Efie install
I recently installed my efie on my 92 Chevy k1500. I installed it in my glove box so I could easily set it. I have it connected to a good switched power and ground as we'll to the o2 sensor wire at the ECM. My problem is when I start the truck I get a slight hum and both green LEDs flash rapidly. The red light does not come on at all. I have tried multiple power and ground points with the same end result. I am sure I have the correct wire for the sensor because it gains voltage as it heats up starting at about 130 and climbs to about 600mv. If I test the wires at the efie I get what is to be expected. But when I use the test ports on the efie I get significantly lower numbers and have no control on the voltage.
