Afr fluctation on closed loop Kpro4
Posted: Thu Nov 03, 2016 4:04 pm
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
