OK I'll do that.

What I'm seeing for AFR Commanded ranges between 13.2 and 13.7 which seems rich to me. My measured AFR is running 12.2 to 13.5 mostly, with an offset generally under 1.5 and this is at very light throttle application, generally around 20-30 kPa.

What would be the best way to bring these numbers up closer to stoich?
