Afr fluctation on closed loop Kpro4

Hondata,
i have done a few test with a Ek swapped with a k20 engine and Hondata Kpro4 with a tech edge wideband wired in analog input 1.
I tune the calibration on open loop mode and it work very good, with afr flat in a wot 4th gear but when turn it on closed loop wideband, the ecu try to correct the afr with a lot of fluctation..
This like and PID control not properly setting...

i attach the log and the calibration

The wideband response is too slow and/or the voltage output is mismatched. Most people use AEM widebands; we find PLX work well.
