I'm trying to figure out this A/F ratio thing, and what creates power.
Now my understanding is that somewhere between 13.1:1 and 13.3:1 creates the most power... is this true?
My understanding is that under light load we can lean out the mixture upwards of 14.6:1 to increase fuel efficiency. We don't want to do this under heavy loads as it will create too much heat, and too little power.
Is this all correct?
So what I don't understand is why I would ever set levels under 13.0:1...
Most maps finish at full throttle in the higher RPM ranges between 12.5 and 12.8:1... why? I understand that this would cool the engine, but we don't run the engine at 9000rpm 100%throttle for hours and hours. Does a richer mix create more power under some specific set of circumstances? Why would I ever set the A/F ratio richer than 13:1?
