Getting Scanner to read Lambda

[fxracer20v]

Hey guys. My brain hurts a little and need help. I have a feeling I am just overlooking something. I want to view my LM-2 as lambda on the scanner. It is going into my Ext.1 and is working properly when I choose WB02-LC11. I just cant seem to figure out the custom PID portion of everything. I want to log in lambda because now that I changed Stoich AFR in the tune to 14.27 for the wonderful E10 we have, now my BEN factor is way off cause commanded AFR is 14.27 which = 1 lambda. I am a fan of tuning with lambda vs AFR.

And then my next question, this system will only show me Commanded EQ or Commanded AFR, no Commanded Lambda. So what do I need to do, or what formula/custom PID do I need to convert either the commanded AFR or the commanded EQ over to lambda so I can use a BEN Factor for tuning.

this is a 05 5.3l

Any help would be greatly appreciated! Thanks Guys

How is your LM-2 hooked up? I presume via serial, since you refer to EXT.

In this case, log Commanded EQRatio (GM.EQRATIO) and Wideband Lambda (EXT.W02LAM1), then use the BEN factor CALC.W02BEN.

Serial comms from wideband would allow you to log in Lambda.

PCM commands in EQR.

Both are independent of stoich AFR.



( to run correctly, you would still need to set B3601 to the stoich of the fuel you're running )
