I am interested in doing the same thing (autove with lambda instead of AFR...using e85) and I cannot download the CALC.LAM_LC11 from above? Can anyone share, or explain a different way to autove with Lambda (LC-1)
Thanks!!

If serial WBO2 is an option you can use that but beware it seems to be based
off 14.7AFR you may need to change your stoich AFR to match
unless you know how to change the expression for serial PIDs.
For an analog PID you can use the standard CALC.AFR_LC11 expression
{EXT.AD1}*3)+7.35/stoich AFR

Mr. Prick, thanks for the response.
Here is my setup: V2 Flashscan and LC1 connected via serial.
I am able to log the ACTUAL Lambda from the LC1, but is there a way to log the COMMANDED lambda from the vehicle? I see commanded AFR and maybe commanded EQ Ratio, but not lambda.
In addition, I would need a BEN pid to calculate.
Is there an easier way to do it? I kinda wanted to use lambda for the same reasons as the guy above, but I just want to get this thing dialed in on the corn-gas.

For commanded Lambda:
GM.AFR/stoich
As I said the serial Lambda PID has a preset reference value
that maybe different from your OS' stoich AFR.
I started a thread asking about changing the serial expressions for this reason.
Lambda BEN would be:
Lambda/Commanded Lambda
Isn't the point of using Lambda to use it as the multiplier or do I have that wrong?

From my understanding, Lambda is Lambda. That is what the LC1 actually reads, and anything else is a calculation of Lambda. I think I may be able to get it figured out now. Gotta brush up on my calc pid skillz now, lol.

I thought 1.00Lambda = 1.00EQ which can be user defined. {B3601}
I have seen Lambda advertised anywhere between 14.6AFR-14.7AFR,
therefore I thought it was a set value.
I was recently told otherwise.
Maybe I still don't understand, if not then disregard what I said.

I changed my stoich AFR in the tune to 9.7:1 (E85)
However, the LC1 reads lambda and is programmed for whatever fuel you are using. No matter what it is programmed for, and no matter what fuel you're using, lambda will always read correctly.
