Unable to edit sensor linearization breakpoints

As per title - just inputting some linearization data for a temp sensor - the option to 'edit breakpoints' is there but the OK button is greyed out:

Any ideas?

Never used that before, but if you want to edit the linearisation, first choose the linearisation type you want (e.g. extrapolation) then Edit Points from the linearisation menu.

I don think you can edit the breakpoints.

But in most cases they should be a sensible scale that they shouldnt really need changing ?

What do you need to alter ?

I did it the same as Tim:

Select liNearization, then Select Type, select interpolated or extrapolated (or other) as required, then liNearization and Edit Points, add the values you have from your sensor provider, and then liNearization and Apply.

Thanks!

It was for my Autronic PTC air temp sensor:

Also set up my default low and high voltages - using Interpolated as the type I get something that looks like what I'm after:

AWSOME!! was really looking for this when doing a twin dbw engine with 2 slightly different sensor voltages at the default zero voltage
