Did I not include a little diagram?1. On the Dsub connector, the wire on pin 15 is for the wideband signal, and I'm guessing that the wires on pins 1-4 are for the TPS signal - which pins on the toyota TPS do the wires go to?
#1 is 12v out.
#2 is Ground out
#3 is Sensor Ground out
#4 is o2 in.
#15 is probably has nothing mating it. I reserve that for the EBC.
These can be used to wire up your LC-1 and input the wideband.
I'd wire the TPS back through the factory wiring at the TPS connector. You'll need to add a 5v jumper wire inside the case to power the signal and cut off one resistor.
Once you are running with the LC-1 you have no need for the NB. You need to unplug from the factory wiring if you have both installed (they both wire to the sam einput). I wouldn't ever use the NB in any operation.2. You set up the MS to use a wideband, and I'll be using an LC1 right before the cat to get the tuning done. I've also got a narrowband o2 in the stock location - is this now superfluous? I've run LC1 a couple of years, and am wary about it being my full time o2 sensor, as I've already had one Bosch sensor failure. It makes more sense to me to get the tune sorted out with the LC1, and then use the narrowband for day to day closed loop operation. Thoughts on that? Would it just be the software setting change in MS, or would there be a solder change required?
