Lean spikes going from closed loop to open
Posted: Sun Sep 25, 2011 1:41 pm
Problem is that sometimes when car idles and I try quickly to accelerate car lean spike occurs. It happens when moving from traffic lights and etc. From logs I see that AFR goes from closed loop to open before lean spike occurs, lean protection enabled. So sometimes lean protection kicks in and I get power dips when starting to move. I know that lean protection can be switch off or just reconfigured with different values, but from where such AFR lean spikes ?
