Had to do one more post to make it to 100 and see what the avatar says now .
{B4206} must be new to the 7.5.1 update ?

 

Nope, been around for years now...

 

Something else I just found was B4108 -STFT idle trims, this is also enabled in my tune. After disabling the regular STFT I got my VE table pretty much dialed in except in the idle areas. I am going to try disabling this parameter tomorrow and doing some logging and see how it works out.


Well that was the only thing I changed from my previous SD Tune and instead of my BEN being 1.03-1.05 pretty much every log it went to .95 then after the 3rd run it was at 1.00-1.01.....

 

Really , had not someone get this included in the tutorial ?
I mean SD is reached when you fail the MAF {P0101 , 02 ,03 } and you disable the STFTs {B4205} by temp , a lot of people have messed up tunes out there , y'all may single handedly make a lot of people have to AutoVE re-tune their cars .
Man this tutorial has been out since 03 and no one has caught this , man what a find .
I tune mainly with COS3 , so do not see this table any , man again one heck of a find there .
Oh the small "c" means corrected in COS3 , not needed anymore they are included in the new updated files .

 

I commented about it almost two years ago on the EFILive forum.

What you have to remember is that all of the tutorials you see were created by community members, not the guys that develop the software. Things can be overlooked as a result. If you find that something is inaccurate, then send a PM to the author, TA_Quickness in this case.

 

I know that you have to persist and make a strong case as to why it may need to be added .
I can see the description of the table states that it puts the PCM in Speed Density , so why not use it , unless it is redundant to other tables that do the same .
Did some looking on EFILive site and saw where someone else "vetpet" asked TA_quickness to include that table into the tutorial {B4206} , but must have gotten lost or forgotten .
BlackGMC contact TA_Quickness and ask him to include it in the next updated tutorial , or start a post on EFILive's site just on the topic of {B4206} and its effects on AutoVE .

 

So, since you cannot disable B4206 in a Custom OS, you must not have any cells in B3647 set to stoich(1.0 EQ/14.63 AFR) during AutoVE, correct?

 

I have posted a thread on EFI Live, but I will PM TA_Quickness.

No (1.00-14.63) , that would put you into Semi-Closed Loop mode with COS3 , and cause O2s to work at idle , just as BlackGMC is seeing , not really STFT just using O2s to fuel at idle .
Bad for AutoVEing , seems you want as little influence on the fueling side when AutoVEing .
Seems COS this table is disabled and hidden so to always be SD .

 

Need to change those table pics in the tutotial too. Haven't looked at the tutorial in a long time. But it shows B3647 setup with values of 14.63/1.0 for AutoVE. Don't recall if it was always that way or not.
