COS5 question on STFT's

[onfire]

After I modified the tune per the EFI Live COS Tutorial, I can't get the STFT's to move off zero when I log. The tutorial says when Closed Loop is Disabled and STFT is disabled, B3647 is dominant and a semi loop state is enabled with o2 feedback through stft's.

Is there a special pid other than stft bank 1 and 2?

What's your EQ or commanded AFR?

14.6 in B3647 0 to 90kPa . Also 14.6 in the stoi table.

Do you have to enable B4108 or B4205? I also have B3801 disabled and B4101 set to 80kph. Just not sure of the mix to get "semi closed-loop".

IIRC, you will need to adjust B4205 back to stock to enable STFT's. You might want to wait for someone else to chime in as I've been !nb for some time now.

B4108 relates to idle so you can enable that if you want...

Strictly speaking to enter Semi-Open Loop mode you simply need to have the intended cells in the B3647 table set to the same value as B3601. If your tune doesn't have the B3601 table then it is hardcoded to 14.63:1. If you use dsplay units of EQ Ratio then just set the cells to a value of 1.00.

B3601 is set to 14.6

Cells in B3647 is set to 1.0 (In lambda)

But, STFT's are not logging with B4108,B4205 and B3801 disabled.

Thanks for the tips, I'll play more tomorrow....this COS5 stuff is addictive.

To get "semi open loop" on my car:

B3647 must be 1.0 in all lower cells.(less than 80kPa)

B4108 must be enabled.

B4205 must be enabled.

Keep the LTFT disabled.

B3601 = 14.6

Now the STFT's log on FS.
