What would cause my idle to drop off at start up? What tables control this? My engine almost dies at start up. I would like for my idle to drop no less than the 750 programmed into the file.

Have you tuned your ETC Idle Angle table? If you have one, I can't see the tune on this computer.
Made a huge difference in my idle after changing the intake and TB.
This table is stock. What values would I change to keep it from closing too much? Increase the 450, 590?
create a scanner graph like the editor table logging throttle angle against lb/min
do a completely cold start (overnight cold) and fire it up, and don't touch the gas or anything at all, AC off, etc log it while you let it idle in place until it is completely warm and idling at the commanded RPM with the cold start procedure completely finished.
paste the angles into the editor table.
make sure your other items are in place like MAF/VE and injector data, otherwise, garbage in / garbage out.....
Thanks Higgs! I'll see if I can give that a try.
Also, make sure if you have tables for idle per vct angle that you adjusted those accordingly to how you adjusted your regular idle rpm field. I will look at the tune this evening or in the AM.
Here's a short log I ran. Is this what you are looking for?
The engine died on the first start up. I had to give it throttle to get it running.
I wont be able to see it until the am. What are the results? Screenshot works great. ;-)
Did it have any effect? Does it idle good or die after you have been driving it around? Is it only on cold start it dies or all starts?
Third pid mass air flow is airmass in lb/min
Fuel trims are pulling all kinds of fuel, very rich. Tune the maf, when you first start it it's probably very rich and dying.
Yes, I saw how negative the trims were. I'll go in and fix that first. Like you say maybe the problem. Thanks Higgs!
