E40 LS2 c6 cam+ idle tuning

Hey everyone, first thanks in advance for any help.
I have tuned a few different cars and know the E78/E38 pretty well. This E40 on my own personal C6 is frustrating me a tad.

Ive gone through hundreds of pages in various books, threads etc and it appears that within EfiLive I do not have access to the tables that the HPT guys do?
I am hoping that I may be wrong as I am invested in V2 on several cars including my 16 LML Denali.

Specifically what I want to do is control or specify the commanded closed loop idle mixture?
Does anyone who is well versed in the E40 have a procedure lined out for how to setup the idle airflow?

• Changes I have made to Minimum Idle Airflow (B1829) seem to have no effect on actual idle.
• Is cheating by modifying (B1650) Max ETC Area the only way to "trick it" into more idle throttle? Assuming it does not barf and throw codes....
• What do the (B1651-1652) Max Idle Area 1 & 2 do?

Thanks again,

Yikes, nada.
One of the guys on the HPT board wrote a full E40 idle tuning guide. Was curious if the same might exist here.

Thanks again if anyone can chime in.

opcode, thanks that thread does have some helpful info even though its the E38 vs my E40 :thankyou2:

The 2 tables I do not have (that im used to in the E38) is B1843-1845 aka Idle Integral Step Size and Proportional size... for control of the PID loop. What I was wondering is if anyone here knew a "trick" or substitution to use in the E40 to accomplish the same thing.
