My 1997 Mitsubishi Eclipse GST emissions codes are coming up "not ready". My mechanic gave me the readiness test procedures from ALL DATA and I drove the car through those with no effect. Then replaced the ecu and did the procedures again with no effect. It is only the codes having to do with emissions(o2 sensors, catalytic conv, evap, etc.) What else could it be. Gotta get car to pass emissions inspection.

Check that the red wire is active at the O2 sensor, as that should be the heater wire for the sensor, if it is not working the sensor will take some time to get to temp and this may set your code, look here first.
