Changing BEN map from AFR to ?

[ssvolvo]

Hi guys,

I'm logging with an LM-1 to adjust my VE B0200 table:LS2.
Just starting so please bear with me. My BEN map is in air/fuel AFR units so when I "Paste and Multiply with Labels" to my VE map I have a map that resembles Victoria Falls (really)! Looks like I need to convert this AFR to Lambda or EQ? Please assist me in doing this. I've spent HOURS on this and I'm sure it's a quick fix as I know my idle is darn close and doesn't need 15.1 times more fuel!!


Thanks again, John

you need to select the BEN PID for your WBO2,
and change your map to read that PID in the map properties. (data)

Mr P!

Can you look at my log and PID selection? I thought I had that down pat. Thanks, John

I had to edit my sae_generic.txt file like this:

# Innovate LM-1 WBO2
# ========================
*CLC-00-928
V 0.0 5.0 .1 "{EXT.AD1}"
AFR 10.0 30.0 .1 "{EXT.AD1}*10"
*CLC-00-929
factor 0.0 2.0 .1 "{CALC.AFR_LM11.AFR}/{GM.AFR_B}"
*CLC-00-930
V 0.0 5.0 .1 "{EXT.AD2}"
AFR 10.0 30.0 .1 "{EXT.AD2}*10"
*CLC-00-931
factor 0.0 2.0 .1 "{CALC.AFR_LM12.AFR}/{GM.AFR_B}"

Hope that helps,
Al

OMG! Thanks Al! I blew 5 hours on something this trivial. Why? Oh well, whatever. Worked like a charm.





THANKS!!!!!John

Glad to be of help. I downloaded your log file and tested, it had the same problem that I encountered. I thought the link had been fixed though.

It's at least usable. Now I'm trying to figure out why the LC-1 and Lc-2 don't have the same settings in the sae-generic txt file. Seems they both are setup the same way in the LM programer software.

I guess I'm arriving at this because now my BEN at idle is 2. My map for the BEN is averaging over "2" across the board, yet my WBO says it's no where near that lean. My wide band says around 15-1 A/F ratio. I wouldn't think that would work out to be a "2".
I have a 5 gas to verify my wide band. Also a labscope on the output of the LM-1 to make sure the scan tool reads the same voltage. IT DOES. Still when I paste and multiply the fuel number goes from 37 to 115. Kind of rich don't you think. I know it needs just a touch of fuel right at that cell; not 3 times as much.

I'm thinking I need to change the numbers in the sae_generic file but not sure where. Have tried several things but to no avail.

I'm catching on slowly and DO appreciate the help. Thanks again, John

re you sure you are looking at average ben factor and not cell count ?

[joecar]

Don't edit sae_generic.txt... instead, create new calc pids in calc_pids.txt.

See post #27 in this thread: showthread.php?t=132

Program your LC-1 for 0V==11AFR and 5V==16AFR
and use the calc_pids.txt from post #27.

Cell count made my VE look like victoria falls.
