AFR

AFR table

Specifies the desired air-fuel ratio depending on the RPM and load

  • 14.7 - stoichiometric AFR
  • 15-16 - lean AFR (economy, high EGT)
  • 10-13 - rich AFR (maximum power)

Lambda control

Provides automatic injection time adjustment according to lambda probe signal.

When using a narrowband sensor - correction only works in cells with a value of 14.7. Therefore, for the proper operation of the lambda control with a narrowband sensor, you need to set AFR = 14.7 throughout the map (except for power modes).

Narrowband speed

Sets the correction speed. If speed is too low - correction will be very slow. If speed is too high - it will cause lambda correction value fluctuations in steady operating modes.

Speed at idle

Sets the correction speed on idle. On idle, sensor response is slowed down, thus requiring to lower the correction speed.

PID

This is PID controller coefficients for the wideband labmda control.

Cold engine AFR limit

You can set richer target for cold engine, to stabilize it's operation. AFR target can be reacher, but can't be leaner than specified.

Open loop

You can set conditions for open-loop operation
