Wideband 02 sensor autotuning setup

1. Disable EGR (1.8 ECU only)
2. Go to the INJ / O2 keypad screen
3. Hold both middle keypad buttons down while doing step 4 below.
4. Use the left buttons to switch between O2 and W2. The value displayed for W2 in that screen will be 128 minus (25.6 times the WBO2 voltage).
5. Change the six lambda target zone values to the WBO2 voltages you want. Multiply each voltage by 25.6 and subtract that amount from 128 to get the lambda target zone value.
