LM-1 Programming & Settings

[RevGTO]

Here is a log file. It shows a little more variation than the one I described, but that one got deleted.

Change analog out 2 to
0.88333v @10:1 AFR
4.21667v @20:1 AFR
Then do a quick log & post.

Or you can use this one that doesnt give you much resolution. (Original lm-1 settings like you have programmed in at the moment.

The LM-1 changes those voltage values when programmed in to 0.879 and 4.215. Does that make a difference?

It's been a while since I played with the analog side of things, but I do remember the values being changed slightly & leaving them as is.
There is a lot of noise in the grounds showing in your last log. Mine was only around a 0.3v swing but yours is around 0.7v. You will need those full range settings to smooth it out.

Ok, great, thanks. It's midnight here so I have to call it day. I'll log tomorrow and post up my results.

Note: This sae_generic revision contains AD1-AD2, whereas your previous recommendation had it the other way around (post #16).

Yeah, I was getting confused between what wire was in what slot etc. Thats why it was easier to get you to post the log & file so I could play with it here.
Once you have the log with the better resolution settings I will set up the generic txt file again.

A quick log with those LM-1 setting gave AFRs at 25:1.

There is something seriously wrong with the analog voltages in that log. Check your connections.

I suggest you program it, build your PID and trust what you see in the software.
The LM-1's digital display is going to be a little quicker than the analog signal.
Write everything to the calc_pids.txt instead of the sae_generic.txt so it doesn't get overwritten after an update.
