Do I need to disable or enable parameter B4206 during AutoVE tuning?

B4206 disables the STFT correction, from what I understand.

 

Disable if you have any point in table B3605 = 1.0 (stoich)

 

Yep all my lower MAP cells are set to stoich, so would this explain the difficulties I have been having while trying to tune my truck?

Why was this not in the tutorial...

 

Well just incase anyone wants to know disabling the above mentioned parameter helped out a ton last night. The tutorial mentions nothing about disableing it . So the last 4 AutoVE sessions with about 5 logs apiece are all crap!!!! Last night I started over from scratch and in 3 logs I was done!!!!!!! I was even able to tune the MAF last night and the truck is running great!!!! My WB is not freaking out anymore, so that is a good thing, it reads nice and steady. No wonder I was getting like 12mpg on a basically stock truck my VE table was so far out of whack..... I really wish that damn tutorial mentioned this parameter in the first place!!!

 

Nice catch , what year is your tuck again ?
Nice job on the metal intake cover as well !

 

Thanks, it is an 04.

 

Thanks , will look for that table when doing a 04 , good info .

 

It's not just 04s. All stock OSs have that table. Custom OS's have hid that table to force it to "enable" to allow semi-closed loop.

 

Yep I saw it on a 5.7 vette and an 01 silverado.. That is why I asked why it is not in the tutorial.... But I have read that 05s don't have it.

 

Working on an 05 right now and it does have it.
06s have it.
07s have it.
