Looking for ideas why randomly I would get a close loop commands under wot.
It has happen to me 2 times on test drives in different rpms and gears any ideas ?

427 2.9 whipple 23x at 50 cam
It has been driving very well
There also was some tq control in lower gears

( too many pids, this is reducing the sampling rate from 40 Hz to 10 Hz )


That log does not show CL, the HO2Sx1 voltages show no signs of CL;

that log does show commanded LAMBDA going to 1.000... post the tune file that this log was taken from.

That log does not show CL, the HO2Sx1 voltages show no signs of CL; That is true, really, what I was after is why it went to Lambda after over 8 seconds of wot
IT does it at random times though ,some times it doesn't do it at all
