LM-1 Programming & Settings

[5.7ute]

Ok, sounds good, I'm going to try it. Now for a dumbass question, but I want to be sure ... the EXT.AD1 pid in EFILive corresponds to Analog Output 1 on the LM-1, correct?

It depends on which input slot on the flashcan you have wired up the wideband.
Put the red wire in the "E" slot to make analog 1 in the wideband read as EXT.AD1 in the scan tool. Analog 2 (white wire) goes in "C" The earth in"D".
Program analog 1 to the lc-1 settings. Analog 2 to a flat 2.5 volts & change the generic txt expression for the LM-1 to (({EXT.AD1}-({EXT.AD2}-2.5)*3)+7.35 .
Then you are good to go.

I get your point. I've got the white wire in the "E" slot. So compared to you, I'm reversed. Analog output 2 gives me the AFR swing while 1 provides the constant.

Does this look right for the LM-1 pid, then? I'm assuming you only have to alter the EXT.AD1 pid, not the AD2 pid as well?

*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}"

What is your stoich AFR {B3601}?

[RevGTO]

what is your stoich afr {b3601}?

14.63

*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}"

No, Since EXT.AD2 is where the wideband is reporting the AFR you will need a CALC.PID like this.
*CLC-00-928
AFR 10.0 20.0 .2 "(({EXT.AD2}-({EXT.AD1}-2.5)*3)+7.35 "
EXT.AD1 being the flat 2.5 voltage.

I like 5.7ute's method of canceling out voltage offsets.

Well, I did some logging today with this setup and ended up with highly skewed results. Logged AFR's read steady at 12.9-13.0 (commanded=14.63) while AFR voltage varied between the usual 1.5 and 1.7. Somehow, I didn't do something right (no surprise). Here's how I have the LM-1 programmed attempting to follow 5.7 Ute's instructions:

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

Analog Output Two:
.996v @ 10.01AFR
1.998v @ 19.99

Here is how I have the sae_generic.txt pid for the LM-1:

*CLC-00-928
V 0.0 5.0 .1 "{EXT.AD1}"
AFR 10.0 20.0 .2 "(({EXT.AD2}-({EXT.AD1}-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}"

Again, I have the white wire in the "E" slot, and the red in the "C", ground in the middle.
Where did I go wrong?

RevGTO. Post the log & your generic txt file & I will have a play.

Ok, here is the sae_generic.txt file.
