EFIE not influencing engine
PROBLEM with EFIE,
My car is Australian,Ford-Falcon, 1993 EB 4000-cc.
I have installed EFIE Quad,narrow band digital,wired as fallow;
Port 1 + (positive}
Port 2 - (ground to car)
Port 7 to 02 senser close to c.converter
Port 8 to computer
Reading from 02 sensor .920 mv.EFIE set to 350mv.It tells the computer 1,270 mv,yet it has NO effect on engine porformance,then I lower the voltage to .120 mv.
It then tells the computer 1.40mv.But still NO difference.What shall I do ? Please help.

RE: EFIE not influencing engine
If you are reading .9 volts straight from the sensor, then it's not the EFIE. It's the sensor. The sensor should be fluctuating between .2 and .7 volts. It sounds like you have a completely shot o2 sensor that is basically telling the computer that the mix is rich all the time. The computer will ignore that because it's programmed to recognize a shot sensor.

But before you go forward, measure again, but use the sensor's signal low as the ground for your meter. Lets make sure you're readings are completely accurate.
