anyone help with a baseline tune
2002 Stock bottom end ls1, 243 heads stage 2 TEA ported heads, 231/238 .615/618 112+3 cam, fast 92 intake, Ls2 throttle body, 1 7/8 AR headers an x pipe, corsa mufflers, 42# ls3 injector .
I'm having hell with it getting to startup without using the pedal after startup I can get it to idle with a little throttle play but still not even 50% right yet.

These are very very broad strokes of the tuning brush, but given that you sound pretty new I'll generalize. A lot. Make sure you are in Imperial format, so Tools -> Options -> Imperial.
Make sure you have your injector data correct. The Flow Rate vs KPA is the most important, but the more info you get correct the better.
Flow Rate vs KPA
Offset vs Volts vs VAC
Short Pulse Adder
After you copy and paste those into your injector tables, change your format back to Metric from Imperial and input the following table into your Idle -> Airflow -> Base Running Airflow -> Idle Airflow.
Then go to Airflow -> General -> Main VE -> Primary
If it's an auto you'll need to raise your idle to at least 800rpm, but this should get you started.
Make sure you have your injector data correct. The Flow Rate vs KPA is the most important, but the more info you get correct the better.

I've got it running the issue I'm having is with the idle hanging on decelI can't get that issue cleared up. I've been tuning for awhile just have never messed with going to a larger size throttle body with a dbw setup an it has me head scratching. Sorry I should have been more clear an not made it look like I was looming for a complete tune but more of a baseline for the throttle body.

To fix a hanging idle in gear---1st see if it happens at ANY MPH or only in a specific MPH range-- and in all the gears or only 1 or 2
That way you an make specific changes only where needed
The most common area is in 1st gear from 0 -6 MPH---
To correct a hanging idle you need to ADD more % to the
"throttle follower decay rate in gear " Leave the DELAY rate alone
PS: If any of the table boxes have a "0" entered -- input the last table number that has a number so none of the boxes have a "0"
( you can't add a % to "0" )
ALSO : On some large cammed engines you should also delete the DFCO program to eliminate the fuel cut-off on decal which will cause it to stumble or die at a stop
