Newbie. Installed air box, intake, mild cam, heads, headers, exhaust.
Remaining stock is the TB and MAF. CATS have been removed.
I am using EFILive FlashScan V7.
I have read thru a PCM tuning doc I found on LS1racer.com.
I have got a bit of idle surging.
Adjusted TB set screw. Unplugged TP sensor to reset it.

IACDES_B (desired idle air control air flow) was significantly less than DYNAIR (dynamic air flow) So...
Adjusted IAC effective area table to the right. Which definately helped idle.

Idle surging is nearly all gone but other issues appear to have been created.

LTFTs are positive approx. +4.
Warm idle AFR is often going into 15s.
WOT AFR is at 13.5

Before TB set screw adjustment I had lots of idle surging. But.
LTFTs are slightly negative or 0
Warm idle AFR was in the 14s.
WOT AFR is at 12.5

Questions:
1. PCM doc mentioned lowering base proportional. Where is that at in EFILive?

2. PCM doc mentioned adjusting running airflow. Where is that at in EFILive?

3. How do I fix the positive LTFTs. By adjusting the MAF table?

4. PCM doc mentioned adjusting adaptive idle limits and/or air flow. Where is that at in EFILive?

5. PCM doc mentioned adjusting idle airflow. Where is that at in EFILive?

6. Is there any other table I need to tweek to fix the issues that have poped up?
