Noticed yesterday that the "ECU Configuration" screen had the feedback control in OPEN loop. I switched it to Closed loop so that I could attempt to fine tune it via the A/F guage on the bottom RH corner of the base fuel map.

In doing so..... part throttle driving now sucks, and it is way rich at WOT. Shouldn't Closed loop improve my part throttle driveability? I'm getting ready to switch back to open loop and see what happens. As far as being rich at WOT......it is my understanding that under full throttle it will always be in Open loop, so I guess I also need to look at my base fuel map as well.

TIA.
