Displaying an MVPI input in a chart.

[DaveNY]

I am pulling dual widebands into my channels using the MVPI3 red and blue inputs. transforming it to E85 EQ ratio. no problems there, data is reading in the channel list during logging. but i also want to display them in the chart. both as EQ and as AFR. but no matter what i try i cant get them correct. is it possible? could someone look my log and scanner layout and help. thanks

Reading some other posts, i just realized that in my math parameters, the User defined items that use the External MVIP inputs 2.1 & 2.2 are all highlighted in red. meaning i am not loging them. but i am, is this normal behavior?

The pink user math variable means you aren't logging that PID. You will need to add the analog inputs to your channel list and transform the voltage signal into EQ/AFR. What widebands do you have?

I am using a pair of Spartan V2's. They are in my channels and pulling data being transformed to EQ

what i have found from playing around with it is this:
If you add External Input and transform it to EQ, EQ ERR graph will populate, but channel will not put out data on a chart (either straight up or with USER Math, parameter shows with pink highlite) see attached screengrab
If you add External Input and log as voltage, EQ ERR graph will not populate (even with USER Math applied), but channel will show in a chart (either straight up or with User Math)

i want to have the EQ ERR graph and show the data in a chart both as AFR and EQ. On 5.0.4 not using beta Ver.
