Semi-Open Loop Questions

[ferocity02]

So I think I got semi-open loop to work... if the short term fuel trims are anything but zero does this mean it's working? They also go straight to zero once EQR is anything but 1.0.

Something I'm confused about... So I have B3601 set to 14.17 AFR (assuming E10), and I'm commanding an EQR of 1.0 using the STFT's for trimming... This gives me an average wideband lambda of 1.012. Since my NBO2 sensors are attempting to find stoich, does this mean my fuel's stoich is actually 14.17*1.012=14.34?

Or what is the significance of lambda not being 1.0 when the STFT's are trimming to stoich?

Here are the settings I used that are different than stock:
B3801 Long Term Fuel Trim Correction: Disable
B4108 STFT Idle Enable: Disable
B4205 Closed Loop Temp Enable: All maximum (284F)
B3647 Commanded Fuel vs RPM (Normal): Set to 1.0 in area's where I want semi-open loop, which is every column 90kPa and under

Does anyone have tips on adjusting the STFT settings to improve their trimming ability? They seem to be working okay, but maybe they can be better?

My first impression is that I like semi-OL. It helped quite a bit with the light throttle and decel bucking. Everywhere else I haven't noticed a difference.

Here's a log from today, my first log with semi-OL. And a screenshot of the STFT's cycling.
