It appears you have forgotten to give us the information which you are asking about. What is it you are asking?

Spot the difference... (lack of datalog ELD prompt)

Taken from the help file you are referring to:

Closed Loop Settings
<insert your image here>

The minimum and maximum short term adjustment sets the limits for the short term fuel trim. The values are expressed as a percentage adjustment of fuel eg. -10% means that the short term fuel trim will not remove more than 10% fuel from the table.

Use secondary 02 input for closed loop operation - uses the oxygen sensor connected to the secondary o2 sensor pin as the primary oxygen sensor for closed loop operation (PRA only).

Datalog ELD voltage - not in operation.

Err... maybe I should have been clear

the datalog ELD prompt is missing??

what do I have to change/do to get the option?

Datalog ELD voltage - not in operation.

So what does that mean?

it's no longer a supported feature or what?

All I am trying to do is get an LM-1 to datalog using the ELD input, are you saying this is NO LONGER avaliable?

I had assumed that I have just missed another prompt/option somewhere?

Go to Help, Contents and search for "wideband input". Look at the settings topic.

It is impossible to read your mind and know what it is you are trying to do unless you fully explain it.

With all due, I have read that several times now, the issue I have is that the prompt for datalog ELD voltage is just NOT there...

I am assuming there is another setting required first for this to appear?

this is working from a stock PRA Kal....

Take one step back. What are you trying to do? If you're trying to datalog a wideband from the ELD then in settings set the wideband input to the ELD. The setting on the Parameters window is no longer used.

Do you have any plans to allow the wideband input using ELD input for closed loop operation on the PRA ECU rather than just for datalog purposes? Will it be possible to let the ECU alter the air and fuel input mixture to achieve the desired A/F output? Is this what the PRB and PRC ECU's are capable of?

No ecu can use an aftermarket wideband signal to run in closed loop. THis is not something that the software will feature in the future.
