No option for 2 bar SD on my 2010 silverado?

[02Ls1]

I was looking to make my truck SD mode and I was searching around how to log the VE, if I can use the same configuration scanner that I use to log the 0411 pcm's.

Searching around I notice that there are several Operation System that are allowed to become 2 bar map - Speed Density, so I got my file to take a look at it and it don't have an option to choose the 2 bar SD. I looked for another file with different OS and it does have a option to choose the 2 bar.
What can I do or I would have to stick with MAF?

Truck is a 2010 5.3, here are some screenshots and the difference of the both OS mine its the one saying not available on all.

Use the virtual VE editor in the beta and you can tune "boost" areas the same as you tune regular areas. No need for a custom OS anymore.

I finally found some time to play with this.......I'm assuming you just add values to the MAP axis in order to start editing into the boost areas. In which case it auto generates the VE as you change the AXIS. I tried it, by adding 105-135 in 5's and it seemed to work, and if that's all it takes.....freaking awesome!!!!

@ Bill, are the added VE cells calculated from the coefficients, or are they predicted by rate of change? The reason i ask is you'll see in the image i posted of the VVE, it has quite the cliff between 3200 and 3400 rpms and only at the kpa values i added.

It doesn't seem to save changes to the MAP axis when you close/re-open the editor, so it's probably just easier to use the template already in there for 0-210kpa. I don't remember exactly what it's labeled, but it's under the box where you can put in MAP values

Pretty sure it best fits to the data it has available. It won't be perfectly smooth and pretty like a regular VE table from what we've seen so far, but it does appear to work quite well overall

Will I need a map sensor? I bought the zr1 map sensor.
It's there a way how to tune this virtual VE? I will try it I was trying to go 2 bar like the 0411 pcm's and tune the VE but this is new and haven't try it nor the Virtual VE.

Yeah you'll need a boost capable map sensor to make use of anything above about 105kpa. Install it and update the map sensor settings

Ok well I have the zr1 map sensor the baro red one.
What configuration I can use to log it? I feel lost here but I would start messing with it to get the hang of it.
That's why I want it just go 2 bar speed density since Ive done it on the 0411 pcm's.

Working with virtual ve isn't much different anymore. Just hit calculate coefficients after you make your changes and it takes care of that automatically.

You'll need to setup a histogram with break points that line up with whatever ones you're using in the VVE editor.

What wideband are you using?

[02Ls1]

I'm using the ngk afx wideband.
I would need to check on setting up the scanner.
