I got a question about "duty cycle".
This is in the lower rpm ranges just after launch. 2 different tracks duty cycle is the same for a given rpm IE 3500, 3700, 4000, etc. Ambient temp is 20 degrees (Celsius) different
O2 sensor readings are way different? On the cooler day the O2 shows it is much richer.
Should that be the be the other way around?
