LC-1 EGO not appearing

[JamieN]

I've connected the LC-1 as per its manual. Its 'brown' output is to 'pink' O2; the grounds are to the system ground; I do read a correct and variable (when holding an unlit lighter at the sensor) VDC at the connections involved. In the configurator I have 'set' LC-1. I'm not seeing any reading, or 'sense' at all on the Microsquirt AFR screen though. I do have sensible readings from TPS and MAP showing on screen. What else can I do? I haven't checked the continuity from the O2 lead to the board but doubt if it's a hardware issue, self knowledge means the issue is probably self made! All help seriously welcomed.

First, are you getting an RPM signal? The code only updates the EGO reading when it gets a tach pulse.

Second, have you calibrated it for the LC-1 under Tools -> Calibrate AFR Table? you'll need to do this in addition to the Configurator setup.

Matt,
Thanks for your response. No and Yes are the answers! I wasn't aware that the EGO/LAMBDA/AFR reading would only change with the motor turning or an RPM input. I was trying to verify the sensors prior to starting the engine. The fields have been reset in the AFR settings. I'll be trying again in the morning so possibly will be back 'pleading' for guidance. Just out of interest as I didn't see that in the manual; I assume that it is in the manual!
Cheers again.

It's not all that clear from the manual, admittedly. Sort of a quirk of the code, and it's responsible for a lot of confusion.

I have the same problem, engine is cranking and running, but no signal. Analog2 (brown) to O2 (pink) gives signal with voltmeter, but does not show up in Tunerstudio/megasquirt or logviewer. I have a db digital gauge connected to analog1 (yellow) which works fine(set up as analog2). I have setup the default LC-1 in tools - calibrate AFR. The rest of the sensors work fine. HELP

With the help of A2TURBOs msq I found one major error: Cranking speed, it was set to 1500 rpm. Set it to 300 rpm and I think this will solve my issue. I believe that while cranking the 02 sensor is inactive in uS.

[sundby]

Yep, it is working now (cranking set to 300 rpm) .

I was about to call for help when I saw this thread, problem solved Thanks !!
