ECU Editor With Wideband O2 Enabled

[SimiPair]

What effect on the ECU does installing a wideband O2 sensor and enabling the sensor in ECU Editor? What additional control over fueling does this afford?

If you have a wideband controller you can connect the 0-5 vdc output signal to the stock O2 sensor input and log the AFR readings (with a data logger or with a laptop hooked up and running real time) at each rpm and throttle position/MAP bin. You you then either make manual adjustments based on the logged data or enable the autotune function and have it come up with new values for the map to achieve your desired air fuel ratio.

The auto tune works pretty good IMHO.

Do I need a data logger? How do I enable Autotune in the ECU Editor?
