Open Loop vs Closed Loop Tuning
 

Copying my post from the Skeese informational Open loop vs Closed loop tuning section in hopes to reach more help, thanks

I've started tuning my car and its kind of fun after you learn the basics and the why behind fueling and timing. Just recently did a log and drive in open loop mode and when I play back the log tracing afr's, when I highlight a cell, it still shows a quick trim value, which I would think indicates that the car was still running in closed loop fueling. Did I not set the ECU to open loop, I changed the closed loop drop down to open loop before I started logging. Is this the correct way to change the car to run in open loop?

Furthermore, I have fuel cut activated and I think that's why I see a lot of lean conditions in the table, mostly in high vacuum areas. I'll have to either turn fuel cut off in decel or when logging jump to neutral during deceleration if I don't want to skew those cells for tuning.

Anyway, slowly learning and staying out of boost for now
