I recently installed a new LC2 in my o2 housing, replacing my o2 sensor. I don't have a rear o2 sensor connected either.
I'm attempting to simulate a narrowband with EcuFlash/Evoscan. I have connected both the yellow and brown wires from the LC2 to each of the o2 sensor inputs at the ecu (pins 75 and 76) with no good results. In evoscan, my fuel trims don't move at all, and my STFT is at 24.8xxx volts constantly, regardless of which analog output is connected to the ecu.
I attempted to change the analog output setting in the LM Programmer, but it seems like the LC2 isn't taking the changes properly. If I set either output to 1.1v = 14:1 afr and .1v = 15:1 afr my gauge (Innovate Auto Timer) bounces between full lean and full rich. Then occasionally using the same settings, the wideband with show 10.8ish at idle.
If I got a bung welded on my downpipe for the wideband and then replaces the front o2 sensor, would that make it easier on me?
