start up tune advice I have looked at a few videos on youtube and some web searching. I came across a video (LSXTUNER) and it was suggested for a cam swap start up tune to start by multiplying .75 in the VE table at the 400-1200 rpm range up to 70 kpa… I tried this multiple times and the car still starts and shuts off. the idle is set at 1050 rpm. I also tried the adjusting cranking VE using the same method. I added 2 g/s across the chart to the Base running airflow/ idle airflow.. I also changed the cylinder volume because of the ne CID of the built engine.
the engine is a 6.0 bored .030 with a 3.900 stroke. 397.97 CID and 6.5L. cam is a tick stage 2 LS2 cam 231/236
please any help is greatly appreciated!
I'm a 46 yr old noobe at tuning.. be gentle with the comments lol. I know what I did is not good

Well... can someone at least tell me if I am going the right direction.. by multiply. .75 in the VE table, it caused the number to decrease. lower the mean more air? Cuz it doesn't seem it would be that way.

"The maximum allowed value in any cell is 127.5. To increase fuel make the values larger, to decrease fuel make the values smaller."
Found this^^
I'm guessing there is other tables I'll need to address

What ECM are you using? Does it have two VE tables (primary & secondary) if so the computer looks at the secondary table first. Those VE numbers in your tune look really low. You may also want to lower the timing (high/low octane) a few degrees after you get running then work your way up. What injectors are you running, have good data?
Here is the mail order tune file I started with from a well respected tuner. It fired right up and idled fine but I had to do some fine adjusting. The injector data will not be useful to you. If you open this in the comparison file tab you can see the big differences in the VE tables and also the MAF calibration. Engine is a GEN III 6.0 with a similar camshaft 228/230 585" 585" 112*

Have you looked through the injector data sticky for the bosch injectors?
Injector Data
Try copying over both the VE tables, MAF calibration, Idle base running airflow, Idle base set point.
Under "spark advance" copy both the high & low octane tables and also both the Idle Spark Advance tables (in park/in drive)
When you click in the empty square next to the column axis (top left) it will highlight the complete table then simply right click to copy that table. Do the same for the table you're wanting to paste into.
The tune I posted is a P01 also.
Hopefully it will able you to get running enough so you can start logging data and applying that to your tune.

couldn't wait.. copy and paste what you suggested … STARTED AND IDLE! thanks again!!! I need to get my wideband installed. smells little rich. Can't drive it yet, car sitting on jack stands right now, i'm waiting for my Bilstein to show up.
went out to try again and it wouldn't stay running..

Open the Math Parameters Manager to view what needs to be logged.
Click Tools (top menu) > Math Parameters > Fuel Flow > Injector Duty Cycle.
On the bottom right you'll see the two channels you'll need to add "Injector Pulse Width & Engine Speed RPM
Close the math manager.
In the "Channels" add channel > Type "Injector" in the text filter > Add both bank 1 & 2 Injector Pulse Width to the channel list.
Add Channel > Type in the text filter "RPM" > add Engine RPM (if you are not already logging the RPM parameter) to the channel list.
Save the new channel config... if not saved the injector duty cycle will not show.

To see the Injector Duty Cycle in the "Chart vs Time"
Right Click on the chart > Charts Layout > Click "Add Series" > Click "Parameter to insert or change" > Maths > Fuel Flow > Injector Duty Cycle

Looking at your channel PID's in your scan you're not logging the needed parameters. When I have time I'll upload some config files for the scanner. You're going to need that Wideband to move forward. I recommend the AEM X Series.
Goat Rope Garage (Kyle) has some really good tutorials. Every Thursday at 8PM he has a live Youtube Q&A session and answers questions much better than I can. If you start with tuning the MAF by watching his MAF scaling video things may fall into place. Subscribe to his youtube channel for some really good info. He also has a Patron for like $15 where he looks at your scan files and recommends any changes.

Sorry for delayed response. Thanks everyone for the help! So far I've been able to get things figured out as far as what I want to data log. I'm also getting some histograms set up . Waiting for the freaking bilstein struts to show up (supposedly this week) so I can attempt to start tuning VE tables.. well probably should try and drive it around some first.
I noticed the LTFT , STFT have been disable prior to me.. whats everyone opinion on this?
I have watched some of goat roper as well as HP Academy. Also read a few write ups on VE tuning using LTFT,STFT. I'll have to reread once the time comes to tuning.. if I remember correctly the MAF needs disable and a few other things to keep it in.... CL.. LOL need to read it again.
Thanks for all the advice! I keep a open mind tho all that is given! So thank you!

You'll want a wideband to tune the VE tables safely. You can use the narrow bands but I'd advise against it. The MAF is really easy to tune (if you're running one) and only takes a few data logs to get a nice MAF curve. The VE tables take quite a lot of data logging to get dialed in close enough for the narrow bands to trim the fuel the rest of the way.

Here are some good links to help with idle tuning.
Tip:
ChopperDoc on YouTube has a series of tuning videos (if you haven't added them to your tuning links). Both are 'Learn by Example" tutorials.

Dan Maslic has a series of 5 idle tuning videos that show how to set up or correct idle issues. The complete digital file is inexpensive with 5 sample guides for various sample cars: turbo, heads/cam etc.

IMO - get the Digital File from Dan Maslic. It has tuning samples with both flavors - HPtuners and EFIlive.
