    Reading Resistance OBD 1

    Ok I got a 1990 Mazda 929. I want to monitor most of the engine sensors from a computer. All of the sensors operate by sending resistance to the ECU. I have the splice harness from Mazda's engine signal monitor. I need something that can read most of the 67 sensors in this car. Anything out there that can do it?

    You want to read the sensors directly? not via serial? If that's what you're saying, a few fusion brains may be able to handle that job.

    can it be read through serial??? I have a splice harness and the technical specificaitons for each sensor. instead of connecting a multimeter, reading the resistance of a sensor and then going through the formula just to find out whats the coolant temp. I'd like to just have it at my fingertips . and see whats what so I don't blow my car up.
