Linking Scan Tool To Editor

I agree with your second image it should be captioned with SAE.MAP or MAP:BARO Ratio with units in kPA not ECM.AFRATIO_M.

Thanks.

Thanks.

AFRATIO is automatically shown as the linked PID because that was the only PID in the log file with units that matched the axis units.
I.e. the axis has units of :1 and the AFRATIO PID has units of :1 so V8 tried to be "clever" and assumed that since both values are using units of ":1" then they can be linked - that's not accurate. However there is no trivial way for the V8 software to know that, since it is only using the units to make that decision.

If you didn't have AFRATIO as a selected PID then it would not automatically show up as the linked PID.
If you had another PID with units of :1 (i.e. a calculated PID that computed BARO/MAP) then neither PID would be auto-selected and you would have to select one of AFRATIO or that calculated PID from the drop down list.

Okay, I think I got it ! I changed my Calculated PID from 'factor' to ':1'. Now it is an option in the drop down box in V8 Editor for that Table and it seems to track with the Scan Tool file.

MAP_BARO="Calculated MAP-BAROMETER RATIO",:1,3

Thank you for explaining how V8 Editor works, it might come in handy for another Table.

Sorry I took so much of your time,
