Ok, made a little drive with the 2.0 zvh rst on megasquirt an made a log vieuw.

The afr seems to be jumpingup and down a lot because the injector pw and duty cucle also is.

What could be causing this?

Should i set the fuel down in the ve table or is it correcting to fast and overcompensating the fuel..

all input is welcome

see the middle graph, red is afr
