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. | A good, solid high-current grounding point here.

The only major concern with connecting something to the ECU's sensor ground is that it might draw too much current and [[blownsensorground|blow the ECU's internal sensor ground track]]. But we've measured current draw on the WHITE wire to be a measly 45-50 mA. This will not cause any problems on the ECU's sensor ground circuit. | The only major concern with connecting something to the ECU's sensor ground is that it might draw too much current and [[blownsensorground|blow the ECU's internal sensor ground track]].

**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. | **NOTE:** Do **NOT** connect the BLUE wire from the LC-1 to the ECU's sensor ground.

+ | ==== 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. |
