gday lads,

can someone give me the run down on how to interperate them? (rich / lean )
ideally, where should the i6 be sitting?

thanks

OK... narrowband meter i assume.

When you're cruising, it should "sweep" from lean to rich, back and forth - effectively "average" stoichometric (the middle point of the gauge). This is how EEC acieves a desired A/F ratio when crusing - and it will target 14.7:1 (stoich ratio) when crusing.

Under compression, for example, in 2nd gear going downhill with no throttle, the gauge should read lean.

When giving more than, say, 50% throttle, the gauge should read rich.

thank you good sir.
