Cam Tuning Questions
I can send you some tables but in all honesty the main things used to get that idle were adjusting the throttle blade to dial in IAC counts while dialing in the VE table in SD. I started with a converted 2002 .bin file.

Yes, but have to make changes to the VE table as you go until you can hit desired A/F with IAC counts between 60-80. When it falls too rich it really lopes at 800 almost shutting off. I shot for 14.7 with 60-80 counts. Transition is great and no hanging idle problems. Just reset the TPS after each change.
My **** idle right at 14.7 now and stays in closed loop finally. I finally dropped the idle down to 850 to and it lopes nicely. I have had nothing but good results so far with the exception of a super rich AFR at WOT(10-12AFR), thats an easy fix though for when I get motivated to drive and log a little.

ok swapped puters. Car warm started no problems at all.. Went for a drive and it had idle hang. tuner adjusted for that. WARM start was gone AGAIN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! MY CAR ONYL WANTS AIR on start up.. WTF!
anyways got some prgress though.... no more hesitation any more.. well, ver very faint, bucking is better
So my only real problem is WARM start
b4 you all ask, i saw the idle park table and all other tables. the car is maxed at 64 g/cyl... the needs 128+ steps for a perfect warm start. 121 and below = no warm start. And i had a stock air table in there that did nothing. the car is fvcking bull ****. the tuner and i did everyhting AGAIN.... The car only wants air on startup, after it gets air, the IAC is pratically at nothing.... Go figure. All in all i am happy now gott a sacrfice somrting

I'm telling you....there's a table in the PCM that adds extra airflow for post-startup idle. In EFILive, it's called Startup Friction Airflow Correction. If you increase that table 4~5 grams/second, you'll have enough airflow for warm starts. IDK why your tuner doesn't do that.

How different is EFI Live to HPT?? B/C trust me, the suggestions that you are all making to me, we are doing them all. The have no affect on my warm start at all....
