Working through the WIKI / how to on Setting idle. I made all the Step 1 adjustments as described.
Here is a log file form a cold start. Lookong for feedback if it looks like I am off track or not.
any help appreciated.
Edit: Log file and tune file + parameter files attached altogether below.
Add tune and details of what you are working on.
what gtstorey said and the list of mods you have on the engine.
Original tune from the Z06 or GMPP? What about the actusl tune the log file was made against?Quote:

I have little 'faith' in the starting file car runs, drives but when coming to a stop stall at idle or I have to feather the gas to keep it running
Set up. GMPP ls3 480 (495 hp) in a 67 camaro with PCI harness and oem computer out of a 2009 zo6> 373 rear, t56 magnum 6 speed. Only 1 set of 02 sensors, long tube headers, COld air intake.
condition stalls at light or stop after cruisng , hot start issue
Bump .. ws hoping to make some improments this weekend. Any help greatly appreciated.
Try this...although the one O2 sensor...are you going to fix that? You also need to start adding more relevant PIDs to your channel list.
Attachment 151612
Probably just needs VVE and MAF dialed in. Add PIDs like Cringer said.

Looks lean. Add Injector Duty %, Injector Pulse Width Bank 1 & 2, Dynamic Airflow, Volumetric Efficiency Airflow, Cylinder Airmass, Mass Airflow Frequency Sensor and Fuel Trim Cell to your channels.
OK Ill do some homework on that and add them.Quote:

Full 3 inch exhaust with mufflers and tailpipesQuote:

Hi guys just took the car for a nice 20 min cruise. got some gas start stop and a few 3/4 throttle romps.
channels added. Log file Attached. Thank you all so much for the support... reading as much as I can and watching goat rope like a lunitic...
Feedback on log greatly appreciated.
You missed Dynamic Airflow. Log that next time and no WOT pulls for now. Flash this and drive 15 min before starting log. Pretty dang lean from 1500 rpm and under, but rich above that. This should help some but got a fair amount to go to get it dialed in.
