Default Have LC-1 Experience? IN HERE!!!!

Ok, so I had my lc-1 set up to have the yellow wire outputting to efilive and the brown wire was running to nothing.

I just got a dynotune wideband gauge and my lc1 appears to be outputting in lambda rather than afr. So I open up the LM programmer on my laptop and I can't seem to program it. When I click program nothing happens and when I reopen the lm programmer the settings havent changed......

**Update, ok I found all the info and changed the settings to 1.0 for 10 and 2.0 for 20 and I set it to use afr's. It keeps the voltage settings but goes back to lambda every time. WTF?!?!?!

I dont understand how this will help anyways as i need it to output to my afr gauge.....and I need it in afr not lambda.


not trying to come off as a *****, youre confusing me. please make a little more of an explanation



Ok so I tried that and it seems to have accepted teh setting but it has not changed the display from reading 00.7 to 1.2

we normally calibrate them using efilive but using the lm programmer after you change the setting to afr then go into advanced settings and change the gauge read speed to 1/3 second and see if that will program it for you

Did you remove power to the LC-1 after every software change with LM programmer? Simply closing out LM programmer will not make the change permanant- you need to power down the LC-1 and "reboot it."
