Total NEWB trying to get a better idle

[Xlexustech]

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.

[gtstorey]

Add tune and details of what you are working on.

[Cringer]

what gtstorey said and the list of mods you have on the engine.

[Cringer]

sure sorry.. tune file say z06 corvvette becasue thats the ECM. However this is a 67 camaro, ls3 GMPP crate motor 495 HP variant. 6 speed manual CAI , long tube headers.
Here is the original TUNE file

Original tune from the Z06 or GMPP? What about the actusl tune the log file was made against?

[gtstorey]

Always make sure to include the tune that produces a log together. The whole idea behind tuning is to make adjustments to the tune based upon the log and then see how it reacts to changes.

Sorry attached in the fie was working on. this is the file the LOG was generated using.

Detail. I purchased a standalone harness from PCI and a computer. They included in that a base tune. I gave them my details.
. The ECM provided by PCI has the VIN of as 2009 Zo6. Its 'tuned for a GMPP crate engine LS3/480 the 495 hp version.
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

[Xlexustech]

Bump .. ws hoping to make some improments this weekend. Any help greatly appreciated.

[Cringer]

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.

Probably just needs VVE and MAF dialed in. Add PIDs like Cringer said.

[Xlexustech]

Pulled down DTC codes. cleared them. Flashed the File provided by Cringe. Started logged Idle from warm up to 190 degrees with some off idle (2-3K) windows with no load>
Completed Logging, rechecked DTC's none found.

See attached logs and DTC details

Thank you so much for the support.. I will defiantly pay if forward.

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.

[LS ROB]

Are you able to drive the car yet? If so, add those channels and get a long log 25mins or so of regular casual driving and post it up.

I have driven it but bot too far. I cant drive it agin until the weekend but I will then .

[LS ROB]

What do you have for exhaust? Is it open headers right now? If so, no real use of tuning until the exhaust system is complete or at least ran on back to the axles.

Full 3 inch exhaust with mufflers and tailpipes

Awesome! Get that log and post it up!

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.

[LS ROB]

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.
