The range of the original ECU is from 5 to 95%.
At open loop the initial set up of the CO screw with the original ECU should result 0.4-0.8% CO, then (normally) when changing back to closed loop the Duty Cycle rises a bit till it swings around 55%.
Your workflow above shows clearly that the sensor reads a value which does let the ECU think its too rich for lambda 1 (AFR 14.7:1) and so it pulls the duty cycle down.
How is your setup in detail?
- Does the AEM Wideband controller –beside the signal for the gauge– provide also a simulated narrowband signal (Like Innovate controller do) which you use as signal for the ECU?
- Or do you use two sensors, one original sensor with signal for the ecu and another wideband with signal for the AEM controller?
