But yes on that the lambda output from the LC-1 is stoich for whatever fuel you are running. It is your job to know the stoich AFR of your fuel and command it appropriately.

If I am reading between the lines correctly, then the LC-1 wideband (when reading lambda) can tell when the car is running stoich, regardless of fuel/ethanol percentage?
Lets say I use the LC-1 in a car that has a good tune for gasoline, it will read 1.0 lambda at stoich (14.7). Then I take the LC-1 out and install it in a car that has a good tune for E85, the sensor will read 1.0 lambda at stoich (9.0)?

Yes, correct.


You set B3601 to tell the PCM what fuel the engine is running on.

From the other thread, you can see that Lambda is regardless of stoich AFR... i.e. stoich is Lambda 1.00 for any/all fuels.

I've got a question about the filter being applied to the map. Specifically this one:

{EXT.WO2LAM1.lambda} is greater than 1.06 Lambda

Why are the values over 1.06 being filtered out of the data?

To filter out DFCO (deceleration fuel cut off).

Well, I'm seeing some pretty lean figures in my map from my last log, so won't this filter out those cells as well? Since switching to E10 gasoline, it's made some rather lean cells up in the higher RPM cells. If you look at the latest log I have in my "Sanity check" thread, you will likely see what I am talking about. So do I really want that data filtered out?

BTW, I believe I've got DFCO disabled anyway....

Ok, I'll look at it...

Where exactly...?

I have one Question. I´m using V1 and Lc WB and is working great. But If I want to test an AEM 31400 WB, What changes I have to made in calc. pids, I look over the site I can´t find any info.
