This is meant to serve as a basic how-to for setting up an AFR or Lambda ERROR graph (histogram) for vehicles with regular VE tables (i.e. not virtual VE).
This assumes you already have your wideband working properly....
---------------------------------
First go to the Graphs tab. If you don't have a Graphs tab, go to layout, add to layout, graph. Right click in the graph, select graph layout
We want to add a new table.. select the graph icon with the + on it and select Add Table
New blank graph is added
Click on "click to insert or change" beside parameter at the top. Go down to the Lambda & AFR list and find EQ Ratio error OR AFR ERROR. I'm not 100% sure on this one but I THINK it depends on what units your wideband is setup to read. Mine is setup to lambda and the EQ Ratio Error parameter works. AFR error does not. If one doesn't work, try the other....
Double click on EQ ratio error or AFR error
Back to the layout editor, click "click to insert or change" beside parameter for the column axis.
Couple steps at once here.. type manifold absolute in the text box at the top of the parameter selector, hit the gear icon with green check mark (filters out stuff you can't use) and double cilck on whatever MAP pressure parameter is left that you can use..
You'll probably get a box about using a generic sensor. Generic sensors are good. Hit yes
Alright, now we need to match the labels up with the labels in your tune. Go to VCM Editor and open your tune. Open the primary VE table. Right click inside it, go to column axis and click on copy labels
Paste these into the "values" section for the column axis
Next is the row axis.. very similiar process. Click on "click to insert or change" in the row axis section, type in engine rpm, hit the gear icon, double click on parameter that is left. If you get a generic sensor box hit yes.
Here's what it should look like at this point
Now you need the labels for the row axis. GO back to VCM editor and go to your primary VE table. Right click, Row Axis, Copy labels
Back to Scanner.. paste these values into the "Values" section for Row Axis
Ta-da
Next I usually setup some colors for different values to make it easy to see, maybe add some minimum cells required while you're at it. You can set this to 0 at first if you want then change it later after you make sure everything is working
And there you go.. you have a working wideband Error graph/histogram
BUT... what about boost you say? I didn't forget that part. There are two ways to do this. You can either have a "regular VE" chart and a "boost VE" chart or you can do one big one that includes both.
Go back to layout editor (right click in a graph, click layout editor). Go to the Graph you just created. click on the graph button with the "=" sign on it. That will clone your current graph.. Rename one of them to something like "WB BOOST VE ERROR"
Go back to VCM editor.. this time open up the BOOST VE table. Right click, column axis, copy labels
Back to Scanner..d elete out the "Values" for the column axis section. Paste the boost VE table values in here..
Now you have a regular and boost VE WB error chart. If you want to make one BIG chart instead of two small ones.. you can do that too
Go to the "boost" VE chart you just made. Select the "values" for in the column section (skip the first value). Right click and hit copy
You can either make a copy of your "regular" WB VE Error" graph or you can just change the original one. Here I used a copy. Go to the Column axis section and paste the boost VE table values in after the regular ones. You should end up with something like this:
And ta-da here's what you end up with. Looks like I'm going a little lean, oops! (side note: The really negative numbers are mainly from deceleration and DFCO, those can be filtered out but we're not going into that right now.)
Enjoy!
