Hey gang,
I have the MS-PNP box for my E30, and I'm attempting to install an Innovate LC-2 wideband oxygen sensor. I have the back module with the four wires (red, black, yellow and brown). I have my red wire hooked to the switched 12v pin, the black one to the ground pin, and the yellow wire to the oxygen sensor signal pin, all in the back of the options port on the MSPNP box. my brown wire I have taped off. The issue I'm having is that the LC-2 will not complete it's free air calibration, it endlessly flashes the green lights twice per second, indicating that the sensor is heating up. The manual states this process should take 30-60 seconds, but it kept flashing for roughly 10 minutes before I turned it off. I tried Googling this issue for help, but only found something similar for a first gen Miata, where the OP was told to not use the MSPNP power and ground pins for a wideband, citing that the LC-2 needs 5a 12v and not the 0.5a that the ECU supplies, and that the ECU should never be used for a ground for this. Can someone with experience please advise?
