Edit: the rear o2 sensor..
Edit again: I don't know a whole lot about it.. but would it be possible to have the ECU control a wideband o2 sensor (so we could go buy the Bosch sensor instead of an LM-1 or another controller) ? Basically all it does is heat it sensor, which the ECU does for the stock sensor, right?
As far as I know. LC-1 is almost the same as LM-1 without a screen. For LC-1 to show the AFR, basically you have to plug the unit in and use the laptop screen to show the result or purchase their optional XD-1 standalone AFR 60 mm. guage.
As for the out put these units output range is 0-5 volt while our stock 02 sensor is 0-1 volt. You can not just replace stock 02 with Bosch unit. This is why you need a "wide band controller" which modifies signals to any form that you like. I dont think removing front 02 and replace it with Bosch wideband unit is a practical solution since it's very time consuming process. And a Bosch WB has quite a short life (200 hours) and expensive to replace. Most tuner usually take theirs off after the tuning sessions.
For the replacing rear O2 sensor with Bosch wideband, rear sensor is not the primary o2 sensor for ECU to monitor AFR. It's mainly for Long Term Fuel Trim.
