I've actually tried to wire this up today, but the problem was that my car did not come with rear O2 sensors, so there were no wires to use at all, at least we did not find them, because I thought that there will be at least unused wires inside the loom somewhere. Anyways I might give this another shot and try to do a new wire to ECU pin #68, however I am not even sure that this is even physically connected in the ECU itself. What do you guys think?  I think you're a lucky bastard. |

yea we have the two spare heater wires that we can use for anything...
maybe 1 for switched power, the other for nb simulation (not sure you'd want it for anything though)
It's a heater circuit. |

yes, i am saying you can use one of the existing heater wires for power to the pump...

I'm pretty sure the ECU is identical to a two point narrowband, and you will be able to just wire it to the ECU connector. You will need the RAM location for uushk_w too. |

All right, I am going to give it a shot tomorrow. Thanks! EDIT: Oh and I think I want pin #69 not #68. |

So I had to pin it to the ECU connector, to pin #68 and it works like a charm! Thanks guys! uushk2_w

Does this mean that we could use a PLX DM-100, which can display OBD-2 values, to monitor two linear analog outputs? One gauge for two wideband inputs AND all of this: RPM
Vehicle Speed
Throttle Position
Engine Load
Absolute Engine Load
Engine Timing
Air Intake Temperature
Coolant Temperature
Ambient Air Temperature
Intake Pressure (MAP)
Air Flow (MAF)
Fuel Pressure
Fuel Pressure Relative
Fuel Level
Barometric Pressure
Catalytic Converter Temperature
ECU Voltage
OBD Type
Short Term Fuel Trim (Bank 1)
Long Term Fuel Trim (Bank 1)
Short Term Fuel Trim (Bank 2)
Long Term Fuel Trim (Bank 2)
Oxygen Sensor Voltage1 (Bank 1)
Oxygen Sensor Voltage1 (Bank 2)
Oxygen Sensor Voltage2 (Bank 1)
Oxygen Sensor Voltage2 (Bank 2)" This is about $500 directly from PLX(not looking elsewhere) for a, in my opinion, great solution for tons of monitoring. |

Not over OBD. It only reads specific parameters required by OBD protocol. You would have to get the extra module or figure out another external input. |

Hmmm, so the OBD Parameter, that would be read by the gauge, "Oxygen Sensor Voltage2 (Bank1)" isn't "uushk_w"? And same for Bank 2 but "uushk2_w"?
I was going to buy two LC-1 units for wideband and feed them into the ECU but also was hoping to read out the two LC-1 sensor's linear outputs via the OBD feature on the gauge.

You need to be able to log the raw voltage. That will log ushk_w and likely be a constant 1v. |

Ok, Thanks phila.
I'm sure there's a way to change what the OBD parameter looks at, i.e. uushk_w instead of ushk_w, but that programming ability is above my head at the moment.

Yes, there is, just trace through references to the variable, and when you land on a HUGE graph that IDA might even not display with default settings, you know that's the spot you have to change  |

I'd love to dive into disassembly but I'm not sure I'm quite ready for that. I need to spend more time with the FR and become more familiar with the "BIN" side of things before I start disassembling, even if I'm able to, to figure bit setting, OBD parameter calling, etc. |

If you're talking about replacing ushk_w with uushk_w in the standard OBDII PID, yes it can be done, but it will require disassembly of his file. |

That's what I was referring to - assuming the file is disassembled, about how to find the right spot. If you've ever gone through the protocol code that deals with the PID's then you should know what graph I am talking about. Impossible to miss, as the first time you see it you go:  |
