voltage level at Key On, Engine Off is approx. 1.5V at sea level. 1 bar boost (2 bar absolute) approx 3V, 2 bar boost (3 bar absolute) approx 4.5V.
