Equivalence Ratio (EQ) Discussion

Here are some screenshots.

Basically add your input to channel list

Transform

Under EQ ratio find your wideband

Should look like this

Now back in the channels list if you right click on your WB you can change the units to be based on some common stoich values. Say, 14.7

To use this in a chart, add the wideband like normal.. the EQ ratio one

Under units you have the same options for unit you did earlier. Pick whatever you want, 14.7 obviously is common one

You can also add another parameter for lambda if you want. And you should end up with something like this. AFR and lambda, side by side off of one input.

Hi,

Sorry to bring this up again but I do have some questions please;

I have Daytona vi widebad sensors. and under EQ ratio in the transform section there is a daytona sensor wego. Is this the same sensor?

Also, If it is the same one do I still need to do the offset correction? and can I use the same spread sheet but instead of putting 10.3 and 19.5 I would put the lambda values ( 10.3/14.67 and 19.5/14.69)?

or there is another way to do it?

Thanks

Just use what's already included and see what you get. If it matches the gauge then you're golden

Hi guys i know this is an old tread but im curious to know how all this data is used to create histograms if i use say 30-4041 and transform to lambda in the channel selection what do i use as a parameter in the row and column of the histogram sorry new to this and trying to understand thank you great info. here

u can copy the column/row axis to mimic the table in editor u want to adjust, then setup the graph up to show what u want use "parameter" say lambda error then u know at each point what the error is to adjust the VE, VVE or MAF ect

E40 will report the correct EQ ratio unit in tomorrows beta.

If you know of any other controllers that report EQ Ratio Commanded (SAE) as phi and not lambda, let me know and we can fix it.

Hi I just figured out that the E39a PCM used on the LFX does this same thing. As far as I can see, there is no way to change the tables. It would really be a big help if somebody can implement a patch for this!
