 ====== Recommended Innovate LC-1 Installation ======
-Installation of the [[http://www.ecmtuning.com/product_info.php?cPath=28_29&products_id=60|Innovate LC-1 wideband kit]] is pretty straight forward.  The [[http://www.ecmtuning.com/images/forums/lc1install/LC-1_Manual.pdf|LC-1 Installation manual]] covers most of the basics for a general install.  We do, however, have a few specific suggestions and one grounding correction below.

 ==== BLUE wire - notes ====
 A good, solid high-current grounding point here.  The ECU pins listed above are good choices or you can try a good, clean chassis ground point too.

 **NOTE:** Do **NOT** connect the BLUE wire from the LC-1 to the ECU's sensor ground.  You will damage the ECU's sensor ground track if you do this.  **ONLY** connect the WHITE wire from the LC-1 to the ECU's sensor ground, **NOT** the BLUE.
+==== YELLOW and BROWN wire - notes ====
+The YELLOW wire from the LC-1 is defined by default as the "narrowband" simulation output of the LC-1.  Because you're using ECMLink, you can leave this wire disconnected (but isolated from ground with some heatshrink or electrical tape) and simply use ECMLink's [[v3narrowbandsim|narrowband simulation]] function instead.
+The BROWN wire is defined by default to have a mapping of 0V = 7.35 AFR (0.5 lambda) and 5V = 22.39 AFR (1.52 lambda).  This will work nicely using ECMLink's LC-1 datalogging item.  So run the BROWN wire into your selected ECU input for logging and then configure ECMLink to use this input for the LC-1 log item (ECU Inputs tab) and, optionally, for the narrowband simulation function as well.
+===== Sensor location =====
+We generally recommend installing the LC-1's wideband sensor in the front O2 location directly off the turbo.  That is, of course, if you plan to run without a narrowband sensor installed in that location.  We have been running our sensor in that location for years without issue.  We do not believe there are any "heat" concerns what so ever.
+===== Narrowband sensor =====
+When running an LC-1 wideband, you can simply enable [[v3narrowbandsim|narrowband simulation]] in ECMLink and use nothing but the LC-1's analog output for both wideband data and narrowband closed-loop operation.
+However, if you have the option of running both a wideband sensor and a narrowband sensor, considering doing so.  This is probably more common on a 2G where you can run the narrowband sensor to the factory Front O2 pin while logging the wideband sensor on the factory Rear O2 pin, but there are enough inputs on a 1G to do the same thing.
+The advantage to running a factory narrowband is that you get a good data point for checking up on the LC-1's calibration.  The narrowband sensor is **going** to switch around stoichiometric.  It's really good at that.  So as long as you're running in closed loop operation using the factory narrowband sensor, you should see an LC-1 logged value of about stoich as well.
+It's not a big deal either way, though.  So don't go out of your way to make it happen.  If it's convenient, great, give it a shot.  If it's not, don't worry about it.
