I'm trying to learn and understand how my ECU and subsequent map has been configured.
The Lambda is narrow band and shows as connected, but I am only 99% sure it isn't being used for corrections in any point in the calibration.

My reasoning, is under: Run-mode Fuelling/Corrections/Closed Loop Lambda/Overall Enable is set to Disabled

with this disabled, I believe the lambda readings are not used to determine any fuelling, no matter what the CAL switch etc is set to.

Is this theory correct? or can it be overridden on an individual basis somewhere else in the config?

Thanks for any help.

If it is disabled, then no corrections will be taking place.

I don't even think very many would even try using a narrowband sensor, nor would you want to really.

Get a NTK wideband

Many thanks for the reply.

it appears that your ECU's closed-loop lambda control is disabled. Closed-loop lambda control uses the lambda readings from the oxygen sensor to make fueling corrections in real-time. With the "Overall Enable" set to "Disabled," it suggests that the lambda readings are not being used to determine fueling corrections.

I also think the lambda index is not being used correctly.

Yes, you're correct.
