Lambda regulation PID settings
Posted: Wed Nov 11, 2015 10:39 am
Dear all,
I have a question regarding the lambda regulation of the EMU. When I set the PID settings to default the EGO is onctrolling the mixture good at idle and low loads but on high engine speeds it is slow. To compensate I change the PID settings so it would adjust faster at higher engine speeds. The downside is that this causes the EGO controller to go to fast when the engine is idling. (causing lumpy idle due to large injection time deviations).
I know that most EGO controllers should take the engine speed into account using there PID control. Is the EMU also doing this?
Currently I disable the EGO controller during low <1200 rpm engine speeds to avoid lumpy idle due to large corrections. I do think the Autotune feature would work faster if the PID is engine speed related.
Best regards,
Tomba
