Setup LC-2 to read as Lambda Scanner 3.0

[jpb1972]

I'm trying to setup my lc-2 to read as lambda. I figured out how to get it to display AFR on the Channels list, but that's as far as I'm getting. Can't figure out how to get Lambda to display on my "Chart vs. Time". Any help would be appreciated.

(My LC-2 in connected through my MPVI)

I know my config is a mess, but I'm still figuring stuff out.

Thanks

We don't have a built in LC-1 or LC-2 lambda transform yet. Do you have a link to the default scalars?

Also, with the innovate LC products, you can adjust the output, which is best to minimize voltage offsets.

I've added it to tomorrows 3.0, where 0v = .5 lambda and 5v = 1.5 lambda

Awesome. Thanks!
So there's no way for the end user to set up user configs like 2.24?

OK, thus far I selected the new Lambda transform for the LC-2. In my channels list it is showing AFR still. Do I have to record a new log for this to work right? There are several pieces to this puzzle I'm sure I'm not getting.

Are there new help files for 3.0 that I can refer to?

You probably selected the LC-1 under Air/Fuel ratio group, not Lambda group.

That was the first thing I checked. That's why I'm wandering if I have to do a new log for it to display properly. But no, the LC-2 under Lambda group in Oxygen Sensors was selected.

yes, you must transform the LC-2 using the EQ ratio (lambda) transform, it's different than the lc-2 afr transform.

Don't forget you also need to connect to the LC-2 with their config app to change the default output from afr to lambda.

The settings were already done, as it was working with 2.24.

[Keith@HPTuners]

2.24 did not have built LC-1 or LC-2 eq ratio (lambda) transforms, only air/fuel ratio.

I understand that. I was able to make it work through custom pid. Whatever it was, it worked.

UPDATE: Connected to the car, uploaded config to the MPVI and it seems to work. For some reason it (my WB lambda) froze. Once I stopped the scan and restarted it the lambda reading began to work again.

Any ideas?

There is an ongoing issue with external inputs freezing up. The cause has not yet been determined (as far as I know anyways). There's a big thread about it in this section where several people are trying to narrow down what is causing it

I did see this. I've been scouring the 3.0 New Release thread.
Thanks for the reply.

is there a secret handshake to get a lamda transform for the afx-ngk ?

[schpenxel]

The transform for that WB in lambda is included in Scanner. Update to latest if you aren't already using it.

thanks---brain farts happen with us old guys.

Please add the MTX-L to this as well.
