{B3647} Open loop AFR

[GMPX]

Man even if sends it to me in a email, im not ready to copy and paste again. Going through all the cal is not fun copy and past, copy and paste :oops:

I can't generate the cal files, since they were posted I have already changed and added a few things. Please Email Paul, he will have that cal set to suit what you need.

Not trying to wipe my hands of it, but it's not something I can do.

Cheers,
Ross

Ross did everything that was instructed and watched how stft worked when in 14.68afr. I finally understood what semi open loop means and also it seems it runs better in semi open loop than full close loop. Today im going to do somemore tuning with the wideband and also what are some safe lean numbers to run, i kinda of looked at lean cruise from holden but i didnt know if to follow these numbers. One thing I would like to see and I know maybe its just me but a parameter that triggers the table b3647 such as engine has to be so warm before it will follow the table.

I am running in open loop all the time. Have you tried to run in just open loop all the time? I might have to try semi open loop to see the difference.

Yea i have tried the open loop full time but what i like about semi is stft are still used such as at idel and part throttle which helps the truck run even smoother

To go into semi open loop do you just enable stft's and that is it?
Everything else stays the same as openloop all the time, right?

Follow the instruction that are posted, that will get you going. STFT are disabled i know it dont make sense but Ross has these things setup and thats what he said to do and it does work

To me it looks like if you have b3647 at 14.63 you will be in semi Open Loop. The question I HAVE is at the bottom of the page it states:
Several other STFT values may require adjustment:
b4101
b4102
b4103
b4104
b4108

Do you know if these need changing from stock?
Thanks,
Bill

Bill - Have you read this thread...especially note page 2 - GMPX's info on the custom V3 OS. ->>http://www.efilive.com/forum/viewtop...d36f3a0e222208
Good info on Semi Open/Closed Loop.
Hope this helps some.
