LM-1 Programming & Settings

[5.7ute]

0.06 volts on both channels is an error in the connections.
I agree with the CALC.PIDS not being overwritten and being a better option for the changes. We will get to this once we get everything else sorted.

Yep, the connection must have been a problem on that log. Did another one and the LM-1 voltage range was 2.2-3.2, corresponding to LM-1 AFRs of 21.82-31.40.

So I'm assuming a factor would need to be derived for the calculated pid that would translate these numbers into accurate AFRs?

Or maybe I was best off with my original settings that I had with 7.3.3:

Analog Output One:
0.000v = 10.01
4.996v = 19.99

Analog Output Two:
1.001v = 10.00
2.002v = 20.01

No. Just post that log so I can change the expression in your generic txt file to the new settings.

[5.7ute]

Actually, just use this.

[RevGTO]

Thanks, will do. BTW, did you make any other changes besides the CLC-00-928 second line? I've been changing that in my edits rather than copy/pasting the entire sae_generic file.

Fantastic! Finally found the winning formula! Got a couple of logs done and my AFR's now read like my meter instead of too lean. Now I can move forward to perfecting my Calc.VE tune. Thanks so much 5.7 Ute for your patient assistance!

Good job...

Here's a brief log file with a lot of steady throttle.

For anyone else who's using V1 with LM-1, here's the programming that got my AFR's accurate, meter compared with logged data. This is with the white wire in the "E" slot; if you have the red wire in "E", programming for analog outputs 1&2 will be reversed.

Analog Output One:
2.501v @ 10.01AFR
2.501v @ 19.99AFR

Analog Output Two:
0.88333v @10:1 AFR
4.21667v @20:1 AFR

LM-1 sae_generic.txt pid:
*CLC-00-928
V 0.0 5.0 .1 "{EXT.AD1}"
AFR 10.0 20.0 .2 "(({EXT.AD1}-({EXT.AD2}-2.5))*3)+7.35 "
*CLC-00-929
factor 0.0 2.0 .2 "{CALC.AFR_LM11.AFR}/{GM.AFR}"
*CLC-00-930
V 0.0 5.0 .1 "{EXT.AD2}"
AFR 10.0 20.0 .2 "{EXT.AD2}*10"
*CLC-00-931
factor 0.0 2.0 .2 "{CALC.AFR_LM12.AFR}/{GM.AFR}"

Thanks again to 5.7 Ute!
